摘      要：Backgroud:We aimed to evaluate the clinical presentations and report the acceptable clinical and angiographic outcome of the distal posterior cerebral artery (PCA) dissecting aneurysms with parent artery occlusion (PAO).Methods:From June 2006 to July 2013,26 patients with PCA dissecting aneurysms were planned to be treated via endovascular PAO in our *** patients had ruptured aneurysms,and twelve patients had unruptured *** endovascular modalities were the following:1) PAO (n =19),2) palliative embolization (n =5),and 3) proximal PAO (n =2).Glasgow Outcome Scale (GOS) was used to assess the clinical ***:The procedure was technically successful in all *** the PAO and proximal PAO group,all of the immediate angiography showed occlusion of the parent vessel,and follow-up imaging showed no recurrence of the *** the palliative embolization group,one of five patients was died of rebleeding after the procedure,and follow-up digital subtraction angiography (DSA) showed the other four aneurysms *** procedure related complications occurred totally:rebleeding (n =1),hemiparesis (n =2),and hemianopsia (n =2).Conclusion:Dissecting aneurysms are dynamic lesions with variable and unpredictable evolution and a thorough treatment is *** the parent artery appears to be well tolerated for distal segment of *** propose that this technique could be the first treatment option in treating dissecting aneurysms in this ***,palliative occlusion of distal PCA dissecting aneurysms is not an advisable treatment option.
