Stanford Type A Acute Aortic Dissection with Leg Ischemia and Visceral Ischemia
A 52-year-old man developed Stanford type A acute aortic dissection and suffered severe pain in the back and the chest, and numbness of the left lower limb. Contrast-enhanced computed tomography (CT) revealed occlusion of the left iliac artery due to dissection. The celiac artery was also obstructed and the superior mesenteric artery was severely narrowed, but there was no clear sign of organ ischemia. Endovascular treatment in the iliac artery was performed, but the patient complained of right upper abdominal pain 6 hours after the procedure. Serum liver enzyme levels were significantly elevated. Repeat contrast-enhanced CT revealed liver infarction, ischemic cholecystitis, and duodenal ischemia due to decreased collateral flow. We immediately carried out cholecystectomy and revasculariza-tion of the celiac and superior mesenteric arteries using a saphenous vein. The patient underwent central repair for aortic dissection several days after recovery of liver function, and was discharged uneventfully 24 days later.
