Treatment of a ruptured dissecting vertebral artery aneurysm with double stent placement: case report.
A ruptured dissecting right vertebral artery aneurysm was treated by means of double stent placement with two overlapping stents. Control angiography performed 3 d after stent placement revealed beginning aneurysmal thrombosis. Substantial reduction in aneurysmal size was observed after 4 wk, whereas total occlusion was observed after 3 mo. The reduced stent porosity caused by the overlapping stents, which result in significant hemodynamic changes inside the aneurysmal sac, may accelerate intraaneurysmal thrombosis and may be helpful in achieving a more rapid complete occlusion compared with that achieved by single stent placement.
