Abstract Understanding the anatomy of the anastomotic veins (AV) of the superficial cortical venous system (SCVS), viz. superficial Sylvian vein (SSV) - also known as the superficial middle cerebral vein; vein of Labbe (VL) and vein of Trolard (VT), are imperative for neurosurgical procedures. This study aimed to investigate variant anatomical patterns of dominance of the AV, to elucidate the haemodynamically balanced SCVS, by reporting variations between the presence, diameter and dominant patterns of the AV. Two hundred lateral angiograms were included, depicting left and right cerebral hemispheres of the same patient (n = 100 patients). Angiograms were analysed and variations recorded. Results were statistically compared against laterality, age, sex and ethnicity. Presence of the VL had the highest occurrence (96.5%), whereas the SSV and VT had an occurrence of 75.5% and 64.5%, respectively. This study reports presence of double veins of the AV: SSV (12.0%), VL (22.0%) and VT (19.5%). Furthermore, presence of a triple vein for each AV is reported. Diameters for the SSV, VL and VT were 1.99 ± 0.500mm, 2.18 ± 0.579mm and 2.14 ± 0.472mm, respectively. Statistically significant relationships were established between diameters and the SSV, VL, VT and VT2 (double VT). Seven types of dominant patterns were recorded: Equilibrium; singular dominance of SSV, VL and VT; co-dominance of SSV/VL, SSV/VT and VL/VT. The Equilibrium dominant pattern of drainage had the highest occurrence (54.5%). Patterns of dominance of these AV can aid the neurosurgeon in curbing the risk of iatrogenic injury and postoperative infarcts even after an otherwise successful surgery.

Abstract The microsurgical anatomy of the deep venous system of the brain was examined in 20 cerebral hemispheres. The deep venous system is composed of the internal cerebral, basal, and great veins and their tributaries. This system drains the deep white and gray matter surrounding the lateral and 3rd ventricles and the basal cisterns. The deep veins are divided into a ventricular group composed of the veins converging on the walls of the lateral ventricles and a cisternal group that includes the veins draining the walls of the basal cisterns. The internal cerebral vein is included in the ventricular group because it is predominantly related to the ventricles, and the basal and great veins are reviewed with the cisternal group because they course through the basal cisterns. The choroidal veins are included with the ventricle veins because they arise on the choroid plexus in the ventricles. The thalamic veins appear in both the ventricular and the cisternal groups because some course on the ventricular surfaces and others course in the basal cisterns. The operative approaches to the major trunks in this system are reviewed.

Careful Navigation

Endovascular treatment of carotid cavernous fistulas (CCFs) via a transvenous approach is standard, but in rare cases this approach is challenging due to absence or thrombosis of the commonly used venous routes. A 61-year-old woman presented with a symptomatic CCF with all but one of the venous access routes to the CCF thrombosed, leaving an engorged superficial middle cerebral vein (SMCV) as the only venous outflow from the cavernous sinus. Access to the CCF was made possible after careful navigation of the sigmoid sinus, the vein of Labbé and the SMCV, bypassing the need for surgical access to the SMCV or for a direct transorbital puncture. The CCF was completely occluded by coiling and Onyx embolization. The patient made an uneventful recovery, with resolution of her symptoms. To the best of our knowledge, this access route has not been previously reported in the treatment of CCFs.

Using Data

In a number of earlier reports significant relationships were found between latency measures of the cortical average evoked response (AER) and measures of human intelligence. Previous studies have also shown significant relationships between various AER frequency measures and intelligence. Using data from a study in which a significant AER latency-intelligence correlation was obtained, we failed to find a correlation between AER frequency measures and intelligence. However, significant correlations were obtained between AER latency measures and certain frequency measures. The results also indicate that the frequency measures for AERs between left and right cerebral hemispheres are highly reliable.

Vascular Variant

AbstractThe occipitotemporal vein (OTV) courses over the temporal lobe, connecting the superficial middle cerebral vein and the transverse sinus. This vein is rarely identifiable on computerized tomography (CT) scans and a large amount of contrast is needed to identify such a relatively small vessel. We present a 12-month-old male with acute coalescent mastoiditis and a subperiosteal abscess. An epidural abscess was suspected on pre-operative CT scan. No abscess was found on surgery. Based on the surgical finding, we determined that this misdiagnosis was due to a vascular variant, the occipitotemporal vein (vein of Labbe) that masqueraded as an abcess on the CT scan. Recognition of the vein of Labbe on CT scan is therefore essential for the appropriate management of otological and neurotological disease.

Abstract BACKGROUND AND IMPORTANCE: High-grade cavernous sinus (CS) dural arteriovenous fistulae with cortical venous drainage often have a malignant presentation requiring urgent treatment. In the absence of a venous access to the lesion, transarterial embolization can potentially cure these lesions; however, the high concentration of eloquent arterial territories adjacent to the fistula creates a precarious risk of arterial-arterial reflux. In such cases, a combined surgical and endovascular approach may provide the least invasive option. CLINICAL PRESENTATION: We describe a patient presenting with a venous hemorrhagic infarct caused by a high-grade CS dural arteriovenous fistula (Barrow type D caroticocavernous fistula) with isolated drainage via the superficial middle cerebral vein into engorged perisylvian cortical veins. No transfemoral or ophthalmic strategy was angiographically apparent, and the posterior location of the involved CS compartment mitigated a direct puncture. The patient underwent direct puncture of the superficial middle cerebral vein via an orbitozygomatic craniotomy and the CS was catheterized under fluoroscopic guidance. The CS was coil-embolized back into the distal superficial middle cerebral vein with complete obliteration of the fistula. The patient did well with no new deficits and made an uneventful recovery. CONCLUSION: This novel combined open surgical and endovascular approach enables obliteration of a CS dural arteriovenous fistula with isolated cortical venous drainage and avoids the additional manipulation with direct dissection and puncture of the CS itself.

Spgr Sequence

The termination of the superficial middle cerebral vein (SMCV) has been described as entering or being partially equivalent to the venous sinus coursing under the lesser sphenoid wing, which has classically been called the sphenoparietal sinus. However, the recent literature reports that the SMCV is not connected to the sphenoparietal sinus. In this study, the venous anatomy was evaluated to clarify the anatomy of the sphenoparietal sinus and the termination of the SMCV. Magnetic resonance imaging (MRI) was performed on 1.5-T superconductive units using a three-dimensional fast spoiled gradient-recalled acquisition in the steady state (3-D fast SPGR) sequence with fat suppression in a total of 48 sides of 24 patients. Coronal source images and reconstructed axial images were displayed on the Advantage Window Console, and connections to the cavernous sinus were then evaluated for the venous sinus coursing under the lesser sphenoid wing (hereafter called the sinus of the lesser sphenoid wing), the middle meningeal vein, and the SMCV. The following findings were observed bilaterally in all patients. The sinus of the lesser sphenoid wing was connected medially with the cavernous sinus and laterally with the anterior branch of the middle meningeal vein near the pterion. The anterior branch of the middle meningeal vein entered the bony canal laterally above the junction with the sinus of the lesser sphenoid wing and coursed along the inner table of the skull or emerged into the diploic vein, indicating its parietal portion. Although the termination of the SMCV had several patterns, the SMCV was not connected with the sinus of the lesser sphenoid wing in any of the patients. The sphenoparietal sinus is considered to consist of the sinus of the lesser sphenoid wing and the parietal portion of the anterior branch of the middle meningeal vein; these were identified as venous structures distinct to the SMCV.
