Intact Giant Abdominal Aortic Aneurysm Due to Takayasu Arteritis

Abstract

A 35-year-old male fisherman was admitted with complaints of increasing back pain and abdominal discomfort of 1-year duration. Physical examination revealed a prominently visible, expansile, pulsatile, well-defined, nontender abdominal mass in the epigastric, umbilical and both lumbar areas. Computed tomographic (CT) angiography revealed a large juxtarenal aortic aneurysm with a maximum transverse diameter of 14.7 cm with bi-iliac extensions. Anatomy of the aneurysm did not permit endovascular aneurysm repair (EVAR). The patient underwent open surgical inclusion repair using an aorto-bi-iliac, 16 mm x 8 mm, collagen-impregnated, bifurcated Dacron graft. Postoperative recovery was uncomplicated and he left the hospital on postoperative day 5 in good health and has remained so up to the most recent 8-month follow-up. Histopathologic study showed signature features of Takayasu arteritis.
