Patients and methods: A total of 100 consecutive patients underwent PSI MR examination. In type 1, only the thalamostriate vein collects blood from the basal nuclei and the LDV is absent. The confluence of the great cerebral vein and inferior sagittal sinus forms the straight sinus. The scanner settings were as follows: 120 kV, 200 mA, and 64 × 0.625 mm section collimation. • Types 2 and 3 warrant consideration during surgical approaches to the body of the lateral ventricle because a sacrifice of a major vein draining the basal nuclei may result in serious complications, such as venous infarction. The veins at the anterior poles of the thalami merge posterior to the pineal glandto form the great cerebral vein. Purpose: To evaluate the capability of venography based on MR phase-sensitive imaging (PSI) in the visualization of internal cerebral veins (ICV) and their tributaries, and to concurrently describe their anatomical variants. We also developed a new classification system of the deep cerebral veins draining into the ICV to increase the safety and quality of treatment and diagnosis provided by neuroradiologists and neurosurgeons worldwide. Deep Supratentorial Cortical Veins (Internal) Deep structures of the cerebral hemispheres, includ-ing the basal ganglia, corpus callosum, thalamus, and posterior part of the limbic system, are drained by the deep venous system, which has two major components: internal cerebral vein (ICV) and BVR [1]. * Tadeusz Popiela—UNRELATED: Employment: Specjalistyczna Praktyka Lekarska. Many tributaries of the internal cerebral veins extend beyond the corpus striatum into the white matter of the hemispheres. Symmetric types were found between the 2 hemispheres in 50 men and 110 women (59.5% and 66.3%, respectively). Enter multiple addresses on separate lines or separate them with commas. NOTE: We only request your email address so that the person you are recommending the page to knows that you wanted them to see it, and that it is not junk mail. Bifurcation of the TSV was noted in 23 right and 15 left hemispheres with the TSV present. Only 1-2 cm of cerebral white matter is drained by cortical veins, so that most of centrum semi-ovale and corona radiata is collected into tributaries of the internal cerebral vein. See ▶ Fig. The vein that accompanies the internal iliac artery; it merges with the external iliac vein to form the common iliac vein. The LDV, or the thalamocaudate vein,5,6 is located on the floor of the body of the lateral ventricle and enters the ICV at various levels.1 A prominent LDV drains blood from the lateral part of the body of the lateral ventricle and receives tributaries from the caudate nucleus. CTA may not have detected small veins terminating at the ICV because of insufficient resolution of this imaging method. Numerous researchers have reported differences in internal cerebral vein branching patterns but did not classify them. In type 4, the basal vein takes an unusual course and drains the basal nuclei. There are a total of 5 venous angle types (IA, IB, IIA, IIB, III).3 Types I and II refer to the relation of the venous angle to the foramen of Monro (adjacent to or located behind, respectively), whereas types A and B differentiate the ASV located at the venous angle (anteriorly) or beyond it (posteriorly). As stated above, the anatomy of the ICV tributaries is particularly important in minimally invasive procedures such as deep brain stimulation because placing an electrode properly ensures that no vessel is injured. Removal of a mass located in the body of the lateral ventricle exposes vascular structures localized beneath the lesion, and an LDV originating from the anterior or middle portion of the ICV courses farther in this area. Axial 0.625-mm slices at increments of 1.25 mm were reconstructed using a 512 × 512 matrix, with a standard kernel applied. 1072.6120.121.2018). B, The suprathalamic variants of the lateral direct vein (right hemisphere). The anterior tributaries of the internal cerebral vein usually fill and drain late at angiography (GREITZ), and the central veins therefore are still well filled when most of the contrast medium has disappeared from the superficial veins. For descriptive purposes, it may be divided into an anterior or horizontal portion and a posterior or descending portion. This is particularly clinically important in planning a third ventricle operation because the ventricle can be accessed more easily via the side on which the ASV–ICV junction is located posteriorly. The arrow indicates the TSV; the arrowhead, the medial atrial vein. Statistically significant differences were found neither between the hemispheres and the types in general (P = .23) nor between the types and sexes in general (P = .41). Arrows indicate LDVs. Our results show that 64% of the patients had different types of patterns of ICV tributaries in the left and right hemispheres. The small white arrows denote the collateral pathways. The thalamostriate vein is usually the largest tributary of the ICV. Numerous researchers have reported differences in internal cerebral vein branching patterns but did not classify them. The most common termination point was found to be the middle third of the ICV (64.52% of the right and 66.67% of the left hemispheres). Conclusions. The lateral direct veins were identified in 22% of the hemispheres, and usually they terminated at the middle third of the internal cerebral vein (65.45%). Preoperative assessment of veins coursing in the body of the lateral ventricle would help in the development of a dissection plan that minimizes the risk of vascular complications.14. The number of TSVs found was as follows: no TSVs in 17 hemispheres (9 right, 8 left), 1 TSV in 480 hemispheres (239 right, 241 left), and 2 TSVs in only 3 hemispheres (2 right, 1 left). The analysis was performed primarily on the MIP cross-sectional images (axial, sagittal, coronal). The Anatomical Quality Assurance Checklist of the International Evidence-Based Anatomy Working Group, Department of Anatomy, Jagiellonian University Medical College in Krakow, Poland, was used to ensure high-quality reporting of anatomic variants in this study.9 The Bioethical Committee of the Jagiellonian University, Krakow, Poland, approved the study (No. Great cerebral vein is just one vein (about 2 cm in length). 