摘要: No non-invasive test can predict the clinical outcome of renal revascularization procedures. Because duplex sonographic measurements intrarenal flow patterns reflect resistance to within kidney, prognostic value cortical end-diastolic peak systolic (d/s) velocity ratio was investigated in patients undergoing intervention for artery stenosis. The and data on 32 with 35 interventions (30 percutaneous transluminal angioplasties five operations) 42 sides were analysed. Twenty-three had atherosclerotic stenosis nine fibromuscular dysplasia resulting > or = 60% Measurements aortic d/s performed before after intervention. In patients, three clinically technically successful, eight successful but failures, 14 unsuccessful. two difference between corresponding ratios significant both treated not-treated (P < 0.02, two-tailed unpaired t-test). None 11 procedures a below 0.3, compared seven values 0.3 24 unsuccessful 0.05, one-tailed Fisher's exact test). It is concluded that: (1), correlates failure subsequent treatment hypertension by revascularization, while above has no significance; (2), despite technical success, not all have success from interventions; (3), failures are associated failures; (4), may be consequence more advanced age, longer duration additional risk factors patients.
