Abstract
Objective
To evaluate the safety and effectiveness of one-stage intravascular interventional treatment for intracranial multiple aneurysms.
Methods
From January 1, 2010 to January 1, 2018, the data of patients with multiple intracranial aneurysm undergoing one-stage endovascular embolization in the Department of Nerurosurgery, Puning People's Hospital, Guangdong Province were analyzed retrospectively. The clinical and angiographic findings at discharge and follow-up were evaluated.
Results
A total of 16 patients with multiple intracranial aneurysms received one-stage endovascular treatment were enrolled. Among them, 10 were females and 6 were males; their age was 49.5±17.2 years; 5 patients were subarachnoid hemorrhage caused by rupture of intracranial aneurysms, three of them were classified as grade Ⅰ and two were classified as grade Ⅱ by the World Federation of Neurosurgical Societies (WFNS). There are a total of 35 aneurysms, 13 patients had 2 intracranial aneurysms, and 3 had 3 intracranial aneurysms. There were 3 posterior circulation aneurysms and 32 anterior circulation aneurysms; the mean diameter of the aneurysms was 6.9±3.3 mm. Fifteen aneurysms were only treated with coil embolization, and 20 aneurysms were treated with stent-assisted coil embolization. No treatment-related complications occurred. Thirteen patients were followed up for a total of 17.7±6.4 months (range, 6-28 months). The modified Rankin Scale score of 12 patients was 0 and 1 was 6 (died of rebleeding). The imaging follow-up data of 23 aneurysms in 10 patients were obtained. They were followed up for 10.2±3.3 months (range, 6-15 months), 20 aneurysms did not recur and 3 (3/23, 13.0%) recurred.
Conclusions
One-stage endovascular embolization is a safe and effective treatment for multiple intracranial aneurysms, and its long-term outcome should be further evaluated.
