Variations of the superficial middle cerebral vein: classification using three-dimensional CT angiography.
BACKGROUND AND PURPOSE Classification of variations of the superficial middle cerebral vein (SMCV) remains ambiguous. We propose a new classification system based on embryologic development for preoperative examination. METHODS Three-dimensional CT angiography was used to evaluate 500 SMCVs (in 250 patients). The outflow vessels from the SMCV were classified into seven types on the basis of e...
متن کاملIncidence of superficial sylvian vein compromise and postoperative effects on CT imaging after surgical clipping of middle cerebral artery aneurysms.
BACKGROUND AND PURPOSE Dissection and retraction of the sylvian fissure can cause venous insufficiency and may be an important contributor to postoperative edema or hemorrhage after clipping of a middle cerebral artery (MCA) aneurysm. The incidence of changes in the superficial middle cerebral vein (SMCV) and adjacent veins and whether such changes increase the amount of edema or hemorrhage on ...
متن کاملDural arteriovenous fistula between inferolateral trunk of the internal carotid artery and superficial sylvian vein.
A 40-year-old Brazilian man presented with headache followed by consciousness disturbance. Computed tomography showed subarachnoid hemorrhage with right frontal hematoma. Angiography revealed a dural arteriovenous fistula (dAVF) fed by the inferolateral trunk of the internal carotid artery and draining into the superficial sylvian vein with varix formation. The shunting point was directly oblit...
متن کاملIsolated Superficial Sylvian Vein Thrombosis with Long Cord Sign: Case Report and Review of the Literature
Isolated cortical vein thrombosis (ICVT) is extremely rare. Only single case or small series of ICVT have been reported; clinical details are still uncertain. We report a case of isolated superficial sylvian vein thrombosis with exceedingly long cord sign. A 14-year-old female with severe sudden onset headache visited our hospital. Fluid attenuated inversion recovery and echo-planar T2(*) susce...
متن کاملSuperficial Sylvian veins as landmarks for operation of middle cerebral artery aneurysms.
A retrograde approach to aneurysms located at the middle cerebral artery bifurcation which uses the superficial Sylvian veins as landmarks is described. Fifty patients with 51 aneurysms were operated on using this technique. This method made it easier for surgeons to decide where to enter the Sylvian fissure for dissection of the middle cerebral artery branches and to secure the parent artery.
