Abstract The aim o~ the present work was to study the eect o eradication oesophageal varices by EVS on the portal blood ,flow. Sixteen male patients presented with bleeding esophageal varices comprised the material o~ this study. Their ag~ range. ~rom 30 to 6~ ye.r. with meafl value 42.4 years. Patients were considered ~or the study i~ they had bled from ruptured esophageal varices and had no history of previous endoscopic variceal sclerotherapy. The patients who had bled from esophageal varices after splenectomy were excluded from the study. They weru examined by color duplex Doppler sonography before the begining of EVS and at variceal obliteration. The hepatic blood flow was assessed as regard to amount, direction and presence of pOl-tal vein thrombosis in addition to the presence of portosystemic collaterals. The patients were first resuscitated and exposed to through clinical examination, liver ~unction tests and endoscopic examination o~ upper G.I.T. They were than enrolled in a program of chronic sclerotherapy. We found that the portal blood flow was increased in 15 cases and decreased in one case but the increase was statistically insignificant. and the mean value of this increment was about 26% after EVS. The direction of portal blood flow was hepatopetal both before and after EVS in all cases and this represent a good |
