Abstract

Perutaneous Transluminal Angioplasty(PTA) is an effective initial treatment modality in renovascularhypertension. For determination of PTA effect, the pulse pressure recording of renal artery is not simple ascompared with in femoral artery stenosis. We tried to evaluate the PTA effect of renal artery stenosis withtracing the pressure of distal renal artery. We used the cardiac catheterization apparatus(VR-12 Honeywell) as apressure monitor in two cases of focal renal arterial stenosis. The renal artery pressure was doubled after firstattempt of ballooning, and the pressure elevated up to 94% and 79% of aorta pressure in two cases, respectively,after third attempt. We believe that renal artery pressure monitoring is a good method of determination of PTAeffect in renovascular hypertension.
