We did a prospective study in thirty one patients with ascites who were hospitalized at Cayetano Heredia Hospital (H.N.C.H.). We investigated the association and correlation between ultrasonographic parameters of portal hypertension (HTP) and the presence and level of HTP (determinate by the serum-to-ascites albumin concentration gradient). In our study, we demonstrated that ultrasonographic splenomegaly studied by longitudinal diameter of the spleen discriminate patients with HTP with a high positive predictive value (94.4%), although it didn't happen with transverse diameter of the spleen. However patients with elevated measurements of high GRAD-Alb (> or = 2.35 +/- 0.05 g/dl) had alterations in the transversal diameter of the spleen with a high negative predictive value (91.7%), these findings were suggested its use like a parameter for reject high levels of HTP. In our study, we demonstrated that the existence of changes at diameters of portal vein and splenic vein could not discriminate patients with HTP. By the way, we didn't find association between degree of high GRAD-Alb and the different splenic measurements.
我们对31例腹水患者进行了一项前瞻性研究，这些患者均在卡耶塔诺·埃雷迪亚医院（H.N.C.H.）住院。我们研究了门静脉高压（HTP）的超声参数与HTP的存在及水平（由血清-腹水白蛋白浓度梯度确定）之间的关联和相关性。在我们的研究中，我们证明，通过脾脏纵向直径研究的超声脾肿大对HTP患者具有较高的阳性预测值（94.4%），而脾脏横向直径则不然。然而，高GRAD-Alb（≥2.35±0.05 g/dl）测量值升高的患者脾脏横向直径有改变，具有较高的阴性预测值（91.7%），这些发现提示可将其用作排除高水平HTP的一个参数。在我们的研究中，我们证明门静脉和脾静脉直径的变化不能区分HTP患者。顺便说一下，我们未发现高GRAD-Alb程度与不同脾脏测量值之间存在关联。
