Hepatic arterial perfusion scintigraphy with Tc-99m-MAA: use of a totally implanted drug delivery system

Journal Article · · Radiology; (United States)

Tc-99m-MAA hepatic arterial perfusion scintigraphy (HAPS) using a totally implanted drug delivery system was employed for hepatic arterial chemotherapy in 147 patients (335 studies). Complete perfusion of the involved liver was seen in 88% of patients initially and remained good on follow-up. A significant decrease in hepatic and/or extrahepatic perfusion associated with a hot spot at the tip of the catheter indicated hepatic arterial thrombosis. Extrahepatic perfusion was seen in 14% of cases, usually in the distribution of the stomach, small bowel, and spleen. Significant symptoms of drug toxicity were seen in 70% of patients with extrahepatic perfusion, compared to 19% of those without it.
