Affiliated Hospital, Shandong Medical University, Jinan.

Ultrasonic pulsed Doppler duplex system was used to observe the portal hemodynamic changes before and after shunting or nonshunting operations. The results of preoperative measurements revealed significant increases of blood flow volumes of portal and splenic veins in portal hypertension subjects, and a positive correlation was obtained in the subjects with portal hypertension. Postoperative results showed significant reduction of portal blood flow volume more after shunting than the nonshunting operations. The etiology of portal hypertension and the causes of portal hemodynamic changes due to operations were discussed.

D011170	Portasystemic Shunt, Surgical	Surgical venous shunt between the portal and systemic circulation to effect decompression of the portal circulation. It is performed primarily in the treatment of bleeding esophageal varices resulting from portal hypertension. Types of shunt include portacaval, splenorenal, mesocaval, splenocaval, left gastric-caval (coronary-caval), portarenal, umbilicorenal, and umbilicocaval.
