Cadaver and angiographic studies show that the incidence of unilateral transverse sinus is rather infrequent (2.5%) and absence of any communication at the torcular is even rarer.36,37 Despite this, given the catastrophic results of ligating a unilateral SS, a preoperative arteriogram or magnetic resonance venogram is recommended. The most significant draining vein of the temporal lobe is the inferior anastomotic vein (vein of Labbé). They are usually small, and are highly variable with respect to their size, connections and location. Basically, the cerebral veins are divided into superficial veins and deep veins. Its rostral portion may be hypoplastic as a normal variant. The vein of Trolard, or the superior anastomotic vein, is the primary connecting midline afferent and usually enters into the SSS in the postcentral region. Background: Vein of Labbe is the major inferior anastomotic channel that connects the middle cerebral vein to the transverse sinus. They are mostly unnamed, except for three major anastomotic routes: (i) the superficial middle cerebral vein; (ii) the superior anastomotic vein; and (iii) the. The dura mater has two layers: the inner ormeningeallayer, and the outer periosteal or endosteal layer. The dura mater (Latin for “tough mother”) with its varied reflections segregates the brain into structural compartments. They are mostly unnamed, except for three major anastomotic routes: (i) the superficial middle cerebral vein; (ii) the superior anastomotic vein; and (iii) the inferior anastomotic vein. However, they are clinically important as a path for infection to spread into the cranial cavity. Also important know here about Vein of Trolard, also known as superior anastomotic vein, often located in post central sulcus, connects the superficial middle cerebral vein of Sylvias from sylvian fissure to the superior sagittal sinus. Charles Labbé (1851-1889 The deep white matter, basal ganglia, and subependymal regions are drained by the deep component of the inner segment. The occlusion of veins in the venous system is called venous sinus thrombosis. Anteriorly, drains into cavernous sinus. The septal and thalamostriate veins join to form the paired internal cerebral veins in the area of the foramen of Monro. The great cerebral vein of Galen is approximately 1 to 2 cm long and passes posterosuperiorly behind the splenium of the corpus callosum in the quadrigeminal cistern. Beneath the splenium of the corpus callosum, the internal cerebral veins join each other to form the great cerebral vein of Galen, which is joined by another major paired venous structure, the basal vein of Rosenthal. Information about the termination of the inferior anastomotic vein of Labbé is of crucial importance in the subtemporal neurosurgical approach and its modifications. 1, superior sagittal sinus; 2, superficial cortical veins; 3, inferior sagittal sinus; 4, great cerebral vein of Galen; 5, straight sinus (or sinus rectus); 6, transverse sinus; 7, occipital sinus; 8, sigmoid sinus, draining to internal jugular vein; 9, cavernous sinus; 10, inferior petrosal sinus; 11, superior petrosal sinus; 12, basal vein(s) of Rosenthal; 13, choroidal veins; 14, internal cerebral vein(s); 15, torcula (or confluens sinuum). The deep group of veins consists of the internal cerebral veins, basal veins (of Rosenthal), and great cerebral vein (of Galen) and their tributaries. Darkened structures represent deep cerebral veins as described in the legend to Figure 2. In addition to superior superficial veins that empty into it, the SSS also receives emissary veins that drain the scalp. A prominent inferior anastomotic superficial vein of Labbé can also be seen that connects the transverse venous sinus. New York: McGraw-Hill, 1987:51. Cerebral blood flow. Susan Stranding DSc SSP. The superficial middle cerebral vein is the largest of the three, and it drains into the cavernous sinus. J. Neurosurg. However, hemorrhage is more common than ischemia in the venous system. Injury to the vein of Labbé, particularly in the dominant hemisphere, can cause an infarct in the posterior hemisphere with severe, permanent neurologic deficit. The Labbe is the largest vein draining the temporal convexity towards the transverse or sigmoid sinus. A left superior surface vein (unlabeled) is located next to the dominant inferior surface vein … Notable in this group are the internal cerebral veins, the basal vein of Rosenthal, and the great cerebral vein of Galen (Figure 2). There have been case reports of ligation of the vein of Galen without significant clinical sequelae, but this is likely due to the development of collateral circulation and to the significant anatomic variation of the vein of Galen and its tributaries.28,29, Jahangir Moini, Pirouz Piran, in Functional and Clinical Neuroanatomy, 2020. 