Clinical and angiographic follow-up of ruptured intracranial aneurysms treated with endovascular embolization.

摘要: BACKGROUND AND PURPOSE: Endovascular embolization is a well-established treatment of ruptured intracranial aneurysms, but concern about its long-term stability and ability to prevent rehemorrhage are still present. We evaluated the clinical angiographic follow-up patients with cerebral aneurysms treated coiling, focusing on changes in aneurysm morphologic features. MATERIALS METHODS: A total 377 that were endovascular approaches at our institution between 1994 2008 reviewed. Clinical data analyzed from prospectively collected base. RESULTS: There 391 for 14 years. Good outcome (Glasgow Outcome Score [GOS], 5) was achieved 74% patients, moderate disability or poor 18%, 8.8% died. Permanent morbidity mortality procedural complications occurred 2.9%. Complete available 85% surviving mean 22.3 months. Re-treatment required 11% (31 patients). Eight (2.1%) had rebleeding, 6 (1.6%) hospital within 30 days treatment, 5 first 48 hours. Follow-up imaging 276 270 patients. Recanalization 56 (20.3%) regardless initial result, risk higher if body remnant left (χ2, 11.791; P = .0006). CONCLUSIONS: Long-term demonstrates efficacy aneurysms. Rebleeding after rare, greatest during hours treatment. Initial results not useful predictor rehemorrhage.
