Clinical utility of the resistive index in atherosclerotic renovascular disease

摘要: Objective This retrospective study examines the relationship between renal resistive index (RI) and blood pressure function response after open percutaneous intervention for atherosclerotic renovascular disease (AS-RVD). Methods From March 1997 to December 2005, 86 patients (46 women, 40 men; mean age, 68 ± 10 years) underwent duplex sonography (RDS), including main artery hilar vessel Doppler interrogation, before treatment of AS-RVD. Of these, 56 had operative repair, 30 intervention. The RI (1–[EDV/PSV]) was calculated from kidney with highest peak systolic velocity (PSV). Hypertension graded preprocedural postprocedural measurements medication requirements. Renal by a ≥20% change in estimated glomerular filtration rate (eGFR) serum creatinine concentration. Results Comorbid conditions, baseline pressure, preoperative were not significantly different groups. Baseline characteristics that differed vs group higher age (71 11 years 67 9 years; P = .05), length (11.3 1.3 cm 10.7 1.2 cm; .02), proportion ≥0.8 (50% 21%; .01), bilateral AS-RVD (37% 80%; .003) ( .008) considered. Specifically, eGFR declined preprocedure postprocedure repair analyzed as whole. Neither nor diastolic demonstrated an association RI. Considering all both groups, multivariable proportional hazards regression models predictive all-cause mortality. most powerful predictor death during follow-up (hazard ratio, 6.7; 95% confidence interval, 2.6-17.2; Conclusion After AS-RVD, associated function, but response. A strong, independent mortality observed
