OBJECTIVE: To analyze the immediate and midterm angiographic and clinical results of stent placement in the endovascular treatment of @entity438 . METHODS: Out of 330 @entity438 treated by endovascular approach in our neurovascular centre, stents have been used in 18 @entity1 . Twelve @entity439 (66.7%) were acutely ruptured, four (22.2%) were unruptured, two (11.1%) were recanalized after initial coiling. In three @entity1 (16.7%) stent placement was used for revascularization of acute vessel @entity715 during coiling. Angiographic follow-up was obtained in 13 (72.2%) @entity1 (mean 1.8 years, range 0.4-6.6) and clinical follow-up in 13 (72.2%) @entity1 (mean 2.0 years, range 0.2-6.6). RESULTS: Complete occlusion was achieved in eight (44.4%) @entity1 , a neck-remnant remained in four (22.2%) and an incomplete occlusion in four (22.2%). In the two cases of previously treated @entity439 a neck-remnant remained after secondary stent-assisted coiling. In four cases @entity1031 events resulted in a transient procedure related morbidity. No permanent procedure related morbidity or mortality was observed. One case of an asymptomatic late in-stent @entity850 occurred. On clinical followup modified Ranking Score was 0 in 3 @entity1 (23.1%), 1 in 3 @entity1 (23.1%) and 2-3 in 7 @entity1 (53.9%). On angiographic follow-up recanalisation was observed in 5 (38.5% = 5/13) @entity439 . CONCLUSION: Even in acutely @entity1756 , stent assisted coiling can be a relatively effective and safe treatment for @entity438 . One asymptomatic in-stent @entity850 occurred indicating that the risk rate of @entity256 seems to be lower compared to stent deployment in @entity731 , where @entity256 rates up to 30% are described.
