What it means
The renal arteries are a pair of blood vessels — one for each kidney — that branch off the aorta and carry oxygen-rich blood to the kidneys. Each kidney receives about twenty percent of the heart's output with every beat so it can filter the blood and produce urine. When a renal artery becomes narrowed — a condition called renal artery stenosis, usually caused by the buildup of plaque — blood flow to the kidney decreases, which can cause difficult-to-control high blood pressure and reduced kidney function. Doctors can diagnose this with imaging and sometimes treat it by widening the artery with a balloon and placing a stent to keep it open.
How to say it
Sentences a patient might use with a doctor, nurse, pharmacist, or insurer:

The CT angiogram will look at the renal arteries to see if they are blocked.
