Misperfusion of the liver during hepatic artery infusion chemotherapy: value of preoperative angiography and postoperative pump scintigraphy.

Abstract
One purpose of this study was to determine if patients who have anatomic variations in their hepatic arteries are at increased risk for complications associated with the use of intrahepatic arterial infusion pumps. We also tried to determine the value of perfusion studies obtained with 99mTc-microspheres or 99mTc-macroaggregated albumin in detecting postoperative hepatic or visceral misperfusion and in predicting complications in patients with anatomic variants despite pre- or intraoperative attempts to correct the arterial abnormality.
