During 4/1998 -4/1999, the HuÕ Central Hospital implemented the spiral CT scanner for 8 cases with ages of 17 - 79 to diagnosed the renal arterial stenosid after implementing the ultrasound Doppler and angiography of the renal artery. The result have shown that the spiral CT scanner is able to discover the spited artery with the very thin wall and observe the false arterial lumen and virtual arterial lumen. The cross-sectional reconstruction can identify obviously the border of the arterial lumen, position of stenosid, artherosclerosis plaque, thrombosis that helped the diagnosis and treatment.
Angiography ; Renal Artery Obstruction

9 patients received the angiography found 10 renal arterial stenosid or obstruction among 100 patients during 1/1995 - 3/1998. The results showed that the level of the arterial stenosid by ultrasound was quite suitable with this by the angiography. All patients received an operation for connecting the renal artery or thrombosis removal were postoperative examined by the color ultrasound Doppler and long-term monitored.
Ultrasonography ; Renal Artery Obstruction

Nowadays, diagnosis of renal artery stenosis by renal angiography is gradually supplied by techniques of noninterference, include: Colour Doppler ultrasound, CT angiography in helical with MIP, magnetic resonance angiography. In the all, the colour Doppler ultrasound is the best method for diagnosis of renal artery atenosis in the near future

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

Polycythemia Vera* ; Renal Artery Obstruction*

Extra-adrenal pheochromocytoma accounts for about 10 to 15 percent of all such tumors and the combination of pheochromocytoma and renal artery stenosis is rare. We report an unusual case of extra-adrenal pheochromocytoma causing renal artery stenosis which was developed in a 11-year-old boy and the literatures were reviewed.
