Treatment strategies for dissecting aneurysms of the posterior cerebral artery.

摘要: Dissecting aneurysms of the posterior cerebral artery (PCA) are rare and difficult to treat because their deep unfamiliar locations unusual shapes. Although several treatment modalities have been proposed, none generated satisfying results. Our experiences with PCA-dissecting reviewed strategies discussed. All consecutive patients aneurysm who were treated in a tertiary referral hospital between January 1998 March 2014 identified by retrospective review. Their clinical characteristics, radiological findings, outcomes documented. Of 21 aneurysms, 9 had subarachnoid hemorrhage 3 acute infarction thalamus at presentation. The involved P1 (n = 4), P1–2 junction (n = 3), mid-P2 (n = 6), P2A P2P (n = 1) P2-3 (n = 4). shapes as follows: fusiform (n = 12), partially thrombosed (n = 8) blood blister-like (n = 1). mean size was 16.6 ± 9.7 mm. Parent occlusion (PAO) without bypass (n = 15), PAO (n = 2), stent-assisted endosaccular coiling (n = 3) stent placement only performed. three underwent single patient developed recurrence. Six ten received balloon test (BTO) experienced PCA territory infarction, whereas one five after passing BTO an infarction. for effective preventing In addition, before helpful identifying candidates truly needed surgical revascularization.
