Long-term follow-up studies after endovascular treatment for @entity438 are still rare and inconclusive. The aim of this study was to assess long-term clinical and angiographic outcome of @entity1 with endovascularly treated @entity439 . The Clinical outcome of all 185 @entity1 with endovascularly treated @entity439 were analyzed and 77 out of 122 surviving @entity1 were examined with MRI and MRA nine to 16 years (mean 11 years) after the initial endovascular treatment. Sixty-three @entity1 were deceased at the time of follow-up. The cause of @entity204 was @entity439 -related in 34 (54%) @entity1 . The annual rebleeding rate from the treated @entity439 was 1.3% in the ruptured group and 0.1% in the unruptured group. In long-term follow-up MRA 18 @entity439 (53%) were graded as complete, 11 @entity439 (32%) had neck remnants and five @entity439 (15%) were @entity2300 in the ruptured group. Occlusion grade was lower in the unruptured group with 20 @entity439 (41%) graded as complete, 11 (22%) had neck remnants and 18 (37%) were incomplete. However, only three @entity439 were unstable during the follow-up period and needed retreatment. Endovascular treatment of unruptured @entity439 showed incomplete angiographic outcome in 37% of cases. However, @entity548 rate was as low as 0.1%. Endovascular treatment of @entity1756 showed incomplete angiographic outcome in 15% of cases and the annual rebleeding rate was 1.3%.
