摘要
作者就经颈静脉肝内门体静脉分流术（ＴＩＰＳ）前后门静脉系统血液动力学的变化进行了分析，ＴＩＰＳ组１１例分别于ＴＩＰＳ前后测定了门静脉、脾静脉、肝动脉的血管直径、血流量及压力变化，并设立了对照组（１０例）进行对比分析。对照组测定结果为：门静脉血流量（ＰＶＦ）：９４７．２ｍｌ／ｍｉｎ±１３３．４ｍｌ／ｍｉｎ；脾静脉血流量（ＳＰＶＦ）：２３９．６ｍｌ／ｍｉｎ±１１６．３ｍｌ／ｍｉｎ；肝动脉血流量（ＨＡＶ）：２４１．６ｍｌ／ｍｉｎ±７８．８ｍｌ／ｍｉｎ。ＴＩＰＳ组术前、术后测定结果为：ＰＶＦ：８８３．２ｍｌ／ｍｉｎ±２３３．４ｍｌ／ｍｉｎ，９５８．７ｍｌ／ｍｉｎ±１８５．２ｍｌ／ｍｉｎ；ＳＰＶＦ：４４８．９ｍｌ／ｍｉｎ±１１１。６ｍｌ／ｍｉｎ；３３３．１ｍｌ／ｍｉｎ±１０１．５ｍｌ／ｍｉｎ；ＨＡＶ：２２５．３ｍｌ／ｍｉｎ±１２２．７ｍｌ／ｍｉｎ，２４９．３ｍｌ／ｍｉｎ±１０３．８ｍｌ／ｍｉｎ。ＴＩＰＳ组术前、术后测定门静脉压力结果为：３．９４ｋＰａ±０．４６ｋＰａ，２．５２ｋＰａ±０．６ｋＰａ。结论：ＴＩＰＳ术后门静脉系统血流发生改变：（１）门静脉压力下降。（２）门静脉主干血流增多，肝组织灌流轻度减少。（３）脾静脉?
Abstract In this study portal venous flow(PVF),splenicvenous flow(SPVF),hepatic artery volume(HAV),and portal pressure were measured before arid afterTIPS in 11 patients with portal hypertension. The re-sults were compared with those of normal controls. Inthe normal controls PVF averaged 947.2±133.4ml/min, SPVF239.6±116.3ml/min, and HAV 241.6±78.8ml/ min. In the TIPS group before and afterTIPS,PVF was 883.2±233.4ml/min vs.958.7±185.2ml/min;SPVF was 448.9±111.6ml/min vs.333.1±101.5ml / min;HVP was 225.3±122.7ml/minvs. 249.3±103.8ml/min.Portal pressure droppedfrom3. 94kPa±0.46 to 2.52 ± 0.60kPa after TIPS.We conclude that in patients after TIPS portal pressuredrops blood flow in the truck of the portal vein increas-es, flow of hepatic tissue decredses,and blood flow insplenic vein decreases. Blood flow in hepatic aftery wasnot significantly changed.
