RATIONALE AND OBJECTIVES: To analyze changes in Doppler ultrasound variables in relation to liver biopsy findings for the diagnosis of acute rejection after orthotopic liver transplantation (OLT), the authors performed in a prospective study 316 Doppler ultrasound examinations in the first 2 weeks after OLT on 23 patients. METHODS: Recordings were obtained daily from the hepatic artery (resistive index [RI]) and hepatic vein (damping index [DI]). Correlations were explored between the Doppler ultrasound findings and histologic data. The chi-square test was used to analyze differences in Doppler ultrasound variables in patients with and without acute rejection. RESULTS: Serial Doppler ultrasound examinations showed a significant increase in the RI in 11 of 22 patients (50%); the 23rd patient was excluded because of hepatic artery thrombosis. Despite an agreement in 15 of 22 patients (68%) no statistically significant correlation could be found (positive predictive value 6/11 = 55%; negative predictive value 9/11 = 82%; chi-square = 3.14; P > 0.05). A significant increase in the DI was observed in 14 of 23 patients (61%). However, no statistically significant correlation could be found as well with this parameter (positive predictive value 6/14 = 43%; negative predictive value 6/9 = 67%; chi-square = 0.00; P > 0.05). CONCLUSION: Serial Doppler ultrasound examinations were not helpful in predicting acute rejection.
