title: Surgical treatment of juxtarenal aortic occlusion.
abstract: From 1974 to 1976, four patients with juxtarenal aortic occlusion were operated upon with no surgical mortality. Thromboendarterectomy (TEA) of the aorta with renal revascularization was performed in one patient, and TEA with grafting in three. Intraoperative renal protection was particularly important, since suprarenal aortic clamping was often required in these cases. Possible renal embolism developed in one patient postoperatively. In order to prevent renal embolism and to minimize ischemic insult to the kidney, the value of the following procedures was stressed; (a) irrigation of aortic lumen with saline after TEA under suprarenal aortic clamping with renal arteries kept occluded, and (b) re-application of aortic clamp below the renal arteries after irrigation. Since the most distal level of occlusive process was the common femoral artery in our series, the patient with this disease entity should be treated more actively.
