The aim of this study was to evaluate the safety and effectiveness of 1-stage coiling for multiple intracranial aneurysms. MATERIALS AND METHODS: All patients who underwent 1-stage coiling for >=2 aneurysms were identified from a prospectively registered neurointerventional data base during 10 years. The patient characteristics and clinical and angiographic outcomes at discharge and follow-up were retrospectively evaluated. RESULTS: One hundred sixty-seven patients (male/female ratio, 30:137; mean age, 58 years) with multiple aneurysms (418 aneurysms; mean, 2.5 aneurysms/patient) underwent attempted 1-stage coiling for >=2 aneurysms (359 aneurysms; mean, 2.1 aneurysms/patient). In 131 patients (78.4\%), all detected aneurysms were treated with coiling only. Treatment-related morbidity and mortality at discharge were 1.8\% and 0.6\% per patient, respectively. Of the 132 patients without subarachnoid hemorrhage, 129 (97.7\%) had favorable outcomes (mRS 0{\textendash}2) at discharge; of the 35 patients with SAH, 27 (77.1\%) had favorable outcomes at discharge. Of the 162 patients (97\%) for whom clinical follow-up was available (mean, 35.8 months), 154 patients (95.1\%) had favorable outcomes. Immediate posttreatment angiography showed complete occlusion in 186 (51.8\%) aneurysms, neck remnants in 134 (37.3\%), sac remnants in 33 (9.2\%), and failure in 6 (1.7\%). Of the 262 (73.9\%) aneurysms that underwent follow-up imaging (mean, 24.8 months), 244 (93.1\%) showed a stable or improved state, with 12 (4.6\%) minor and 6 (2.3\%) major recurrences. CONCLUSIONS: One-stage coiling of multiple aneurysms seems to be safe and effective, with low morbidity and mortality.}, issn = {0195-6108}, URL = {https://www.ajnr.org/content/35/6/1170}, eprint = {https://www.ajnr.org/content/35/6/1170.full.pdf}, journal = {American Journal of Neuroradiology} }
