Covered stent placement for neurovascular disease.

Abstract

We describe an endovascular technique in which covered stents were used to occlude a parent vessel. In one patient, with a giant paraclinoid aneurysm, a Gortex-covered Palmaz stent was used to occlude the cervical internal carotid artery and to create thrombosis in the aneurysm. In the second patient, with a high-flow vertebrojugular fistula, a hooded stent provided definitive treatment after an attempt to close the fistula by detachable balloon therapy failed. Follow-up of these patients revealed stable stent position and no untoward effects of permanent vessel occlusion.
