Aneurysm was the first disease of the renal artery to be recognized by Rouppe on 1770, and until selective renal angiography came into vogue, it was considered a rare occurrence. We had experienced 2 cases of renal artery aneurysm that one case was found intraoperatively by chance and the other was confirmed with selective renal angiography. We report 2 cases with review of the literature.

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.

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 renal arterial trauma is rarely lesion. Injured renal functions significantly depended on the early diagnosis and operation. The early UIV and ultrasound Doppler were selected to examine. The renal and vascular examination should be implemented to prevent from missing the lesion.

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

The measurement of parameter of the aorta, renal left and right arteries of 40 normal people with ages of 20 - 40 has shown that the parameters of indicators of Doppler in the normal Vietnamese were an insignificant different from these in normal English, French. The parameters of Vp, Vd and Vm were different between the left and right, and between proximal and distal position of the renal artery. The parameters of ACT, RI, PI, ATR, RAR were not different between right and left as well as position of the renal artery
