(A) The dissection flap terminates into the left internal and external iliac arteries. (B) Crossover fem-fem bypass from left to right restorates blood flow to right limb.

A CT angiogram was performed after finally persuading the patient, 20 days after his discharge; it revealed a type A aortic dissection with a dissection flap (entry point) arising from the mid ascending aorta and extending into the left internal and external iliac arteries (Figures 1 and 2).
Computer tomography angiography performed 15 days after emergency reperfusion of the lower limb revealing: (A) A dissection flap in the ascending aorta which extends down to the descending thoracic aorta. (B) The dissection flap continues for a short distance into the left common carotid and left subclavian arteries without causing any symptoms. The brachiocephalic artery is not involved. (C) Within the abdominal aorta, the dissection flap extends into the celiac axis.

Follow-up imaging studies with CT and/or MR angiogram performed regularly shows a stable dissection and the patient remains symptom free (Figure 3).
