Stenosis of which of the following vessels is associated with the highest patency rates following angioplasty or stenting?: (A) Medial circumflex artery, (B) Iliac artery, (C) Superficial femoral artery, (D) Popliteal artery
Answer is B. Angioplasty and stenting of the iliac vessels has a patency rate of 75% at 5 years; PTA and stenting of all other vessels has a much lower patency than bypass procedures. The FDA has only approved illiac artery stenting.