1, Basal vein of Rosenthal; 2, great cerebral vein of Galen; 3, internal cerebral vein(s); 4, deep middle cerebral vein; 5, superficial middle cerebral vein (cutaway). The torcula divides into transverse (lateral) and occipital sinuses; the latter is typically rudimentary. This vein runs in the groove between the thalamus and caudate nucleus, draining a large amount of blood from these structures. The inferior anastomotic vein (of Labbe), however, was predominant on the left hemisphere. Clinical manifestations may include headache because of increased intracranial pressure, motor problems, and seizures. Methods These include the following: Superficial middle cerebral vein—running anteriorly and inferiorly, along the lateral sulcus. There are nowhere near as many vascular problems related to the venous system as to the arterial system. The basal vein (of Rosenthal) drains various cortical areas. A collection of emissary veins connects the extracranial veins and dural sinuses. Mostly anastomose with the deep venous system A nondominant sinus in the presence of a patent torcular can be sacrificed in selected cases. 2. 8.22). Inferior group. The vein of Labbé (inferior anastomotic vein) is part of the superficial venous system of the brain. Trolard, by the way, is just a name for a big parietal vein — superior, inferior parietal, whatever. The appearance and structural anatomy of the vein itself appears to … Several tributaries drain inferior areas of the basal ganglia as well as the orbital surface of the frontal lobe. The veins of the central nervous system drain deoxygenated blood from the cerebrum, cerebellum, brainstem and spinal cord. Because the dural sinuses contain the pacchionian or arachnoid granulations, thrombosis can lead to intracranial hypertension and papilledema. They receive tributaries that drain subcortical and periventricular structures as well as the choroid plexus within the lateral ventricles. Labbé vein - an inconstant vein that passes from the superficial middle cerebral vein posteriorly over the lateral aspect of the temporal lobe to enter the transverse sinus. The inferior anastomotic vein, also known as vein of Labbé, is part of the superficial venous system of the brain. Figure 4. In this patient, the left inferior cerebral vein entering transverse sinus was very small and there was no anastomotic branch between transverse sinus and superficial middle cerebral veins. This is especially the case in the 10% of cases where the vein is located anteriorly. They consist of a superior group, which empties into the superior and inferior sagittal sinuses, as well as an inferior group, which empties into the transverse and cavernous sinuses. The veins of the posterior fossa are highly variable, and are divided into four groups: (i) superficial veins, which drain the cortical surfaces of the cerebellum; (ii) deep veins, which course in the fissures between cerebellum and brainstem, as well as the veins on the cerebellar peduncles; (iii) brainstem veins, which drain the brainstem and course either transversely or horizontally; and (iv) bridging veins, which drain into either the vein of Galen, petrosal sinuses or tentorial sinuses.20. In general, superior superficial veins drain upward toward the SSS. In the supratentorial compartment, superficial drainage of the cortical structures is ultimately channelled into the superior sagittal sinus or the transverse sinus (Figure 2.5). The vein of Labbé, or inferior anastomotic vein, connects the superficial sylvian vein and the transverse sinus. The superior anastomotic vein (of Trolard) courses cephalad from the posterior aspect of the Sylvian fissure towards the midline over the convexity, and empties into the SSS. A situation in which thin-walled veins, presumably subject to local pressure, are emptying into sinuses not affected by rises in intracranial pressure may have implications in the management of patients with increased intracranial pressure and altered autoregulation, but they are still poorly understood (28,29). This vein bends superiorly, joining the inferior sagittal sinus, forming the straight sinus. The Rolando is a named vein, running by definition in the Rolandic sulcus, anterior to Trolard. The vein of Labbé (inferior anastomotic bridging vein group) is a dominant bridging vein that courses obliquely along the inferolateral surface of the temporal lobe, projecting inferoposteriorly and draining into the transverse sinus (Fig 11). The vein of Labbe is part of the … They