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).
SilverHawk斑块旋切术常用于下肢经皮介入治疗。据报道，SilverHawk斑块旋切术过程中轻微穿孔的发生率为0.8%。文献中关于SilverHawk斑块旋切术后极晚期假性动脉瘤形成的报道很少。在此，我们报告1例非常罕见的晚期隐匿性股浅动脉急性破裂病例，患者在接受SilverHawk斑块旋切术1周后出现巨大疼痛性假性动脉瘤形成，并采用Viabahn覆膜支架（美国戈尔公司）进行治疗。
