Segmental Thrombotic Occlusion of Infrarenal Abdominal Aorta

Abstract

• Five patients had segmental atherosclerotic occlusive disease confined to the midportion of the infrarenal abdominal aorta. Four of five patients had claudication, and in addition, four had evidence of peripheral microembolization and ischemic toes. Local endarterectomy or thrombectomy resulted in satisfactory restoration of distal blood flow in three patients. Two patients required replacement with a prosthetic tube graft. Four of five patients have maintained good pedal pulses and have been asymptomatic for up to 14 years. These five cases were compared and contrasted with other series with similar lesions. Several causal factors are involved in segmental aortic occlusions. (Arch Surg1982;117:1339-1342)
