Superficial Sylvian veins as landmarks for operation of middle cerebral artery aneurysms.
نویسنده
چکیده
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.

Incidence 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 کاملDepicting cerebral veins by three-dimensional CT angiography before surgical clipping of aneurysms.
BACKGROUND AND PURPOSE Cerebral veins show wide variation, and unexpected veins occasionally limit surgical procedures for clipping of cerebral aneurysms. This study was undertaken to assess the utility of three-dimensional CT angiography (3D-CTA) in the evaluation of venous anatomy before surgical clipping of cerebral aneurysms. METHODS 3D-CTA was performed in 19 patients before pterional cr...

PURPOSE The purpose of this study was to introduce a method of using three-dimensional (3D) curved-multiplanar reconstruction (MPR) images for sylvian dissection during microsurgical treatment of middle cerebral artery (MCA) aneurysms. MATERIALS AND METHODS Forty-nine patients who had undergone surgery for MCA aneurysms were enrolled. We obtained the 3D curved-MPR images along the sphenoid ri...

OBJECTIVE This study proposes more objective methods for deciding the appropriate direction of the sylvian fissure dissection during surgical clipping in middle cerebral artery (MCA) bifurcation aneurysms. METHODS We reviewed data of 36 consecutive patients with MCA bifurcation aneurysms. We measured 2 indices preoperatively on 3-dimensional computed tomography angiography (3D-CTA). Analysis ...