have only minor effects on the brain's normal pattern of circulation. The superior anastomotic vein (of Trolard) was observed with similar frequency in each type. The vein of Labbé, also known as inferior anastomotic vein, is part of the superficial venous system of the brain. The SS can be opened and packed with Surgicel and its lumen sutured, or it can be ligated and clipped. This is a tortuous vessel, draining the choroid plexus of the body of the lateral ventricle. It curves around the cerebral peduncle, entering the great vein. The muscle graft is placed between and sutures are tied, resulting in bending and obliteration or the lumen. Fig. Note its multiple septations and the contiguity of venous channels to the opposite cavernous sinus. As can be surmised by first principles, there is a relationship between the size of the terminal superficial middle cerebral vein, the anastomotic vein of Trolard and the vein of Labbé, as all three share a similar drainage territory. This bend is the venous angle, which is used in imaging evaluations to reveal the site of the interventricular foramen (see Fig. A good landmark for division of the anterior and middle one-third of the SSS is the coronal suture. This accounts for the frequent occurrence of cerebral venous thrombosis as a complication of infectious pathologies, such as in cavernous sinus thrombosis in facial infections, lateral sinus thrombosis in chronic otitis media, and sagittal sinus infection in scalp infections. FIGURE 2.6.. These are the septal vein, which runs posteriorly across the septum pellucidum, and the thalamostriate vein, also called the terminal vein. The confluence of sinuses (confluens sinuum) is formed by the junction of the straight sinus, the superior sagittal sinus, and both transverse sinuses (Figs. Superficial cortical veins, 4, drain into the superior sagittal sinus (not shown) in a characteristically oblique direction, against the direction of blood flow within the sinus. The SSS increases in size from anterior to posterior and ranges in width from 4.3 to 9.9 mm.27 As mentioned, the sacrifice of the anterior one-third of the SSS is usually well tolerated, but complications can include akinetic mutism, short-term memory deficits, or personality changes from compromise of prefrontal afferent drainage. The vein of Labbé, or inferior anastomotic vein, connects the superficial sylvian vein and the transverse sinus. On each side, the basal vein forms near the optic chiasm by the deep middle cerebral vein. The internal cerebral veins are paired midline vessels that arise at the foramina of Munro. A “duplicated” vein of Trolard may be present, in which case two equal-sized anastomotic veins connect the SMV territory with the superior sagittal sinus. Generally, mesencephalic, pontine, and superior vermian drainage finds its way to the galenic system. A series of prominent veins serves as landmarks on the cortical surface, including the rolandic vein, which drains the central sulcus (and therefore the precentral and postcentral gyri). The venous blood in these channels and from the corpus callosum and the interior of the hemisphere (internal cerebral veins) drains into the great cerebral vein (of Galen) and then into the straight sinus. Partially, this is true since occlusions or thrombosis occur less often in the venous system. The vein of Trolard is usually smaller than both of these. The primary deep vein is the internal cerebral vein, formed at the interventricular foramen. The, Redrawn with permission from Kahle W, Leonhardt H, and Platzer W (1986), Redrawn with permission from Nolte J (1999), Redrawn with permission from Osborn AG (1994), The embryologic basis for the anatomy of the cerebral vasculature related to arteriovenous malformations, The superficial group of veins drains blood from the cortex and subcortical white matter. They enter the sinus obliquely, and the direction of flow within the veins is typically opposite that within the sinus. The inferior anastomotic vein (of Labbe) runs from the middle or posterolateral aspect of the Sylvian fissure caudally towards the anterior portion of the transverse sinus, and empties into the transverse sinus.15. It encircles and drains the brainstem beneath the uncus and parahippocampal gyrus, lateral to the cerebral peduncle, mesencephalon, and quadrigeminal plate, before heading superiorly to join the vein of Galen. E.K. The deep middle cerebral vein continues along the medial surface of the temporal lobe. Fundamental Neuroscience for Basic and Clinical Applications (Fifth Edition), Schmidek and Sweet Operative Neurosurgical Techniques (Sixth Edition), The trans-sigmoid approach