Objective:
To observe the changes of clinical characteristics and interventional methods of patients with renal artery stenosis in recent 17 years.
Methods:
Comparing the clinical characteristics and interventional treatment of patients diagnosed renal artery stenosis by the means of renal angiography in recent 17 years.
Results:
The numbers of renal artery stenosis were increasing year by year. the average ages before the year of 2000 was younger than that after 2000 (P < 0.05) and the main cause of renal artery stenosis was aorto-arteritis at that time, however, it turned to atherosclerosis after the year of 2000. Same patients indicated renal angiography due to plash pulmonary edema, unstable angina on abnormal serum creatinine. The interventional methods to renal artery stenosis shifted from balloon angioplasty only before the year of 2000 to stent implantation post-balloon dilatation after the year of 2000. The distal protective device was more used during the procedure.
Conclusions:
The numbers of patients indicated renal angiography had been increasing in the two decades. The main causes of renal artery stenosis had been considered arthro-sclerosis instead of aorta-arteritis before. The methods of treatment to renal artery stenosis had been changed to renal stenting post-balloon angioplasty after the year of 2000.
