[Acute Leg Ischemia at Acute Aortic Dissection].

Legs ischemia might be associated with acute aortic dissection, in acute phase or even in subacute phase. In general, immediate central repair for acute aortic dissection is mandatory prior to intervention of leg ischemia because central repair might improve leg ischemia. Depending on condition of leg ischemia, revascularization of occluded artery should be considered. The perfusion to ischemic leg during central repair is useful to diminish leg injury. There are some useful modalities for revascularization such as some route of extra-anatomical bypass, placing of stent graft for closing entry site of dissected aortic wall. Multiple organs injury are occurred simultaneously by occlusion of organ branches on aortic dissection. Leg ischemia is associated frequently with other organs ischemia, and could be a pilot sign for abdominal organ ischemia.
