title: Correlation between the haemodynamics of portal collateral circulation and the incidence of esophageal bleeding in patients with portal vein thrombosis--a preliminary report.
abstract: The aim of this study was to determine a correlation between the haemodynamics of portal collateral circulation (PCC) and the incidence of bleeding episodes. The prospective analysis included 17 patients with portal hypertension resulting from prehepatic block but without history of oesophageal bleeding. Every two months the changes in PCC and incidence of oesophageal bleeding were evaluated. The follow-up ranged from 3 to 12 months. The statistical correlation between the portal haemodynamic disorders and the tendency to bleed was investigated. Variceal bleeding occurred in 6 patients during the time of observation, mostly in patients with development of hepatofugal PCC. Authors suggest that the development of hepatofugal PCC is the main factor of variceal bleeding in patients with portal vein thrombosis (PVT).
