BACKGROUND: Flow diverters have emerged as a major tool in the treatment of cerebral aneurysms. A crucial issue with the use of flow diverters is the patency of side branches covered by the device, most importantly the ophthalmic artery (OA). OBJECTIVE: To assess the patency of the OA after coverage with the pipeline embolization device (PED). METHODS: All patients who had a PED covering the OA and in whom angiographic follow-up was available were included in the study. The patency of the OA at follow-up was systematically evaluated by 2 authors who were not involved in the procedure. RESULTS: Of 95 treated patients, the OA was covered by 1 PED in 81 patients (85%) and by 2 PEDs in 14 patients (15%). Mean angiographic follow-up was 7.5 months, ranging from 3 to 24 months. At the latest follow-up, the OA remained patent in 85 patients (89%), showed diminished flow in 4 patients (4%), and was occluded in 6 patients (7%). Only 1 patient had clinical symptoms related to OA occlusion. In multivariable analysis, larger aneurysm size predicted OA occlusion (P = .04). There was also a strong trend for younger age (P = .06) and coverage by more than 1 device (P = .07). CONCLUSION: Treatment of internal carotid artery aneurysms with the PED preserves the patency of the OA in most cases. The occlusion of the OA in the few cases where it occurs is usually a clinically irrelevant event. Minimizing the number of PEDs across the OA is crucial to preserve its patency.
