    Abstract:
    The purpose of this study was to examine the hemodynamic changes of the spleen and the subsequent influence on the numbers of blood cells both during and 1 month after distal splenorenal shunt (DSRS) with splenopancreatic disconnection in 20 patients with portal hypertension. The intraoperative splenic blood flow, measured with an electromagnetic flowmeter, significantly increased after shunt insertion: the mean percentage increases within the splenic vein and artery were 60% (p less than 0.01) and 37% (p less than 0.05), respectively. The splenic venous blood flow, measured with a pulsed Doppler flowmeter, had not changed significantly 1 month postoperatively (676 +/- 501 to 540 +/- 306 ml/min). The WBC and platelet counts significantly (p less than 0.05 and p less than 0.01, respectively) increased 1 month postoperatively, whereas there was a small, but significant (p less than 0.05), decrease in RBC count. We concluded that splenic blood flow increases immediately after DSRS with splenopancreatic disconnection, but this increase may be only short term. The influence of the postoperative hemodynamic changes on blood cell count is uncertain.
