Arterial reconstruction during pancreatoduodenectomy in patients with celiac axis stenosis--utility of Doppler ultrasonography.
Celiac axis stenosis is found at an incidence of 2%-24% in the general population. During pancreatoduodenectomy in patients with celiac axis stenosis, division of the gastroduodenal artery from the common hepatic artery may cause acute ischemia of the upper abdominal organs, such as the liver, stomach, or spleen. Under these circumstances, the clinical indications of arterial reconstruction remain controversial. Between 1994 and 2003, seven patients with celiac axis stenosis (n = 4) or occlusion (n = 3) underwent pancreatoduodenectomy at our hospital. Arterial reconstruction, including division of the median arcuate ligament, was conducted in two patients; the replaced right hepatic artery was preserved in one patient, and no vascular refinement was undertaken in the remaining four of the seven patients. In two of the four patients without arterial reconstruction or preservation, the serum levels of liver enzymes were markedly elevated (> 800 IU/l) on postoperative day 1, and these patients subsequently developed liver abscesses. Two patients who underwent arterial reconstruction and three patients who showed no decrease in intrahepatic arterial flow under Doppler ultrasonography after clamping of the gastroduodenal artery developed no ischemic complications. Although our experience is limited, when intraoperative Doppler ultrasonography indicates a decrease in the hepatic arterial signals, we believe that reconstruction of the hepatic artery will be necessary to minimize ischemic complications in the liver in patients with celiac axis stenosis.
