Percutaneous treatment of delayed post-atherectomy superficial femoral artery pseudoaneurysm.

SilverHawk atherectomy is commonly used in lower extremity percutaneous interventions. Minor perforations during SilverHawk atherectomy procedures are reported at a range of 0.8%. There are few reported cases in the literature about very late pseuodoaneursym formation after SilverHawk atherectomy. Herein we report a very unusual, late, concealed, acute rupture of superficial femoral artery with a large, painful pseuodoaneursym formation, 1 week after Silver- Hawk atherectomy and its treatment with Viabahn stent graft (W.L. Gore & Associates).
