Transmetatarsal amputation in the setting of antiphospholipid antibody syndrome

Antiphospholipid syndrome is a hypercoagulable disease that can present foot and ankle surgeons with a unique challenge in treating patients who present with thrombosis and ischemia despite having normal pedal pulses. Appropriate perioperative management is imperative in these patients, because limb- and life-threatening complications can occur postoperatively, despite aggressive anticoagulation. We present the case of a 46-year-old male who underwent a transmetatarsal amputation and, despite aggressive therapy, developed a myriad of complications postoperatively. At 10 months postoperatively, the patient was doing well in an accommodative orthotic with minimal pain while receiving continued aggressive therapy and follow-up examinations by a number of specialists to treat his antiphospholipid syndrome.
