Esophagogastric devascularization with splenectomy has been used for the treatment of upper digestive bleeding due to esophagic varices in hepatoportal mansoni's schistosomic portal hypertension. Nevertheless, early portal thrombosis has hampered this surgical technique (13.3% and 53.2%), compromising the good results on the hemorrhagic side. Supposing that portal circulatory changes, due to the surgical treatment, may play an important role in this kind of complication, our objective was to identify the hemodynamic facilitating factors. Portal hemodynamic aspects, identified by ultra-sonographic Doppler study, from two groups of patients: non-operated upon and splenectomized with esophagogastric devascularization in late post-operatory phase (in excess of 6 moths), with portal hypertension due to mansoni hepatoesplenic portal hypertension and in similar clinical conditions, were compared.
