Abstract
We report two cases of Stanford type B aortic dissection with occlusion of the infrarenal abdominal aorta. Case 1) A 69-year-old woman complained of back pain and was referred to our hospital. Computed tomography (CT) showed Stanford type B aortic dissection and conservative therapy was started. During the course of her treatment, pain in both lower extremities appeared at rest and CT showed occlusion of the infrarenal abdominal aorta. Right axillo-bifemoral bypass was performed and her postoperative course was uneventful. Case 2) An 82-year-old man complained of sudden back pain, lumbago and paralysis of both lower extremities and was transported to our hospital by ambulance. CT showed Stanford type B aortic dissection and occlusion of the infrarenal abdominal aorta. Emergency right axillobifemoral bypass was performed, but he died 3 days after the operation because of myonephropathic metabolic syndrome (MNMS). Axillo-bifemoral bypass is a useful therapy for occlusion of the abdominal aorta, but special attention is needed for the acute onset of MNMS after the operation.
