Three patients, who received infrarenal aorto-iliac bifurcation grafts, complained of flaccid and insensible feeling on lower extremities immediatedly after surgery. These symptoms were supposed due, in two cases, to spinal cord ischemia or, in remaining one case, to ischemic change of the peripheral nerve, In former cases, spinal cord hypoxia might be caused by interrupted blood supply through spinal artery as it was intercepted temporarily but for about three and a half hours during surgical procedures. In the latter case, cramping of the left iliac artery lasted for five and a half hours, which might result in anoxic damage of the peripheral nerve. Hyperbaric oxygenation (HBO) at two atmospheric absolute (ATA) pressure for 75min and 3 ATA for 90min were repeated everyday for them. In all cases, almost complete sensorimotor recovery was obtained after 15 to 30 instances of HBO, which was combined with physical therapy. HBO seemed to have improved early hypoxic and edematous damages of the spinal cord or peripheral nerve. As an unfavorable complication of abdominal aortic surgery, incidence of sensorimotor disturbance of the extremities is infrequent and/or unpredictable, however, once it occurs, no effective therapeutic maneuvers were developed yet. Through these clinical data, HBO should be introduced more actively for such disorders. One of the key issues to enhance the effect of HBO is that, HBO should be introduced as soon as possible once postoperative nuerologic disorders were diagnosed.

In vascular surgery, thrombo-embolism and hemorrhage are major noisome complications. We report a case of cholesterol emboli which came from atheromatous aortic wall during the thoracoabdominal aortic aneurysm operation. Micro-emboli were migrated into the capillary in the liver, kidney and small bowels, and the patient died of multiple organ failure. The histological examination showed the cholesterol emboli in micro-circulations. The other is a case of <i>in situ</i> thrombus formation in the posterior tibial artery during aortic surgery. The patient with combined (iliac and femoral) lesion had aorto-bifemoral bypass to get better proximal inflow. Just after the operation, we noticed his right lower extremity was pale and cold. Angiography revealed the thrombus distal to the occluded superficial femoral artery. Since the thrombus was too large to pass through any collateral vessels, it should be formed <i>in situ</i>. Femoro-popliteal bypass was added to the primary procedure with success.
