ABSTRACT

OBJECTIVE
The purpose of this study is to evaluate complications in 70 patients who had underwent endovascular treatment to occlude cerebral aneurysms. METHODS: From May 1999 to December 2002, we treated 70 patients by endovascular treatment or by combination of endovascular treatment and surgery. Complications have been developed in fifteen patients. Twelve patients had anterior circulation aneurysms: 4 posterior commmuncating artery ; 2 anterior communicating artery ; 2 paraclinoid artery ; 2 anterior choroidal artery ; 1 distal internal carotid artery ; 1 middle cerebral artery ; 1 pericallosal artery and three patients had posterior circulation aneurysms: 3 basilar artery tip. RESULTS: The complications related to the coil embolization were the thromboembolic event in 9 cases, rupture of the aneurysm in 3 cases, coil prolapse in 3 cases and coil migration in 1 case. CONCLUSION: The coil embolization can be a alternative good modality in the treatment of cerebral aneurysms. But careful attention should be required to reduce the various complications of procedures and to improve the prognosis of aneurysmal treatment. Effort to overcome the technical problem and to develop more comfortable device are needed for the better results of endovascular treatment.
