Hypertension remains one of the most common medical conditions. Although often easily controlled, some patients have severe hypertension that is difficult to control even with multiple medications. Although uncommon, renal artery stenosis is easily treatable with endovascular intervention. The first step in diagnosis of renal artery stenosis is a renal artery ultrasound to determine the amount of stenosis present. If stenosis is suspected on ultrasound a physician can proceed with conventional angiography or other imaging to determine the best course of treatment.
Ultrasound imaging does not rely on radiation to produce an image unlike other imaging modalities. Instead, ultrasound technology uses sound waves to determine both the anatomy and speed of blood traveling through the vessels. Unlike other types of imaging there is also no need for contrast, which can damage the kidneys.
The quality of any ultrasound image depends on multiple factors. These include the skill of the technician, the quality of the ultrasound machine, and the expertise of the physician reading the scan. Renal ultrasounds can be particularly difficult to perform in those patients with a large body habitus. Patients requiring a renal ultrasound should seek a physician with a “RPVI” certification. RPVI stands for registered physician in vascular interpretation. To achieve this certification physicians must provide proof they have had instruction in vascular ultrasound as well as pass an examination showing expertise necessary to interpret vascular ultrasounds.
