Objective To investigate the outcome of endovascular treatment of large or giant intracranial aneu?rysm by long-term angiographic follow-up. Methods Clinical data of 72 patients with large or giant intracranial aneu?rysms receiving endovascular treatment were analyzed retrospectively. Thirty aneurysms were treated with coil emboliza?tion alone, 14 with stent-assisted coiling, 15 with covered stent-deployment and 13 with parent artery occlusion. Results complete occlusion was achieved in 10 cases of pure coil embolization, 7 cases of stent assisted coil embolization,11 cas?es of completely covered stent-deployment and,13 cases of parent artery occlusion. The postoperative immediate com?plete embolism rate was 56.9%. Nearly completely occlusion was achieved in 17 cases of pure coil embolization, in 6 cas?es of stent auxiliary coil embolization, 4 cases of covered stent-deloyment and zero case of parent artery occlusion. The total postoperative immediate nearly completely embolism rate was 37.5%. Incomplete occlusion was achieved in 3 cases of pure coil thrombosis, 1 case of stent assisted coil, zero case of ,covered stent-deloyment and zero case of parent artery occlusion. The total immediate postoperative incomplete embolization rate was 5.6%. Patients were followed up for 6 to 72 months, with an average follow-up of 24.2 months . All patients had no bleeding. The total periprocedural complica?tion rate was 9.7%and there were no death cases. The recurrence of aneurysm in pure spring coil embolization treatment was higher compared with other treatments. The overall recurrence rate was 23.6%. The recurrent 14 aneurysms were suc?cessfully treated endovascularly. Conclusions Endovascular embolization treatment of intracranial large or giant aneu?rysm is safe and effective but its long-term recurrence rate is high. Thus a close follow-up is needed. Endovascular inter?ventional therapy based on the location of aneurysm and shape characteristics can improve treatment effectiveness and re?duce recurrence rate.
