Gradual Occlusion of Extrahepatic Portosystemic Shunts in Dogs and Cats Using the Ameroid Constrictor

摘要: Gradual occlusion of the splenic vein, using a specialized device (ameroid constrictor), was evaluated experimentally in three normal beagle dogs. Splenoportograms were used to verify that total vein had occurred all dogs within 4 5 weeks after application device. The ameroid constrictor (AC) also as method gradual vascular 12 and two cats with single, extrahepatic, portosystemic shunts (PSS). Serum bile acid (SBA) concentrations measured portal scintigraphy (PS) performed on 14 animals preoperatively 10, 20, 30, 60 days postoperatively. Two (14%) died from hypertension early postoperative period. One dog one cat developed multiple acquired PSS, confirmed by mesenteric portography 90 operation. Portal primary shunt other 10 animals. Shunt fractions (SF), PS 30 60, declined significantly preoperative values. Significant decreases noted between values for preprandial SBA day postprandial 30. did not correlate SF. Based this study, AC is recommended treatment PSS.
