Major hepatic resection and portal pressure.
Although other reports have stressed the inevitability of portal hypertension and splanchnic pooling following major liver resections, clinical observations during 30 major hepatic resections and measurements of portal pressure in three consecutive trisegmentectomies fail to support this contention. If the remaining liver is normal and careful anatomic dissection is used, major resections can b...
متن کاملPrediction of portal pressure from intraoperative ultrasonography.
BACKGROUND Portal hypertension is a major risk factor for hepatic failure or bleeding in patients who have undergone hepatectomy, but it cannot be measured indirectly. We attempted to evaluate the intraoperative ultrasonography parameters that correlate with portal pressure (PP) in patients undergoing hepatectomy. METHODS We examined 30 patients in whom PP was directly measured during surgery...
متن کاملPortal hypertensive colopathy: endoscopic findings and the relation to portal pressure.
Portal hypertensive colopathy (PHC) is a new clinical entity in patients with liver cirrhosis. In this study, colonoscopic findings and clinical features including upper gastrointestinal endoscopy and hepatic hemodynamics were prospectively investigated among 35 PH patients with a hepatic venous pressure gradient (HVPG) of greater than 12 mmHg due to chronic liver diseases. Colonoscopy was also...
متن کاملRelationship of splanchnic blood flow and portal venous resistance to elevated portal pressure in the dog.
To determine the relationship of splanchnic blood flow and portal venous resistance to elevated portal pressure, in situ perfusion of the splanchnic circuit was carried out in 12 freshly killed dogs at varying perfusion rates and degrees of acute and chronic portal vein constriction. In six normal dogs before being killed, portal pressure averaged 8-8 +/- 1-2 mmHg and portal flow 658 +/- 81 ml/...
متن کاملEffects of endothelin and vasopressin on portal pressure of rats.
Endothelin is a vasoconstrictor peptide which has recently been isolated and sequenced from the vascular endothelial cells. It was reported to increase blood pressure in vivo and produce a prolonged contraction with a slow onset in vitro. The purpose of this study was to investigate whether endothelin can lower the portal pressure as another endogenous vasoconstriction peptidevasopressin (AVP) ...