36.1.2 Radiologic Studies Last, we analyzed only white patients; thus, no interracial differences were investigated. The lateral direct vein is its other major tributary. The ICV begins at the union of the anterior septal vein (ASV) and the thalamostriate vein (TSV) at the posterior margin of the foramen of Monro.1 Other major tributaries that join the ICV include the lateral direct vein (LDV) and the medial atrial vein. The anterior septal vein–internal cerebral vein junctions and their locations in relation to the foramen of Monro also were evaluated. A, Normal ICV anatomy (type 1) in both the left and right hemispheres. 36.3 Left internal carotid artery injection in the venous phase in lateral view (a, enlarged view in b) demonstrates drainage to the medial parietal veins (1) toward the superior sagittal sinus, but also drainage from the septal veins (2), the thalamostriate veins (3), and the posterior atrial veins (4) into the ICVs, and from there, via an inferior thalamic vein (5) to the lateral mesencephalic vein (6), which opens to the superior petrosal vein. Tributaries of the internal iliac vein include the gluteal, internal pudendal, obturator, lateral sacral, anterior sacral, middle rectal, vesical, uterine, and vaginal veins. precentral cerebellar vein; superior vermian vein; anterior pontomesencephalic vein ; inferior cerebral veins (draining medial inferior temporal lobe) This “epsilon” shape of the venous drainage is typically seen in vein of Galen AVMs, where the deep venous system has not gained access to a normally developed straight sinus drainage. Coronal MR venography (d) with sagittal reconstructions (e) suggests occlusion of the vein of Galen with a straight sinus stump (1), persistence of a left-sided tentorial sinus (2), superior drainage into a medial parietal vein (3), and anterior drainage of the right basal vein of Rosenthal (4). Background and purpose: Thalamostriate vein (TSV) is an important tributary of the internal cerebral vein, which mainly drains the basal ganglia and deep medulla. Outside computed tomography revealed a large mass centered at the tentorial incisura, and she presented to neurosurgery. When the LDV was present, the TSV had a reduced diameter compared with the ipsilateral TSV in 38.95% of the hemispheres. RESULTS: We classified internal cerebral vein branching patterns into 4 types depending on the presence of an extra vessel draining the striatum. The number of ASVs that predominated in both right and left hemispheres among patients of both sexes was 1 (95.24% of right and 91.67% of left male hemispheres, and 92.77% right and 92.17% left female hemispheres). Bottom line is that tributaries of internal cerebral vein drain structures adjacent to the ventricles, and so understanding ventricle anatomy is more than half the battle. Our study was limited by the technique with which the ICV evaluation was conducted. Disclosures: Michał P. Zarzecki—UNRELATED: Grants/Grants Pending: Polish Ministry of Science and Higher Education, Comments: “The Best of the Best! The arrow indicates the LDV. Vascular Territory. The internal cerebral veins can be seen on the superior surfaces of the caudate nuclei and thalami just under the corpus callosum. The most common was termination at the venous angle (71.15% of the right and 73.06% of the left hemispheres). The various points of termination of the LDVs are presented in Table 2. The TSV receives several transverse caudate veins, and overall, it collects blood from the caudate nucleus, internal capsule, lentiform nucleus, claustrum, extreme capsule, and the white matter of the frontoparietal lobes.1,2 The U-shaped angle where the junction of the TSV and the ICV forms is called the venous angle1 and is an anatomic landmark for access to the third ventricle via the lateral ventricle.3,4 A true venous angle is adjacent to the posterior margin of the foramen of Monro, while a false venous angle lies behind it.3 Another important clinical aspect is the ASV termination at the ICV because the location of the ASV–ICV junction determines the limit of posterior enlargement of the foramen of Monro. An ASV terminating at the ICV at the venous angle is a disadvantage, while an ASV joining the trunk of the ICV is an advantage because it allows greater surgical exposure of the third ventricle. The deep group drains the deep white and gray matter and collects into channels that course through the walls of the ventricles and basal cisterns to drain into the internal cerebral, basal, and great veins. In the meantime many tributaries of the internal cerebral vein develop forming the subependymal and deep medullary veins. The internal cerebral veins (deep cerebral veins) drain