Renal artery stenosis: duplex Doppler evaluation.

摘要: The renal arteries of 40 patients without or renovascular disease were examined with duplex real-time Doppler sonography. Special views employed to obtain adequate images and recordings from the arteries. Time limits placed on duration examination, better reflect common clinical practice. Velocity spectral analysis shift frequency was achieved in 82.5% a characteristic "Doppler signature" for artery identified. This compared signal eight stenosis. Significant differences pattern demonstrated These are illustrated their potential screening systemic hypertension is discussed.
