Clinical Study on Change of Hemodynamics in the Portal Venous System after Spleno-renal Shunt and Pericardial Devascularization.

To study the clinical and hemodynamic changes of the portal venous system after spleno renal shunt plus pericardial devascularization(SRS+PCDV). Methods: In 99 patients with portal hypertension(PH), the hemodynamic parameters of the changes of the portal venous system were studied by Doppler color flow imaging(DCFI) before, during and after operation. Results: SRS+PCDV group: The PVF and FPP respectively decreased by 36.1%±7.8% and 33.99%±9.53% postoperatively comparing with preoperation(P0.05), which still corresponded to the normal upper limit, suggesting that the liver kept a good perfusion from the portal vein. The postoperative pressure of PVF and FPP in SRS+PCDV group were higher than that of SRS group(P0.05), but lower than that of PCDV group(P0.05). Conclusions: ①After PCDV, the hepatic perfusion from the portal vein was still kept within normal limits. ②The congestive state of the portal vein was released after SRS, hepatic perfusion from the portal vein was thus decreased significantly. ③SRS+PCDV could decrease moderately the PVF and FPP, and helped to stop the bleeding. The hepatic perfusion was in a good state after SRS+PCDV, while the congestive state of the portal venous system was released as well.
