远端脾肾分流术的血流动力学研究

Helnodynamic study of distal splenorenal shunt(DsRs)

彩超观察门静脉高压血流动力学变化简便易行，有良好临床应用价值。为进一步评价远端脾肾分流术（ＤＳＲＳ）的疗效，作者应用彩色多普勒超声（彩超）观察ＤＳＲＳ手术前后血流动力学变化，将８例ＤＳＲＳ和１４例断流术与对照组比较，结果：ＤＳＲＳ术后３周，门静脉血流（ＰＶＦ）较术前降低５０％。随访２年，部分患者ＰＶＦ继续下降。ＤＳＲＳ与断流比较，ＰＶＦ降低更明显（Ｐ＜０．００１）。结论：ＤＳＲＳ术后早期ＰＶＦ下降，部分病例有持续下降趋势。ＤＳＲＳ选择性分流作用不完全。断流术维持ＰＶＦ作用优于ＤＳＲＳ。

AbstractColor-flow Doppler sonography(FDS)was usedfor assessing the hemodynamic changes in 8 patientsundergoing distal splenorenal shunt(DSRS).Resultswere compared with 14 patients with portalazygos dis-connection (PAD).It was foundthat 3 weeks afterDSRS portal venous flow(PVF)decreased by 50%,and at least in some patients the reduction of the PVFwas a continuous process during the period of twoyears in the DSRS group.The postoperative decreasein PVF in DSRS patients was in sharp contrast to thatin PAD patients (P<0.001),hence PAD is superiorto DSRS in remaining satisfactory PVF。
