Abstract:
Objective
To analyze the interventional therapeutic effects in renal artery stenosis(RAS)disease.
Methods
Forty-five cases of RAS from March 2003 to March 2008 were admitted in our hospital.Fifty-three renal arteries were found stenosis or obstructed.Of those 11 arteries received percutaneous transluminal angioplasty (PTA)treatment,and other 42 arteries received PTA and stent planting treatment.The cases were followed up in blood pressure,serum creatinine and renal artery colour Doppler for 9 to 48 months.
Results
All the interventional operation of 45 cases were successful.After operation,the hypertension disappeared in 9 cases,improved in 28 cases,and the renal function improved in 12 cases.The effective rate of hypertension improving was 100%in fihromuscular dysplasia and takayasu disease group,which was much higher than 65.1%of atherosclerotic group (P＜0.05).Eighteen arteries were followed up by colour Doppler,and found restenosis in 7 cases.
Conclusion
The operation of PTA and PTA/stent provides a micro-trauma,safe and effective choice for therapy of RAS disease.
