Abstract:
The study was conducted from January 1996 to March 1998 in B¹ch Mai Hospital. Participants were 100 hypertensive patients who have suspected renal artery stenosis after screening using clinical examination. Age of participants ranged from 9 to 50. All participants underwent colour ultrasonography and measurements are evaluated. Results showed that among 18 renal arteries of 9 patients, who received ultrasonography and angiography, 10 arteries were stenosed or occluded. 1 renal artery had suspected stenosis showed in ultrasonography, but not in angiography. So Doppler ultrasonography produced 1 false positive result, 10 true positive results, 7 true negative results and none false negative. This procedure gave high 100% of sensivity, 87.5% of speciality, positive prediction value is 90.9%, negative prediction value is 100%. Doppler ultrasonography can be used for post-operative examination and for patient following-up
