Abstract:
Objective To investigate the effect of parent artery occlusion with liquid embolic agents (Onyx)for the treatment of distal intracranial aneurysms. Methods The clinical data of 27 patients with 29 ruptured distal intracranial aneurysms were analyzed retrospectively.Seventeen aneurysms located in the posterior inferior cerebellar artery,3 in the anterior inferior cerebellar artery,2 in the superior cerebellar artery,2 in the posterior cerebral artery,1 in the anterior cerebral artery,and 4 in the middle cerebral artery.Twenty-eight aneurysms were treated with Onyx to occlude proximal parent arteries and aneurysms, and 1 distal middle cerebral artery aneurysm was occluded spontaneously. Results All the aneurysms treated were occluded completely.One patient died of intraoperative hemorrhage.The remaining patients were followed up for 8 to 67 months.The final Glasgow outcome scale (GOS)scores were 5 in 23 patients and 4 in 3 patients. 17 patients were followed up with digital subtraction angiography (DSA)and 5 were followed up with computed tomography angiography (CTA)after procedure.There was no recurrence of the aneurysm. Four patients were followed up clinically.No new neurological disturbance or rebleeding was found in all the survived patients. Conclusion Medium-long term follow-up results have shown that the clinical efficacy of proximal parent artery occlusion with Onyx for the treatment of distal intracranial aneurysms is satisfactory,and the recurrence rate is low.
