Preoperative visceral angiography alters intraoperative strategy during the whipple procedure

Abstract

To determine the importance of preoperative visceral angiography prior to pancreaticoduodenectomy, all Whipple procedures performed between 1985 and 1991 at the Virginia Mason Medical Center were retrospectively reviewed. During this period, 77 pancreaticoduodenectomies were performed for both neoplastic disease (n = 54, 70%) and chronic pancreatitis (n = 23, 30%). Sixty-four preoperative angiograms were obtained, of which 39 (61%) were abnormal findings. Thirty percent (19 of 64) of the angiograms revealed a significant vascular abnormality that required specific preoperative or intraoperative measures that might not have been performed without knowledge of these findings. Examples include celiac axis revascularization for celiac occlusion, hepatic artery preservation for replaced vessels, preoperative embolization for pseudoaneurysm or arteriovenous fistula, and splenectomy for splenic vein thrombosis. Because of the high percentage of significant findings requiring an intraoperative or preoperative technical change, we recommend the use of angiography in order to diminish morbidity in all patients preparing to undergo pancreaticoduodenectomy.