can be used as part of any posterior transpetrosal approach. The vein of Trolard is smaller than both of these. The inferior anastomotic vein, also known as vein of Labbé, is part of the superficial venous system of the brain. There is also a series of anastomotic veins communicating the middle cerebral vein with the superior anastomotic vein of Trolard and the inferior anastomotic vein of Labbé. The thalamostriate drains subependyma of the remainder of the lateral ventricles and provides some drainage from the basal ganglia and thalamus. These large anastomotic veins form channels between the superior sagittal and transverse sinuses and the superficial middle cerebral vein. Other small-caliber midline veins can be taken with minimal risk. The cerebral veins are roughly divided into superficial cortical and deep groups. Inferior anastomotic vein (of Labbé)—running posteriorly and inferiorly across the temporal lobe, connecting the superficial middle cerebral vein with the transverse sinus. They join in the superior cistern, forming the unpaired great cerebral vein or the vein of Galen. On the other hand, the dural sinuses arise as separations in the laminae of the dura, and therefore have tough, fibrous walls and are not readily subject to deformation. Cortical vein thrombosis is usually secondary to retrograde extension of dural sinus thrombosis. Additional connecting channels extend to plexuses within the vertebral canal. Sacrifice of the midline central group of veins within 2 cm posterior to the coronal suture carries a significant risk. Posterior fossa and presigmoid dura are exposed first, and parallel suture is passed in front and back of the sinus. Its location is also highly variable: The anatomy of the vein itself is also variable, with a dominant single channel, multiple branching channels and even venous lakes having been described. They empty into the venous dural sinuses and finally, into the internal jugular veins. The cerebral venous drainage system is divided into an inner segment, consisting of the cerebral veins proper, which provide drainage for the brain, and an outer segment, comprising the dural venous sinuses, into which these veins flow (27). Copyright © 2021 Elsevier B.V. or its licensors or contributors. Relatively smaller anterior surface cerebellar veins (black) drain into the mesial aspect of the superior petrosal sinus. It is eponymously named after French surgeon Charles Labbé (1851-1889) who described it in his 3rd year of medical school. The vein of Labbé is ostensibly responsible for drainage of the temporal lobe, and injury to it may result in considerable swelling. The superficial middle cerebral vein (of Sylvius) runs in the Sylvian fissure, drains the peri-Sylvian cortex, and empties into the cavernous sinus, sphenoparietal sinus or pterygoid plexus. It is thought to approximate the course of the anterior choroidal artery for a significant portion of its length. travels along the ___ lobe, trains into the ___ sinus, and connects the _____ with the _____ ), Encyclopedia of the Neurological Sciences (Second Edition), ). Philadelphia: Lea & Febiger, 1987. The purpose of this study was to examine the detailed anatomy and variations of the vein of Labbé (VL) from microsurgical perspective. The SSS extends along the superior border of the falx cerebri (Figure 3). The deep venous drainage of the brain commences with deep medullary veins, which form 1 cm to 2 cm below the cortical surface.11 These drain the subcortical and deep white matter centrally towards subependymal veins, and then into the deep venous system. ), (From: Millikan CH, McDowell F, Easton JD. Compared to the superficial veins, the deep veins have a more constant appearance. This article discusses the venous drainage of the brain and relevant clinical conditions such as cavernous sinus thrombosis. Superior cerebral veins: drain the superior surface; empty into the SSS, Superficial middle cerebral vein: drains the lateral surface of each hemisphere; empties into the cavernous or sphenopalatine sinuses. It turns caudally at the level of the petrous apex and is contiguous with the sigmoid sinus, which is located in an S-shaped groove in the mastoid portion of the temporal bone. Rather than a true confluence, the superior sagittal sinus usually drains into the right transverse sinus and the straight sinus into the left. The mesial temporal lobes are retracted on either side. Surgically it is of importance in planning temporal lobectomy for refractory temporal epilepsy, as the vein should be preserved, often requiring some cortical tissue to be left behind. It usually penetrates the SSS in the postcentral region. The superior anastomotic vein of Trolard connects to the superficial middle cerebral vein and can drain either superiorly into the superior sagittal sinus (SSS) or inferiorly into the superficial middle cerebral vein and then into the cavernous sinus. Unlike cerebral arteries, they are interconnected by many functioning anastomoses, both within one group of veins, and between superficial and deep vein groups. The galenic or deep venous circulation. Internal or deep cerebral veins. