Characteristics and surgical treatment of dolichoectatic and fusiform aneurysms

摘要: Dolichoectatic and fusiform aneurysms represent a small subset of cerebral are often among the most difficult to treat. A consecutive series 40 patients with 41 these two types is presented, including their clinical characteristics surgical treatments. Common all was pathological involvement length blood vessel separate inflow outflow sites (nonsaccular). However, dolichoectatic have markedly different symptoms treatments depending on location in either anterior or posterior circulation. Anterior circulation involved petrous internal carotid artery (ICA) one, supraclinoid ICA three, middle 13, four patients. Posterior basilar vertebral six, inferior cerebellar one patient. Various procedures were performed, direct clipping, trapping bypass, proximal occlusion, resection reanastomosis, transposition, aneurysmorrhaphy thrombectomy, wrapping. There no mortality patient series, treatment effective many Overall, outcome at late follow up good (Glasgow Outcome Scale scores 1-2) 78% Patients had better outcomes than aneurysms, 90% 65% cases, respectively. giant serpentine may develop from smaller spectrum same entity. Arterial dissection also play role initial development aneurysms.
