Indication:

①Hypertension, if the upper limb blood pressure can not be measured, refer to lower limb blood pressure level;

②Unilateral or bilateral renal artery trunk or its main branches, lumen stenosis is greater than 50%, without obvious renal atrophy;

③The distal systolic pressure difference of renal artery stenosis is greater than 30MMHG or the mean pressure difference is greater than 20MMHG;

④The unilateral renal artery stenosis is more than 1.5 RVRP and the contralateral renal vein inferior vena cava distal PRA/ PRA1.3;

⑤There is no calcification in renal artery;

⑥Can not tolerate surgery. The above indexes should be comprehensively analyzed from two aspects of contrast, morphology and function so as to correctly select the indications for expansion. If the opening of the renal artery is completely obstructed or the distal branch has multiple stenosis or severe atrophy of the renal side of the ischemic side, it is not appropriate to do PTRA.

Treatment: the purpose of the treatment is to correct renal vascular hypertension and prevent renal failure. The curative effect of dilatation is closely related to the cause of disease. The renal artery fibrous muscle structure is bad, the curative effect is the best, the cure or improvement is 95.5%, the next is Takayasu arteritis 84%, and the atherosclerosis is only 54.5%.
