We describe a 28-year-old man who sustained an open IIIB left ankle fracture dislocation with heel pad avulsion. The patient underwent formal angiography of the left lower extremity, followed by free tissue transfer of a rectus abdominis flap several days later. Intraoperatively, a thrombus was identified in the deep inferior epigastric artery above the femoral artery access site requiring thrombectomy. Histologic analysis estimated the thrombus age at 12 to 72 hours, raising concern that the thrombus was induced during angiogram instrumentation. Donor and recipient site-specific risks of arterial instrumentation (including invasive diagnostics) should be considered when planning free tissue transfer.

Summary:. A healthy 28-year-old woman restrained driver presented to the trauma unit post-MVC with significant vehicular intrusion. Examination demonstrated a 15-cm transverse wound over the medial malleolus and anterior ankle with exposed muscle, tendon, and bone without gross contamination. Her physical examination was otherwise unremarkable. Distal to the wound, there was no Doppler signal in either dorsalis pedis or posterior tibial arteries and the foot appeared cold with delayed cap refill. She was taken to the operating room urgently for debridement and irrigation, open reduction internal fixation of both distal tibia and fibular fractures, and supplemental external fixation application. The foot regained a normal color and capillary refill upon reduction, and biphasic Doppler signals returned.
