The use of stents in the treatment of traumatic intimal flaps: case report.

Treatment of arterial traumatic intimal lesions is controversial due to its unknown natural history. Current therapeutical options include arterial reconstruction and clinical observation. The idea of using stents to correct intimal flaps is based on their use to correct dissections, flaps, and arterial irregularities after angioplasty. We report the successful treatment of a traumatic intimal flap of the superficial femoral artery, caused by gunshot trauma, with a Palmaz stent in the acute period. One year after the operation, a duplex scan revealed normal flow in the artery and complete exclusion of the intimal flap; distal pulses were palpable, and the patient was completely asymptomatic.

Endovascular grafting of a popliteal aneurysm using the saphenous vein.

PURPOSE: To report the successful endovascular exclusion of a popliteal aneurysm using a saphenous vein stent-graft. METHODS AND RESULTS: A 1.9-cm popliteal aneurysm in a 75-year-old man was excluded by an endovascular stent-graft constructed from a segment of a greater saphenous vein to which a Palmaz stent was attached at its proximal end. The operation was performed through an open posterior approach to the distal popliteal artery. The stent-graft was introduced in retrograde fashion and passed up to the superficial femoral artery, where the proximal stent was deployed. Distally, a conventional anastomosis was performed with standard suture technique. Follow-up at 2 months shows continued exclusion of the aneurysm and patency of the bypass. CONCLUSIONS: Saphenous stent-grafting is a promising technique in the less invasive treatment of popliteal aneurysms. Further experience and longer follow-up are required before this technique can replace open surgery in clinical practice.
