RESUMO
A rare case of juxtarenal aortic occlusion due to Takayasu's arteritis is reported. A 46-year-old man who had been suffering from intermittent claudication from the age of 44 when Buerger's disease was suspected at another hospital because of exacerbation of the symptom. Occlusion of the abdominal aorta and severe aortic wall thickness were identified by the abdominal CT scan. After the improvement of inflammation, under the diagnosis of juxtarenal aortic occlusion due to inflammatory disease, we performed an aortobifemoral bypass grafting using a Y-shaped prosthesis (proximal anastomosis was end-to-end) found a tight inflammatory adhesion around the abdominal aorta. Histopathological examination of the resected specimen revealed an infiltration of lymphocytes, plasma cells in aortic media and <i>adventitia</i>, severe fibrosis in the aortic <i>adventitia</i>, and a diagnosis of Takayasu's arteritis was made. The postoperative course was uneventful but we should periodically check for inflammatory signs, and anastomotic aneurysms.
