BACKGROUND Aneurysms of the internal carotid artery(ICA)bifurcation are rare,and no studies have compared patient outcomes after endovascular vs surgical treatment.OBJECTIVE To report the safety,efficacy,and follow-up outcome of these 2treatment options for patients with ICA bifurcation aneurysms.METHODS Patient and aneurysm characteristics,treatment results,and follow-up outcomes(at 30 months)were analyzed from patient records and review of imaging findings.RESULTS A total of 58 patients with ICA bifurcation aneurysms were treated.By interdisciplinary consensus,30 aneurysms were assigned for coiling and 28 for clipping.Patients who underwent surgical clipping were younger and had larger aneurysms.More patients were assigned to coiling if their aneurysms originated only from the ICA bifurcation or projected superiorly.For the combined angiographic endpoint,complete and nearly complete occlusion(Raymond-Roy I+II),similar rates of 96%(coiling)or 100%(clipping)could be achieved.Raymond-Roy I occlusion occurred more often after clipping(79%vs 41%coiling).Follow-up of the endovascular group showed minor recanalization of the aneurysm neck(Raymond-Roy II)in 42%.One patient(4%)showed a major recanalization(Raymond-Roy III)and needed retreatment.For incidental findings,no bleeding complications or new persistent neurological deficits occurred during follow-up.CONCLUSION Treatment of ICA bifurcation aneurysms after interdisciplinary assignment to clipping or coiling is effective and safe.Despite significantly more minor recanalizations after coiling,the re-treatment rate was very low,and no bleeding was observed during follow-up.Multivariate analysis revealed that origin only from the ICA bifurcation was an independent predictor of aneurysm recanalization after endovascular treatment.
