Abstract
The aim of this work was evaluation of the frequency of increased renovascular impedance and its relationship with the presence of esophageal varices in patients with Child-Pugh class A cirrhosis without ascites and the possibility of its use as a predictor factor of esophageal varices.
This study was done on 50 patients with child A liver cirrhosis attended to the outpatient clinic of endemic medicine department in Beni-suef university hospital.
All patients were subjected to complete history taking, thorough clinical examinations, laboratory investigations, abdominal ultrasonography and Doppler study of the portal and renal vessels. Upper endoscopy was done for all the patients.
In our study there is significant correlation between increase of RRI and presence of varices.
In our study the Sensitivity, Specificity, Positive predictive value and Negative predictive values of renal resistive index are 19.2, 95.8, 83.3 and 52.2 %.
In our study the Sensitivity, Specificity, Positive predictive value and Negative predictive values of portal congestive index are 7.6, 95.8, 66.6 and 48.9%.
There is no significant Correlation between splenomegaly and esophageal varices.
The Laboratory data analysis in the current study showed that there is no significant correlation between thrombocytopenia and presence of varices.
There is significant Correlation between Spider naevi and grading of esophageal varices while there wasn’t significant Correlation between Spider naevi and presence of esophageal varices.
There is significant Correlation between Splenic hilar collaterals and presence of esophageal varices and also with grading of esophageal varices.
