Assessment of renal and hepatic hemodynamics in XXXX .

@entity1 @entity843 @entity1575
BACKGROUND AND OBJECTIVE: Investigators have documented an increase in renal artery resistance in cirrhotic @entity1 . We studied the hepatic and renal hemodynamics by color Doppler in @entity1 with @entity1575 in relation to the presence and severity of @entity843 . METHODS: A prospective study was carried out in a large public hospital on 33 @entity1 with @entity1575 and 11 healthy control subjects. Eleven @entity1 had no @entity843 , 12 had @entity843 and 10 had refractory @entity843 . The resistance index (RI) of the hepatic artery was measured by color Doppler on its main branch and renal artery RI was measured on the main renal, interlobar and cortical arteries of the right kidney. RESULTS: Considering intraobserver variabilities, coefficient of variation for RI was 2.3%-7.8% (mean [SD] 4.2% [1.8%]). Hepatic artery RI were 0.68 (0.07), 0.68 (0.1), 0.81 (0.04), 1.0 (0.12) in control subjects and cirhotics with no @entity843 , responsive @entity843 and refractory @entity843 , respectively. Renal RI was significantly higher than in control subjects at all three levels in @entity1 with responsive and refractory @entity843 , being higher in those with @entity843 . Renal RI decreased from hilum towards the outer parenchyma, in cirrhotics with no @entity843 and responsive @entity843 but not in refractory @entity843 . CONCLUSION: Hepatic artery RI is higher in cirrhotics and is related to presence and severity of @entity843 . In control subjects and @entity1 with no @entity843 or responsive @entity843 the renal RI decreased from hilum to the outer parenchyma.
