Endovascular Treatment For Basilar Artery Apex Aneurysms With Guglielmi Detachable Coils

Objective: To explore the safety and efficacy of endovascular treatment of basilar artery apex aneurysms with guglielmi detachable coil. Methods:The data of 14 patients with basilar artery apex aneurysms, who received endovascular treatment with guglielmi detachable coil, were analysed retrospectively. Of the 14 patients, 6 male and 8 female, aged from 17 to 64, 11 patients presented with acute subarachnoid hemorrhage, 3 patients had unruptured aneurysms. The 11 Patients with Acute Subarachnoid Hemorrhage were classified with Hunt and Hess grades at admission. Every patients underwent endovascular embolization of the aneurysm with guglielmi detachable coil. Eight aneurysms with wide necks were treated with newer methods of GDC placement including balloon remodeling GDC embolization technique and stent-supported GDC embolization technique. All patients treated with GDCs were recommended for a 6-month angiographic follow-up examination. Patients with incomplete GDC occlusion of the aneurysm had a 3-month angiographic follow-up examination.Results: All of the 14 aneurysms were embolized with GDCs successfully. One hundred percent occlusion of aneurysms was achieved in 8 patients(57.1%), more than 90% in 4(28.6%) less than 90% in 2(14.3%). Angiographic follow-up (mean 6 months) in 11 patients showed that 3 aneurysms recurred. Thirteen patients were clinically followed up for 18 months and no aneurysm ruptured during the clinical follow-up period. Ischemie events were encountered after the embalization in 1 cases and no patients died.
