ABSTRACT
We report the case of a 69-year-old male patient who was admitted to our department with an acute type A dissection complicated by ischemia of the left lower limb. During surgery for acute type A dissection, the patient underwent concomitant femoro-femoral crossover bypass graft placement to ensure blood supply of the left lower limb during surgery and minimize ischemia-reperfusion injury. The patient underwent supracoronary replacement of the ascending aorta while in deep circulatory arrest with a deepest core temperature of 25°C. Postoperative computed tomography showed antegrade perfusion and patency of the crossover bypass. Postoperative course was eventless without sequelae, especially of the left lower limb. We conclude that concomitant crossover bypass graft reduces the risk of ischemia-reperfusion injury in lower limb ischemia in patients undergoing surgery for acute type A dissection.