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. FIGURE 2.5B.. Additional figure portraying the cerebral venous system. Major veins of the lateral cortical surface. Midline afferents are primarily encountered when using interhemispheric approaches. Superior anastomotic vein (vein of Trolard): connects the superficial middle cerebral vein and the SSS, Inferior anastomotic vein (vein of Labbé): connects the superficial middle cerebral vein and the transverse sinus, The deep veins of the brain drain into the confluence of the Galen complex, which, in turn, drains into the straight sinus. Review of the literature reveals few cases of isolated thrombosis of either the inferior anastomotic vein of Labbe or vein of Trolard [1-11]. Neither system has valves, which are found in venous structures elsewhere (27). By continuing you agree to the use of cookies. Eponymously named after the French surgeon Charles Labbe, the vein of Labbe (inferior anastomotic vein) crosses the temporal lobe between the Sylvian fissure and the transverse sinus and connects the superficial middle cerebral vein and the transverse sinus. Cortical veins at the surface of the brain are mostly unnamed and are highly variable in their anatomy, but three veins deserve specific comment. The septal vein drains the deep white matter of the frontal lobes, subependymal area of the frontal horns, and septum pellucidum. the superior anastomotic vein of Trollard is the ___ superficial vein. Learn more about the anatomy of … The cavernous sinuses are also contiguous with an additional (basilar or periclival) venous plexus that extends inferiorly to the level of the foramen magnum. Change in the direction of flow can occur in these anastomotic veins to equalize pressure differentials that may occur in the setting of sinus occlusions, thromboses, space-occupying lesions, or other factors. Just beneath the splenium of the corpus callosum, the unpaired great cerebral vein of Galen is formed by the convergence of the aforementioned major veins. Figure 2. The two internal cerebral veins run posteriorly through the transverse cerebral fissure. The meningeal veins are small venous channels that drain the dura mater. It has a short course, and is joined by the basal veins. This has also been referred to as the galenic circulation (Figure 2.6). It courses posteroinferiorly from the mid-Sylvian fissure connecting the superficial middle cerebral vein to the anterolateral portion of the transverse sinus. Along with draining the brain immediately adjacent to it, the vein of Labbé also gathers draining tributaries from medial, anteroinferior, and posteroinferior temporal lobe in 80% in cadaveric dissection. This approach is advantageous in cases of tumor growth into the SS with spontaneous obstruction. Inferior Anastomotic Vein of Labbe. Named after the French surgeon Charles Labbé, the vein of Labbé (also known as the inferior anastomotic vein) crosses the temporal lobe between the Sylvian fissure and the transverse sinus and connects the superficial middle cerebral vein and the transverse sinus. These layers fit snugly into each other in almost all locations except for certain avenues, where they split to accommodate the venous channels. The superficial veins usually lie on the surfaces of the cerebral hemispheres. Just after it forms, the internal cerebral vein has a sharp posterior bend. The vein of Galen then joins the inferior sagittal sinus to form the straight sinus. Temporary clipping across the SS is recommended to assess for the presence of temporal lobe or cerebellar swelling. Understanding the pathophysiology of venous thromboses and infarctshelps to explain the imaging manifestations and natural evolution ofvenous infarcts. Injury to the vein of Labbé, particularly in the dominant hemisphere, can cause an infarct in the posterior hemisphere with severe, permanent neurologic deficit. Venous thrombosis can occur spontaneously or secondaryto trauma, infection or as a complication of surgery. This is formed lateral to the optic chiasm by the union of a deep middle cerebral vein and an anterior cerebral vein. Venous anatomy is highly variable between individuals, and