PURPOSE: The purpose of this study is to report mid- and long-term clinical and angiographic results of coiling of basilar tip aneurysms. MATERIALS AND METHODS: Between January 1995 and August 2006, 154 basilar tip aneurysms were coiled. A total of 114 (74%) had ruptured and 40 (26%) were unruptured. There were 42 men and 112 women taking part in this study, with a mean age of 50.5 years (median, 50; range, 25-73 years). The mean aneurysm size was 11.1 mm (median, 10; range, 2-30 mm) and 71 (46%) were large or giant. Of 154 aneurysms, 40 (26%) were primarily coiled with a supporting device. RESULTS: Initial occlusion was (near) complete in 144 (94%) and incomplete in 10 (6%) aneurysms. The combined procedural mortality and morbidity was 3.8% (6 of 154, 95% CI 1.4-8.3%). The mean clinical follow-up of 144 surviving patients was 53 months (range, 3-144 months; 637 patient-years). The annual incidence rate for recurrent haemorrhage was 0.3% (2 in 637 patient years, 95% CI 0.04-1.1%). During angiographic follow-up of mean 34 months (range, 6-122 months) in 138 patients (96%), 27 basilar tip aneurysms (17.5%) re-opened over time and were additionally coiled. Of these, 11 repeatedly re-opened and were repeatedly coiled. An aneurysm size of median >10 mm was the only significant predictor for re-treatment at follow-up (OR 7.0, 95% CI 2.5-19.7). CONCLUSION: Coiling of basilar tip aneurysms is safe and effective in preventing recurrent haemorrhage. Follow-up angiography is mandatory to timely detection of re-opening, especially in large and giant aneurysms.
