Takayasu arteritis associated renal artery stenosis (TARAS) is the biggest cause of hypertension in young people <40 years old. Hypertension caused by renal artery stenosis is usually hard to control in spite of two or more anti-hypertension drugs.
Percutaneous transluminal angioplasty (PTA) is recommended for hypertension caused by TARAS. In previous clinical practice, we observed relatively effects of PTA on controlling the blood pressure in patients with TARAS. But, high re-stenosis rate was also indicated. Drug coated balloon (DCB）is a new type of PTA, which could improve the re-stenosis rate significantly. In the clinical trials of peripheral vascular disease, it has been confirmed that DCB had lower re-stenosis rate than PTA. However, up to date, no studies was found about the use of DBC in TARAS.
Thus, this study was design as a random, double blind trial to evaluated the effects and safety of DCB in the treatment of hypertension caused by TARAS.

A chronic inflammatory process that affects the AORTA and its primary branches, such as the brachiocephalic artery (BRACHIOCEPHALIC TRUNK) and CAROTID ARTERIES. It results in progressive arterial stenosis, occlusion, and aneurysm formation. The pulse in the arm is hard to detect. Patients with aortitis syndrome often exhibit retinopathy.
The use of balloon CATHETERS to remove emboli by retraction of the balloon that is inflated behind the EMBOLUS.

Widening of a stenosed HEART VALVE by the insertion of a balloon CATHETER into the valve and inflation of the balloon.
Counterpulsation in which a pumping unit synchronized with the patient's electrocardiogram rapidly fills a balloon in the aorta with helium or carbon dioxide in early diastole and evacuates the balloon at the onset of systole. As the balloon inflates, it raises aortic diastolic pressure, and as it deflates, it lowers aortic systolic pressure. The result is a decrease in left ventricular work and increased myocardial and peripheral perfusion.
