Clinical analysis of endovascular interventional treatment of intracranial peripheral aneurysms / 中国脑血管病杂志

ABSTRACT

Objective To investigate the clinical effect of endovascular interventional treatment of intracranial peripheral aneurysms. Methods From January 2013 to December 2016,the clinical data of 31 patients with intracranial peripheral aneurysm admitted to the Department of Neurosurgery,Anhui Provincial Hospital were analyzed retrospectively.Among them,12 patients had saccular aneurysms,10 had narrow-neck aneurysms,and 2 lacked clear aneurysm necks;19 patients had fusiform aneurysms,they all lacked clear aneurysm necks.Ten patients with narrow-neck saccular aneurysm were treated with coil embolization, of the 2 lacked clear neck saccular aneurysms,1 was treated with stent-assisted coil embolization,1 was treated with coil occlusion of the aneurysm and parent artery;4 patients with fusiform aneurysm were treated with coil occlusion of the aneurysms and parent arteries,11 with fusiform aneurysm were treated with Onyx glue occlusion of the aneurysms and parent arteries,and 4 with fusiform aneurysm were treated with coils in combination with Onyx glue occlusion of the aneurysms and parent arteries.They were followed up for 6 to 36 months after procedure. Results All patients were successfully treated with endovascular intervention,no rebleeding cases were found.Immediate postoperative angiography showed that 11 patients with saccular aneurysm were totally occluded.The aneurysms and parent arteries in 1 patient with saccular aneurysm and 19 with fusiform aneurysm were totally occluded.The aneurysms and parent arteries of 8 patients were occluded with Onyx glue,cranial CT revealed different degrees of cerebral infarction (6 patients without new neurological deficits,2 new neurologic deficits).CT revealed cerebral infarction in 1 patient treated with coils in combination with Onyx glue for occlusion of the aneurysm and parent artery(no new neurologic deficit),other patients did not have cerebral infarction and new neurologic deficits.DSA follow-up revealed aneurysm neck recurrence in 1 patient with saccular aneurysm,no obvious aneurysm recurrence was observed in all other patients. Conclusions Endovascular treatment of intracranial peripheral aneurysms is safe and effective.Choose what specific intervention therapy base on the aneurysm morphology,location, tortuous degree of the parent artery,and the importance of the blood supply area.
