[Late morphologic and hemodynamic changes in the splenic territory of patients with mansoni's hepatosplenic schistosomiasis after distal splenorenal shunt. (Ultrasonography-Doppler study)].

Background: The distal splenorenal anastomosis (Warren's operation) has been indicated for the treatment of high digestive bleeding caused by esophagic varices because it would ideally reduce the venous pressure in the cardiotuberositary territory without changing the mesenteric-portal venous flow. However, the changes it produce in the splenic territory have not been fully understood.

Aim: To appraise the late morphologic and hemodynamic changes in the splenic territory produced by the distal splenorenal anastomosis in patients with portal hypertension due to mansoni's hepatosplenic schistosomiasis complicated by esophagic bleeding.