the deep parts of the hemisphere and are two in number; each internal cerebral vein is formed near the interventricular foramina by the union of the superior thalamostriate vein and the superior choroid vein. BACKGROUND AND PURPOSE:The internal cerebral vein begins at the foramen of Monro by the union of the thalamostriate and the anterior septal veins. Two distinctly different types (asymmetric) of the ASV–ICV junction in both hemispheres were found in 41 men and 89 women. The ASV–ICV junction was divided into 5 types3 and was present as follows: type IA: 286 hemispheres (147 right and 139 left hemispheres); type IB: 99 hemispheres (52 right, 47 left); type IIA: 101 hemispheres (41 right, 60 left); and type IIB: 12 hemispheres (8 right, 4 left) (Fig 1). The increasing use of micro-operative techniques to approach the cerebral areas through which the deep cerebral veins course necessitates a thorough understanding of their course and drainage patterns. They receive tributaries that drain subcortical and periventricular structures … Hence, the objectives of this study were to evaluate the anatomy of the internal cerebral vein and its primary tributaries and classify them depending on their course patterns using CTA. The study was performed using a multidetector row CT scanner (Optima CT 660; GE Healthcare, Milwaukee, Wisconsin), and a nonionic contrast agent iomeprol (70 mL administered; Iomeron 350; 350 mg iodine/mL; Bracco Imaging, Milan, Italy) was injected. The ASV–ICV junction usually was located at the foramen of Monro (57.2%). The malignant lymph nodes may get stuck to the internal jugular vein and the surgeon has to then resect a portion of the vein. A, The suprathalamic LDV (type 2; left hemisphere).

Identification of the major tributary of the ICV is of immense importance because a surgical occlusion or an injury to the vein draining the basal ganglia may result in a venous infarction.13. As the LDV takes over the area the TSV usually drains, the TSV may be insufficiently developed when it is present.6,7. The statistical analysis was conducted with SPSS, Version 25, 2000–2016 (IBM, Armonk, New York). The purpose of this study was to explore the anatomic variation and quality of TSV and its smaller tributaries … • ICVs, VofG, and tributaries drain ovoid area surrounding lateral/3rd ventricles. 36.1 In this patient with a tentorial incisura meningioma (a–c; T1-weighted postcontrast MRI), the major question to be answered before surgical removal is whether the straight sinus is functional and, if not, how the deep brain drains, as this will determine which veins to spare during surgery and which approach to take. Additional drainage of the basal vein of Rosenthal (7) in the present case is through the inferior temporal vein (8). Type 1 is present in the left hemisphere. C, The retrothalamic LDV (left hemisphere). No statistically significant differences were found between the number of TSVs present and the hemispheres in the sample overall (P = .82), in the male patients (P = .27), in the female patients (P = .57), or while comparing the variant presence of the TSV in the different hemispheres and the sexes combined (P = .82). CONCLUSIONS: Detailed knowledge of the anatomy of the deep cerebral veins is of great importance in neuroradiology and neurosurgery because iatrogenic injury to the veins may result in basal nuclei infarcts. In type 1, only the thalamostriate vein collects blood from the basal nuclei. 3.0” grant for the young researchers to assist with costs of international competitions and conferences. Special consideration was given to the size and location of drainage of the vein of Galen and its tributaries. The course of the lateral direct vein and its influence on the number of thalamostriate veins and their diameters and courses were assessed. The internal cerebral veins unite with the basal veins (of Rosenthal) to form the great cerebral vein (of Galen) just beneath the splenium of the corpus callosum in the quadrigeminal cistern. Two MRA studies found type IA in 53.9% and 63.4% of hemispheres,11,14 while a cadaveric study found it in 52.2% of the hemispheres.3 Furthermore, our study revealed that nearly half of the patients (48%) had an ASV–ICV junction asymmetry between 2 hemispheres. The vein that accompanies the internal iliac artery; it merges with the external iliac vein to form the common iliac vein. A 64-year-old woman presented with seizures and progressive headaches. Numerous researchers have reported differences in internal cerebral vein … Internal jugular vein acts as a guide for surgeons during removal of deep cervical lymph nodes. An operation on the third ventricle poses a major challenge for neurosurgeons because it is surrounded by vital neural and vascular structures. The primary tributary of the ICV is either the TSV or the LDV. In the total research material, we observed the following number of ASVs present: no ASV present in 3 hemispheres (3 on the right side), 1 present (the most common) in 464 hemispheres (234 right and 230 left hemispheres), 2 present in 32 hemispheres (13 right, 19 left), and last, the least common, 3 ASVs in just 1 hemisphere (left). Tentorial incisura meningioma with occlusion of the straight sinus and rerouting of the deep venous drainage. The exclusion criteria included the following: hydrocephalus; cerebral lesions (intracranial hematoma, tumors, vascular malformations); posttraumatic, postsurgical, and poststroke defects that affect the presence and course of the