Endovascular Management of Unruptured Intracranial Aneurysms: Single-Center Report

Abstract

Objective: The exact treatment indications and optimal management strategies of patients with intracranial unruptured aneurysms remain controversial. Material-Method: In this study we present our results and clinical outcomes in a single center of patients with unruptured aneurysms treated with different endovascular techniques. Between April 2008 and October 2014, 106 unruptured aneurysms in 100 consecutive patients were treated with different endovascular techniques in our center. There were 35 male and 65 female patients with a median 53.2 years (range, 15-76 years). Endovascular primary coiling, coiling with balloon remodeling, stent assisted coiling, flow-diversion, intrasaccular flow-diversion or parent artery occlusion were performed according to location, type, complexity and size of the related unruptured aneurysms. Results: At 6 months follow-up, complete occlusion was achieved in 101 aneurysms (100%) and near-complete occlusion in 5 aneurysms (90%-100%). Four patients had procedure-related complications including thromboembolism in 2 patients and aneurysm perforation during the procedure in 2 patients. Follow-up imaging was performed with angiography in 61 patients, with CT angiography in 16 and with MR angiography in 23. Our median surveillance time was 10.05 months (6-50 months). Conclusion: Endovascular treatment of unruptured intracranial aneurysms seems to be a safe method in selected patients according to risk-benefit analysis.
