title: [Splenic venous hemodynamics in portal hypertension].
abstract: The percentage of splenic blood in portal venous flow (SV%) was measured in 96 patients by using scintiphotosplenoportography and angiography. The patients were divided into two groups: Group 1, without collateral pathways from the splenic vein; Group 2, with collateral pathways from the splenic vein. SV% was significantly lower in patients without liver diseases or in patients of Group 1 with liver cirrhosis (LC). SV% was significantly higher in patients with idiopathic portal hypertension (IPH). A significant correlation was observed between SV% and splenic volume or ICGR15. No significant correlation of SV% was found with etiology of LC in patients of Group 1, esophagogastric varices, Child's criteria, portal venous pressure, cholinesterase, hepaplastin test or prothrombin time. Hence, the local hyperdynamic state of the splenic region was detected in patients with CH, LC and IPH.
