Hypertension
About 10 percent of patients with high blood pressure have a narrowing of the artery to one or both kidneys, which causes their hypertension. This condition is known as renovascular hypertension.
Renal duplex, a sophisticated ultrasound technique, aids in the diagnosis of patients with renal artery stenosis. This noninvasive technology is useful in selecting patients for further evaluation and possible treatment. We often treat renovascular hypertension with angioplasty.
