门脉高压的诊断肝静脉楔入压与B超的相关性研究

Diagnosis of the Portal Hypertension: Study of the Correlation Between

目的：对门脉高压患者进行肝静脉楔入压（ＷＨＶＰ）测定及Ｂ超检查，对比分析以探讨两种影像检查方法的相互关系及其诊断价值。材料与方法：对２２例临床确诊的肝硬化门脉高压患者行ＷＨＶＰ测定，测量ＷＨＶＰ及肝静脉压力梯度（ＨＶＰＧ）。该检查前两天内行腹部Ｂ超检查测量门脉及脾静脉内径、脾两极径等指标。结果：本组患者ＷＨＶＰ４．２８±１．２０８ｋＰａ及ＨＶＰＧ３．３６５±１．２１７ｋＰａ均呈明显升高。Ｂ超检查示平均门脉主干内径１．５３ｃｍ，平均脾静脉内径１．０１ｃｍ，平均脾两极径１４．５２ｃｍ。ｔ检验两组指标呈正相关。结论：两种方法所得结果的相关性良好，对门脉高压的诊断，ＷＨＶＰ的敏感性为１００％，Ｂ超达９０％以上。

Objective: The aim of this study was to compared the diagnostic value and correlation of the wedged hepatic venous pressure (WHVP) and the findings by B mode ultrasound.Materials and Methods: WHVP and hepatic venous pressure gradient (HVPG) were measured in 22 patients with the cirrhotic portal hypertension. We had measured the portal and spleenic vein diameter and spleenic bipolar diameter (PVD, SVD, SBD) by B mode ultrasound in 2 days before WHVP measuring.Results: In those patients, WHVP (4.289±1.208kPa), HVPG (3.365±1.217kPa), PVD (mean 1.53cm), SVD (mean 1.01cm) and SBD (mean 14.52cm) had significantly increased. The positive relation between those findings by the two methods was significant (P<0.05).Conclusion: For diagnosing cirrhotic portal hypertension, the two methods were highly valuable with 100% sensitivity for the WHVP and more than 90% sensitivity for B mode ultrasound. Their specificity should be further studied.
