Hepatic Swelling and Inferior Vena Cava Constriction

Narrowing of the upper abdominal inferior vena cava in patients with elevated intraabdominal pressure

“…Investigators have speculated that narrowing of the upper abdominal IVC might prompt an increase in circulating renin by obstructing renal vein outflow [6], and reversible renal failure can indeed develop with increased IAP [10]. Our study does not yield information regarding possible physiological consequences of IVC narrowing in our patients.…”

“…The quality of opacification of the intrahepatic and suprahepatic IVC with IV contrast material was evaluated, and deemed satisfactory if these IVC segments were opacified on all relevant images. The liver was also evaluated for abnormalities such as cirrhosis, hepatomegaly, or focal lesions that are known to cause narrowing of the intrahepatic IVC [5,6].…”

Interposition teflon mesenteric caval shunt for bleeding oesophageal varices

“…However, mesenteric caval shunts have not found favour with the majority of surgeons. T h e largest series have been reported by Voorhees and Blakemore (1962) and Gliedman (1965). While the results in each study were satisfactory in the relief of variceal bleeding, there was no clear advantage over the portacaval shunt for the uncomplicated case of chronic liver disease.…”
