[Ischemia of the lower limbs as a symptom of acute dissection of the ascending aorta].

A 27-year-old man, two 54-year old men and a 64-year-old woman presented with aspecific symptoms: acute pain and tingling in the shoulders plus paraplegia; exertional dyspnoea and tingling in both feet for the past week; increasing shortness of breath and cold, pale legs and feet for the past week; acute retrosternal pain, incontinence and paraparesis. The cause was dissection of the ascending aorta (type A). Following the operation, the legs were amputated because of ischaemia. The 27-year-old man and one of the 54-year-old men died; the other two patients made a satisfactory recovery. Acute type-A aortic dissection is a life-threatening disease that must be recognised early because it is an absolute indication for emergency surgery. The initial manifestation of type-A dissection may be very aspecific. Post-operative lower limb ischaemia, as the first symptom of this disease, is rare and usually disappears after surgery for type-A dissection. In some cases, however, ischaemia persists and alters the post-operative course dramatically.
