Abstract:
It is presumed that visceral ischemia is caused as a result of fighting between the lower limb and intraperitoneal organs to steal blood in aortoiliac occlusive disease (AIOD). Accordingly, an investigation has been made of this “aortoiliac steal” phenomenon. Out of 65 AIOD patients, the case in whom the main collateral circulation to the lower limb was found to originate in the intraperitoneal visceral arteries by angiography were only 2 (3%), both of which showed, however, no visceral ischemic symptom. Intraoperative changes in pelvic visceral hemodynamics were observed in 19 cases undergone either aorto-bifemoral or axillo-bifemoral bypass operation (AFB) using Doppler's ultrasonic trans-anal method. As a result, visceral circulation was maintained favorably even after AFB, further suggesting the possibility that not only the circulation of the inferior limb but the visceral circulation is improved directly by AFB. Visceral ischemia is considered to occur in the patient in whom concomitant stenotic lesion is present in the celiac artery or superior mesenteric artery, for which full attention should be paid to visceral circulation also in the patients with ischemia in the lower limb.
