[Short-term and long-term effectiveness of endovascular embolization in treating intracranial aneurysms]
1Department of neurosurgery, Pearl River Hospital, The First Medical University of PLA, Guangzhou 510282, China.
Objective:
To study the short-term and long-term effectiveness of endovascular embolization with Guglielmi detachable coil (GDC) or mechanical detachable spiral (MDS) intreating intracranial aneurysms.
Methods:
362 patients with cerebral aneurysms were treated by endovascular embolization with GDC or MDS. Follow-up interviews in the form of correspondence or hospital visit were conducted to 173 of those patients 3 approximately 24 months after the treatment. DSA cerebral artery angiography was made to 84 patients.
Results:
The clinical symptoms disappeared gradually after the treatment among all of the interviews. No subarchnoid hemorrhage was found. All of the 56 cases with ocular paralysis recovered, 1 case in a week, 52 in a year, and 3 in 18 months. Visual acuity improved to different degrees among 10 cases with visual disturbance in 6 months. Five of the 84 patients who received DSA angiography showed recurrence of aneurysm. Then cause of recurrence was absorption of MDS coils in 2 cases and shifting of the coil in 3 case.
Conclusions:
Endovascular embolization is an effective method in treating the intracranial aneurysms with minimal invasiveness and few complications.