veins; significant imaging artifacts (such as low quality or illegible images); postcraniotomy state; and incomplete cross-sections. It is vital to explore detailed anatomic characteristics of all the tributaries of the ICV, especially the LDV, because a surgical strategy may require altering when it is present. The drainage territory is highly variable and it usually directly drains the colliculi and receives numerous tributaries: callosal veins; superior (Galenic) group. We found that the TSV alone was the main ICV tributary draining the striatum in 77% of the hemispheres; therefore, we considered this pattern the normal anatomy (type 1). The callosal veins that drain the corpus callosum. Our study concluded that the anterior location of the ASV–ICV junction (type IA: 58.8% of the hemispheres) is more common than its posterior location (types IB + IIA + IIB: 40.4% of the hemispheres). A classification of internal cerebral vein branching patterns may aid clinicians in planning approaches to the third and lateral ventricles. Type III, ASV absent, was found only in 2 hemispheres (both on the right side). Last, no statistically significant differences were found in the combined analysis of sex, hemisphere, and type (P = .25). The internal cerebral vein runs in the roof of the third ventricle. Future studies should attempt to investigate the morphometric lengths of the veins to enhance patient outcomes. MATERIALS AND METHODS: Head CTAs of 250 patients were evaluated in this study, in which we identified the number and termination of the anterior septal vein and the lateral direct vein. Detailed anatomic knowledge of both the normal and variant anatomy of the ICV branching patterns is crucial to develop optimal surgical strategies to access the third and lateral ventricles, and the large number of diagnostic head studies available currently allows us to conduct an assessment of anatomic variations on a great number of subjects. The remaining 250 patients were included in this study, of whom 84 were men (33.6%) and 166 were women (66.4%).

We classified ICV tributaries into 4 types, depending on the main veins draining the basal nuclei (Fig 2). As the ICV goes posteriorly, small subependymal veins and the posterior septal veins join it; just inferior to the splenium of the corpus callosum, the paired ICVs join the paired BVR to form the VG (see above). The internal cerebral vein (ICV), together with the basal vein of Rosenthal and their tributaries, form the deep cerebral venous system. BACKGROUND AND PURPOSE: The internal cerebral vein begins at the foramen of Monro by the union of the thalamostriate and the anterior septal veins. Case continued in. A thorough preoperative understanding of the variation in the patterns of deep cerebral veins may help reduce the risk of iatrogenic injury to those vessels. In type III, the ASV is absent. 1 Other major tributaries that join the ICV include the lateral direct vein (LDV) and the medial atrial vein. No statistically significant differences were found between the number of ASVs present and the hemispheres in the sample overall (P = .16), in the male patients (P = .27), in the female patients (P = .36), or while comparing the variant presence of the ASV in the different hemispheres and both sexes (P = .16). Special consideration was given to the size and location of drainage of the vein of Galen and its tributaries. The data were analyzed on a dedicated workstation (Advantage Workstation AW4.5; GE Healthcare) equipped with software for MIP and 3D volume-rendering postprocessing of images. Outside computed tomography revealed a large mass centered at the tentorial incisura, and she presented to neurosurgery. The deep cerebral veins have received little attention in comparison with the cerebral arteries. Most of the blood in the deep … Fig. The presence of the LDV located above or behind the thalamus characterizes types 2 and 3, respectively. Type IA predominated in both men (50% of the right and 54.76% of the left hemispheres) and women (63.25% of the right and 56.02% of the left hemispheres). of the thalamostriate vein (the main terminal tributary of the internal cerebral vein) involves periventricular white matter from the caudate area to the level of the upper half of the atri-um. Research on the anatomy of the deep veins around the vein of Galen (VG) is very important and has valuable clinical significance. Case continued in, Right internal carotid artery injection lateral (a) and AP (b) in the venous phase demonstrates drainage of the ICVs, rather than in the vein of Galen, craniomedially into two medial parietal veins (2) toward the superior sagittal sinus. The superficial group drains the cortical surfaces. No statistically significant differences were found between the type of ASV–ICV junction present and the hemispheres in the sample overall (P = .12), in the male patients (P = .06), in the female patients (P = .28), or while comparing the variant presence of the ASV–ICV junction on the different hemispheres and sexes combined (P = .12). Coronal MR venography (d) with sagittal reconstructions (e) suggests occlusion of the vein of Galen with a straight sinus stump (1), persistence of a left-sided tentorial sinus (2), superior drainage into a medial parietal vein (3), and anterior drainage of the right basal vein of Rosenthal (4). It’s created by the union of 2 internal cerebral veins below and behind the splenium of corpus callosum. A 64-year-old woman presented with seizures and progressive headaches.
