Abstract:
OBJECTIVESTo study the revascularization techniques in the treatment of intracranial complex aneurysms and occlusive reasons of bypass vessel.
METHODSThe 20 complex intracranial aneurysms who underwent saphenous bypass treatment from November 2006 to November 2008 were retrospectively analyzed and the occlusive reasons were studied. Of the 20 patients, 12 were female and 8 were male, mean age was 54.5 years (ranged 27 - 65 years). The distribution of the lesions included 13 cavernous sinus aneurysms, 4 para-clinoid aneurysms, 2 supraclinoid aneurysms, and 1 basilar trunk aneurysm. Four aneurysms were giant (diameter > 25 mm), 12 aneurysms were large (15 - 25 mm), and 4 aneurysms were medium (10 - 15 mm) size.
RESULTSOne saphenous vein was occluded intraoperatively and one saphenous vein was occluded postoperatively. At discharge, 18 out of the 20 patients had Glasgow Outcome Scale (GOS) score of 4 or 5, 2 patients had score of 3, and 1 patient had score of 1. At 6 months follow up, 18 of 19 survivors had GOS score of 4 or 5 and 1 patient had score of 3.
CONCLUSIONSExtracranial-intracranial revascularization technique is a safe and effective method in the treatment of complex aneurysms. Mechanical and hemodynamic factors are two leading reasons for occlusion of bypass vessels. Long-term bypass vessels patent rate still needs further observation.
