目的探讨研究血清-腹水白蛋白梯度检测对诊断腹水性质的临床意义。方法本院自2005年10月至2008年10月收治的242例腹水患者以彩色多普勒超声测定门静脉内径>14mm提示门静脉高压,分为门静脉高压组130例和非门静脉高压组112例进行血清一腹水白蛋白梯度检测。结果门静脉高压组SAAG(17.8±4.7)g/L,符合率96.15%;非门静脉高压组SAAG(8.2±3)g/L,符合率95.53%。结论SAAG检测操作方法简单,与门脉高压相关性好,具有更强的实用性及更广泛的应用价值.有助于更容易鉴别积液的性质,在腹水病因诊断中具有重要的临床价值。
Objective To investigate the clinical significance of serum-ascites albumin gradient in the diagnosis of ascites. Methods A total of 242 patients with ascites admitted to our hospital from October 2005 to October 2008 were enrolled in this study. They were classified into portal hypertension group (n = 130) and non-portal hypertension group (n = 112) with color Doppler echocardiography. Ascites albumin gradient detection. Results The SAAG (17.8 ± 4.7) g / L in portal hypertension group was 96.15%. The non-portal hypertension group was SAAG (8.2 ± 3) g / L, with a coincidence rate of 95.53%. Conclusion SAAG has simple operation method, good correlation with portal hypertension, more practicality and wider application value, which is helpful to identify the effusion more easily and has important clinical value in the diagnosis of ascites.
