Abstract/OtherAbstract:
Objectives: Our aim was to describe the hemodynamic patterns and assess the prevalence of reversal of flow (RF) in intrahepatic portal vessels (IPV) in patients with chronic active hepatitis (CAH) and patients with cirrhosis. Patients : 100 consecutive patients with CAH, and 178 consecutive cirrhotic patients (48 Child A, 114 Child B and 38 Child C class) underwent Echo-Color-Doppler for evaluation of flow direction in segmental IPV, right and left portal vein (RPV, LPV), in main portal vein (MPV), splenic vein (SV), superior mesenteric vein (SMV) and porto-systemic shunts (paraumbilical, spleno-renal, left gastric vein). The patients were followed-up clinically for 3-15 months. Results: Patients with CAH showed RF in SV in 1/100 and hepatopetal flow in MPV, SMV, SV, IPV in 99/100 patients. Eleven of 178 (6.2%) cirrhotic patients showed RF only in the SV, 3/178 (1.7%) showed alternating ('back and forth') flow only in IPV, RPV and LPV with continuous hepatopetal flow in PV and 10/178 (5.6%) showed completely RF in IPV. Four of ten patients of this last group showed hepatopetal flow in MPV. The other six patients showed RF in MPV associated with hepatofugal flow through a large left gastric vein in three cases and through the SV in three cases. The other cirrhotic patients (154/178=86.5%) showed hepatopetal flow in IPV, MPV, SMV and SV. In no case RF in SMV was observed. Prevalence of RF in IPV was significantly higher in Child C patients (8/31=25.8%) than Child B patients (5/104=4.7%) and than in Child A patients (0%) (p<0.01). Prevalence of Child C class was significantly higher in patients with RF in IPV (8/13=61.5%) than in patients with RF only in extraepatic portal vessels (2/11=18.2%) and patients without RF (21/154=13.6%) (p<0.001). No patient with RF in IPV was in Child A class. Incidence of death was significantly higher in patients with RF in IPV than in patients without RF and patients with RF only in SV. Conclusions: RF in IPV is not a rare event (9% in our series) that mainly occurs in cirrhosis with advanced liver function impairment. Copyright 1997 Elsevier Science Ireland Ltd.
