Abstract
Objective: To report the long-term results of non-hemorrhagic vertebral artery dissecting aneurysms (nhVADAs) treated by stenting alone.
Methods: Between January 2001 and December 2002, single or dual stents were placed in 2 of 5 patients with nhVADA who gave their informed consent. The patients were followed by 3-dimensional computed tomography (3D-CT), cerebral angiography, and intravascular ultrasonography.
Results: No ischemic or hemorrhagic complications were observed. At the 10-year follow-up, total or subtotal occlusion of the aneurysmal sac was achieved, and ectopic calcification was found in the thrombosed aneurysmal sac.
Discussion: In these cases, the use of balloon-mounted coronary stents led to straightening of the parent artery as well as alteration of the in-flow, which can contribute to flow stagnation and subsequent thrombosis of the aneurysms.
Conclusion: The use of stenting alone may afford a favorable long-term outcome for nhVADAs and could be a durable therapeutic choice.
