Progressive occlusion of aneurysms in stent-assisted coiling of ruptured wide-necked intracranial aneurysms [Kanamış geniş-boyunlu İntrakranyal anevrizmalarda stent-yardımlı koilleme ile anevrizmaların İlerleyici oklüzyonu]

Objectives: the aim of our study was to determine whether stent assisted coiling may promote progressive occlusion of an incompletely occluded aneurysm.methods: from march 2009 to december 2012,177 patients with ruptured wide-necked aneurysms (58 patients in the stent group and 109 in the nonstent group) treated by endovascular coiling were retrospectively enrolled. all patients included in this study had follow up angiographic results. enterprise stents were used for coiling in the stent group. simple coiling and balloon-assisted coiling technique were used for coiling in the nonstent group. no significant difference in patient demographics and aneurysmal characteristics (patient age,aneurysm diameter,neck size,and dome-to-neck ratio) were observed between the 2 study groups. angiographic follow-up results for stented and nonstented aneurysms were compared.results: with a mean follow-up time of 8 month,progressive occlusion rates was significantly higher in the stent group (16/29,55.2%) than in the nonstent group (10/34,29.4%)(p=0.03). recurrence rate was not significantly different between two groups (13.8% (8/58) in the stent group compared with 17.4% (19/109) in the nonstent group) (p=0.54).conclusion: we conclude that enterprise stent-assisted coiling significantly promotes progressive occlusion of incompletely occluded aneurysms at initial treatment compared with nonstent-assisted coiling. © 2014,ege university press. all rights reserved.
