MeritCare Hospital First in Region to Implant New Stent

MeritCare is first in the region to offer a newly approved device for treating Peripheral Vascular Disease (PVD). The Gore Viabahn Endoprosthesis with Heparin Bioactive Surface is a stent-graft for vascular bypass usually in the main artery of the thigh. One of the first procedures utilizing this new technology was performed on Tuesday, Oct. 16, at MeritCare by interventional radiologist Dr. Corey Teigen.

PVD is a narrowing of blood vessels that restricts blood flow, caused by the formation of fatty plaques inside the blood vessel wall. To keep the blocked area open, an interventional radiologist inserts a stent-graft into the patient's main artery of the thigh during a minimally invasive procedure using a catheter.

The Gore Viabahn Endoprosthesis with Heparin Bioactive Surface stent is different from other stent-grafts because of its heparin coating, which prevents blood clots from forming.

"Sometimes arteries will reclot after a stent is placed," said Dr. Teigen. "This may require the patient to have bypass surgery. The heparin-coated stent prevents this from happening."
