Abstract

PURPOSE: To evaluate 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. MATERIALS AND METHODS: The intraparenchymal renal resistive index (RI) (reference value, 0.7) in 18 (36%) patients and was normal in 32 (64%). The proportion of patients with varices was significantly higher in the former group: 14 (78%) versus 10 (31%) (P = .002). In detection of the presence of varices, the renal RI was uniformly better than the portal congestive index in terms of sensitivity (58% vs 48%), specificity (84% vs 54%), and positive (3.60 vs 1.04) and negative (0.50 vs 0.96) likelihood ratios. RI determination improved the ability to exclude the presence of varices from a basal pretest probability of 52% (26 of 50 patients) to a final one of 69% (22 of 32 patients) and that of predicting the presence of varices from 48% (24 of 50 patients) to 78% (14 of 18 patients). CONCLUSION: A substantial proportion of patients with Child-Pugh class A cirrhosis without ascites have increased renovascular impedance; this significantly correlates with the presence of varices.
