Looking inside blood vessels to diagnose blockages and other abnormalities.
Angiography is a procedure that uses x-rays to provide pictures of the inside of blood vessels. This procedure shows blockages, narrowing, aneurysms (ballooning) and other blood abnormalities.
How Long Will it Take?
- Angiography usually takes about an hour and the catheter is removed.
How Does the Procedure Work?
- An I-V (intravenous) line in the patient’s arm allows the radiologist to administer fluids and a sedative, if necessary.
- Local anesthesia is applied to numb the area where a small incision is made.
- A small tube called a catheter is inserted into an artery in the leg at the area.
- The radiologist guides the catheter through the blood vessels by watching its progress on a video monitor that displays the x-rays (flouroscope).
- Once the catheter is in place, a contrast agent (like a dye) is injected. This allows the radiologist to see the blood vessels on the monitor.
- Photos are taken. Patients will hold their breath for a few moments to ensure clearer pictures.
- The catheter may be moved to another area and the procedure repeated.
After the Procedure
- While in outpatient recovery (about 4 hrs), we will carefully monitor blood pressure, pulse & area.
- Drink plenty of fluids. Refrain from exercise & walking.
- Keep the bandages on for the next 24 hours, and do not shower for 12 hours.
- Contact the hospital if bleeding, unusual pain, or a temperature or color change occurs.
