Objective：In spite of advance of endovascular treatment for intracranial aneurysms, the stability or durability of embolized intracranial aneurysms is unknown. The aim of this study is to assess clinical and angiographic results of aneurysms treated with coils and the rate of compaction and re-treatment.
Methods：Between July 2001 and December 2005, 135 intracranial aneurysms of 123 patients were treated with endovascular methods at our hospital. Ninety eight of 135 intracranial aneurysms were ruptured aneurysms and 37 were unruptured aneurysms. The immediate postoperative angiographies, follow-up angiographies, medical record and operation records were reviewed retrospectively.
Results：Of the 123 patients, 78 were female and 45 were male. The feasibility of coil embolizations was 95.7% (135/141). Ninety (73.2%) experienced excellent or good outcomes (GOS 5 or 4), 14 (11.4%) had fair or poor outcomes (GOS 2 to 3), and 19 (15.4%) died (GOS 1). Immediate postoperative angiographies in 135 aneurysms revealed total occlusion in 111 cases (82.2%), neck filling in 20 cases (14.8%), and incomplete in 4 cases (3.0%). Follow-up angiographies (1 month~49 months) were performed 84 cases (62%). In last follow-up angiographies, there were total occlusion in 52 cases (61.9%), neck remnants in 26 cases (31.0%), and incomplete occlusion in 6 cases (7.1%). There was only one case of postoperative rebleeding. Although angiographic changes were seen in 24 cases (17.8%), only 9 cases were re-treated with coil embolization (6.6%).
Conclusion：In our study, 90 patients (73.2%) revealed good clinical result with coil embolization. Angiographic changes were revealed in 17.8%, 6.6% of all treated aneurysms had required re-treatment.
