Early experience using the Wallgraft in the management of distal microembolism from common iliac artery patholology.

Blue toe syndrome commonly occurs as a result of aneurysmal or atherosclerotic disease in the iliac arteries. Surgery, angioplasty, or intraarterial stent placement are the most common treatment options but the optimal management has not been defined. Here we report managing distal microembolization from iliac artery atherosclerosis associated with aneurysmal dilation with the Wallgraft Endoprosthesis, a self-expanding metallic stent covered with Dacron.

Hemodialysis access assessment with intravascular ultrasound.

Reliable identification and treatment of specific hemodialysis access complications may improve access patency and result in significant cost reduction. Angiography is the gold standard for the evaluation of vascular access; however, it has significant limitations. Intravascular ultrasound (IVUS) is a relatively new technique capable of detecting subtle vascular abnormalities.
