Abstract

Lower extremity ischemia following deployment of a vascular closure device for access site closure after a transfemoral endovascular procedure rarely occurs. A 68-year-old woman diagnosed with subarachnoid hemorrhage due to a ruptured anterior communicating aneurysm was treated by endovascular coil embolization. The StarClose SE device was deployed for right femoral arteriotomy closure. After 2 days, critical ischemia occurred on her right lower leg due to total occlusion of the popliteo-tibial artery. Emergent surgical embolectomy was performed and the nitinol clip of the StarClose device was captured in the lumen of the tibioperoneal trunk. Although StarClose is an extravascular closure system, intravascular deployment, distal migration, and resultant critical limb ischemia can occur.
