门静脉高压症脾厚度与门静脉血流动力学间的关系

The relationship between thickness ofspleen and portal hemodynamics in portal hy-pertension

通过门静脉高压症的脾脏厚度与门静脉系统血流动力学指标间的相关性分析发现：脾脏厚度与门静脉主干内径、脾静脉内径、脾静脉血流量及切脾后自由门静脉压（ＦＰＰ）呈正相关，与门静脉主干的血流时间平均速度呈负相关，差异有显著性意义（Ｐ＜０．０５）或有非常显著性意义（Ｐ＜０．０１）。说明脾脏越大门静脉系统的高阻力、高动力血流状态越严重。切脾后ＦＰＰ值较切脾前ＦＰＰ值显著降低（Ｐ＜０．０１）。离断术后ＦＰＰ值又升高，但未达切脾前ＦＰＰ值水平，脾肾静脉分流术后ＦＰＰ值与切脾后ＦＰＰ值相比几乎无改变。说明脾切除是降低ＦＰＰ的主要因素，选择含有脾切除的手术方式是治疗门静脉高压症较合理的手术方法。

The relation analysis between splenic thickness and portal hemodynamics showed that there was a posotive relationship betweensplenic thickness and MPVD. SVD. SVF. FPPafter splenectomy. But there was a negative relationship between splenic thickness and MPV-TAV. The differences were significantP<0.05)or highly significant (P<0.01).These results showed that the bigger the splenic volume. the more serious the hyperdy-namies and that high resistance state of bloodflow of the portal system. The value of FPPdropped markably after splenectomy, but there was an increase in FPP value after devascular-ization. However, the FPP value after devascu-larization was lower than before the splenecto-my,The FPP value after splenectomy did notshow any significant change when splenic-re-nal vein shunt operation was performed Ourresults suggest that splenectomy is the mainfactor for decrease of the FPP.Therefore,sur-gical interventions including splenectomy forthe treatment of portal hypertension are justi- fiable.
