PERCUTANEOUS TRANSLUMINAL ANGIOPLASTY FOR RENOVASCULAR HYPERTENSION IN ARTERITIS; EXPERIENCE IN THAILAND

Abstract

PURPOSE To evaluate the result of the treatment of the percutaneous transluminal angioplasty (PTA*) for renovascular hypertension in arteritis.
MATERIAL and METHODS There were 14 patients, 8 males, 6 females, age 18-53 years, mean 31 years. Five patients had bilateral renal artery stenosis. But PTA was performed in both renal arteries in only 1 case. The transfemoral route was used to treat 14 stenoses, except one patient who had complete aortic occlusion, transaxillary route was used. The PTA was performed, by exchange balloon catheter technique. Follow-up examination included blood pressure, renogram, and medication evaluation.
RESULTS Technical success rate was obtained in 14 lesions (93%) in 13 pa- tients (93%). Only one failure occured in the very tight proximal stenosis of the renal artery. Clinical sucess rate was 88 % (improvement of hypertension, or discontinue medication). No complication was occured except there was temporary spasm/throm- bosis of renal artery in one case (7%).
CONCLUSION The renal angioplasty in non-specific arteritis (Takayasu's arteritis) is effective and safe procedure. The results are good, and there is low accept- able complication. There is no long -term follow up examination.