many veins are unnamed, with several notable exceptions. Veins draining the inferior aspect of the cortical convexity generally empty into the superficial middle cerebral vein and then into the cavernous sinus. Frank D. Vrionis, ... Jason A. Brodkey, in Schmidek and Sweet Operative Neurosurgical Techniques (Sixth Edition), 2012, The trans-sigmoid approach can be used as part of any posterior transpetrosal approach. The great cerebral vein of Galen is variably 0.5 to 2 cm in length (31). Fibrous septa at the inferior angle of the sinus, in addition to turbulent flow from draining superficial cortical veins, are felt to account for a greater risk of SSS thrombosis. Labbé triangle - an area where the stomach is normally in contact with the abdominal wall. The sigmoid sinuses drain into their respective internal jugular veins. Small-caliber veins in this system can usually be sacrificed with minimal consequence if they do not contribute significantly to the Labbé system. Great Vein of Galen (Great Cerebral Vein) 1) Travels through superior cistern 2) Drains cerebellum and medulla. A series of prominent veins serves as landmarks on the cortical surface, including the rolandic vein, which drains the central sulcus (and therefore the precentral and postcentral gyri). Inferior cerebral veins: drain the inferior aspect of each cerebral hemisphere; empty into the cavernous and transverse sinuses. Occlusion of the posterior one-third of the SSS, or the torcular Herophili, carries a significant risk of potentially fatal diffuse brain edema. Synonym (s): inferior anastomotic vein Medical Eponyms © Farlex 2012 1, superficial middle cerebral vein; 2, superficial anastomotic vein of Trolard; 3, inferior anastomotic vein of Labbé. Sood S, Asano E, Chugani HT. 2 ; Table 1 ), when compared with that of the cadavers. 8.20). Figure 1. Along with the superficial and deep veins, there is a separate and complicated collection of veins serving the cerebellum and brainstem. There was no significant difference in the number and diameter of the veins of Labbé as measured by CTV and DSA (Fig. The venous drainage of the posterior fossa may be somewhat variable (33). 1. Gray's Anatomy. The vein of Labbé is the largest channel that crosses the temporal lobe between the Sylvian fissure and the transverse sinus and connects the superficial middle cerebral vein and the transverse sinus. A unique aspect of the venous drainage is that the cerebral veins proper are thin walled, compared to systemic veins, and do not consist of the usual histologic layers of tunics. Miyawaki, in Encyclopedia of the Neurological Sciences (Second Edition), 2014. The cerebral veins on the lateral surface of the hemisphere drain into the superior sagittal and transverse sinuses and into the superior anastomotic vein (of Trolard) and the inferior anastomotic vein (of Labbé) (Fig. to the superior sagittal sinus by the great anastomotic vein of Trolard; to the transverse sinus by the posterior anastomotic vein of Labbé; Vascular territories: perisylvian area, anterior temporal lobes, with the Vein of Labbe draining posterior temporal and lower parietal lobes. It runs along the medial surface of the temporal lobe and empties into the great cerebral vein of Galen. The paired transverse sinuses are typically well formed but often asymmetrical, with the right usually dominant. In addition to the paired internal cerebral veins, the Galen system also receives the paired basilar veins of Rosenthal (which begins at the anterior perforated substance by the union of the anterior cerebral vein, the middle cerebral vein, and the striate vein); the veins from the corpus callosum, the cerebellum, and the occipital cortex; and the vermian precentral vein. The superficial sylvian vein is formed from the connection of the temporosylvian veins and enters into the cavernous sinus. Orlando: Grune & Stratton, 1984:14. This vein drains the insula. Similar to cerebral arteries, these veins can be visualized by angiographic imaging. 5.3. ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. The major draining vessels include the septal and thalamostriate veins. Most of them empty into the superior sagittal sinus. Therefore, an occlusion that slowly develops in the anterior region of the superior sagittal sinus most likely would have no clinical manifestations. Exposure is increased by ligating the SS, usually between the superior and the inferior petrosal sinuses or between the, Primary Brain Lesion Resection Complications, ). Injury to the vein of Labbé, particularly in the dominant hemisphere, can cause an infarct in the posterior hemisphere with severe, permanent neurologic deficit.
