Abstract:
We report two cases of patients with ruptured vertebral artery dissecting aneurysms that were treated using double overlapping stent placement. Angiography performed immediately after the procedure revealed a significant reduction of aneurysmal filling due to the intraaneurysmal thorombosis. In one case, complete disappearance of the lesion was observed after seven days and in the another one, the size of previous aneurysm sac was decreased on 7th post-procedure day. The reduced stent porosity caused by the overlapping stents, which result in significant hemodynamic changes inside aneurysmal sac, may accelerate intraanuerysmal thromobosis and may be helpful in achieving a more rapid complete occlusion of aneurysm. This double stent method may represent a therapeutic alternatives for dissecting vertebral artery aneurysm in which conventional endovascular techniques or stent supported coil embolization is not considered feasible and surgical treatment is contraindicated.
