Abstract:
In order to evaluate portal venous hemodynamics before and after TIPS, transrectal portal scintigraphy was performed in 8 patients. In all 8 patients, scintigram before TIPS demonstrated hepatofugal flow in the portal vein and less accumulation of radioisotope in the liver. In the scintigrams for follow-up of TIPS, the flow direction in the portal vein changed to be hepatopedal. In 3 of the patients in whom stent shunt was occluded after TIPS, the portal blood flow was turned to be hepatofugal again. It is concluded that transrectal portal scintigraphic studies of the TIPS patients provide noninvasive evaluation of portal hemodynamics.
