Controlled Limb Reperfusion in a Case of Acute Abdominal Aortic Occlusion Underwent Thrombectomy and Stent Graft

Abstract

Acute limb ischemia not only leads to lower extremity amputation, but also has a high mortality rate. It is due to ischemia-reperfusion injury which can affect the entire body. We experienced a case of acute abdominal aortic occlusion with ischemia in both lower extremities triggered by infection. A 64-year-old man suddenly developed acute abdominal aortic occlusion during receiving antibiotic treatment for Lemierre syndrome. Thrombectomy was performed and stent graft was used to ensure vascular lumen. In addition, we performed controlled limb reperfusion to avoid ischemia-reperfusion injury. After the operation, he developed compartment syndrome and acute kidney injury, but recovered immediately. Controlled limb reperfusion is effective technique to avoid ischemia-reperfusion injury such as hyperkalemia, lethal arrhythmia or metabolic acidosis, and can improve outcome.
