MeritCare Hospital First in Region to Implant New Stent
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."
