Abdominal aortic aneurysm in situs inversus totalis.

Situs inversus totalis refers to a mirror-image reversal of the normal position of the internal organs. The recognition of concomitant anomalies, such as in the cardiac, venous, gastrointestinal, and urinary systems, is extremely important because these anomalies may disturb the surgical procedure for the concurrent disease in situs inversus totalis. The authors describe a case of successfully repaired abdominal aortic aneurysm with a false aneurysm of the right external iliac artery in situs inversus totalis. The coexistence of abdominal aortic aneurysm has been seldom encountered. The presence of anatomical anomalies significantly increases operative risk. The surgical management of patients with abdominal aortic aneurysm in situs inversus totalis is discussed.
