Imaging Studies VII: Vascular Imaging

A renal angiogram is an imaging test that examines the kidney's blood vessels, evaluates blood flow, and helps diagnose blockages, aneurysms, narrowing, or tumors.

Before the test, the nurse explains the procedure, obtains consent, checks for any contrast dye allergies, and advises fasting for 6-8 hours and emptying the bladder.

During the procedure, the patient is positioned supine on the imaging table, where an IV line is set up and a sedative is administered.

The femoral artery site is cleaned using aseptic techniques, and a catheter is inserted into the femoral artery and guided to the renal arteries using fluoroscopy.

Once in place, contrast dye is injected into the renal arteries, then the radiologist captures X-ray images of blood flow in arteries, capillaries, and veins.

Post-procedure, the radiologist removes the catheter and applies pressure to prevent bleeding.

In the recovery room, the nurse monitors vital signs, checks the insertion site, encourages fluid intake, and advises bed rest with the leg kept straight.
