Abstract:
Objective To explore the clinical value of the contrast-enhanced ultrasound (CEUS) in the diagnosis of renal artery stenosis(RAS).Methods A total of 20 patients(12 males and 8 females) including 40 renal arteries,who were suspected to have RAS were enrolled in Department of Renal,Beijing Hospital.All patients were examined by color doppler ultrasound,CEUS and digital subtraction angiography (DSA).The results of conventional ultrasound and CEUS were compared with the DSA results,respectively.Results All patients had history of hypertension,aged (65 ± 5)years.12 branches (mild 6,moderate 4,severe 2) were RAS by regular ultrasound,17 branches (mild 8,moderate 6,severe 3)were RAS by by CEUS,while 19 branches (mild 9,moderate 7,severe 3) were diagnosed as RAS by DSA.The measure of agreement Kappa between conventional ultrasound and DSA was lower than that between CEUS and DSA (0.77 vs.0.96,P＜0.01).The diagnostic accuracy of mild,moderate and sever RAS with CEUS were 88.9％,94.1％ and 100％,respectively.Conclusions CEUS shows the renal artery more clearly than conventional ultrasound,and has a high consistency with DSA in the diagnosis of RAS.
