Percutaneous pancreatography: case report and presentation of technique.

A case of traumatic pancreatitis with a radiopaque calculus producing pain by obstructing the distal pancreatic duct is presented. Preoperative ductal anatomy was defined by a percutaneous pancreatogram that established the presence of mechanical duct obstruction as the cause of pain, and the potential for operative relief of duct obstruction. A remission from pain resulted from pancreatic duct decompression by a lateral pancreaticojejunostomy.

Hepatic artery flow improvement after portacaval shunt: a single hemodynamic clinical correlate.

We have documented a highly significant increment in hepatic arterial flow following a portacaval shunt in patients with cirrhosis of the liver and portal hypertension. In contrast with other hemodynamic variables, the increment in arterial flow was directly related to morbidity, hospital mortality, and long term survival. Patients with increments smaller than 100 ml/min had the worst clinical results.

Spontaneous reversal of portal blood flow: the case for and against its occurrence in patients with cirrhosis of the liver.

Because of its presumed serious clinical significance, we made an analysis of the evidence for and against the occurrence of spontaneous reversal of portal flow in cirrhosis of the liver. We examined the evidence obtained from manometric studies, radioactive tracer studies, radiologic studies, and actual measurements of magnitude and direction of portal blood flow. Concerning manometric studies, we introduced a physical analysis, based on first principles, which demonstrates that the occluded portal pressures cannot be used to construct a hydraulic gradient for portal flow.

The hemodynamics of portal hypertension revisited: determinants and significance of occluded portal pressures.

We bring up to date our series of direct measurements of portal flow and pressure in patients with cirrhosis of the liver. In 153 patients the portal flow averaged 447 plus or minus 350 ml. Hg per minute and the portal pressure 28.
