Angiography involves a specific medical procedure to visualize blood vessels. Here's how it's generally performed, according to the reference provided:
Angiography Procedure: A Step-by-Step Guide
-
Preparation: You will lie down on an X-ray table.
-
Anesthesia: A local anesthetic is administered to numb the area where a small cut (incision) will be made. This is usually near your groin or wrist.
-
Incision and Catheter Insertion:
- A small cut is made to access an artery.
- A very thin, flexible tube called a catheter is then inserted into the artery.
The following steps, which are implied though not explicitly detailed in the provided reference, complete the angiography process:
-
Catheter Navigation: The catheter is carefully guided through the arteries to the specific area that needs to be examined.
-
Contrast Dye Injection: A special dye (contrast agent) is injected through the catheter. This dye makes the blood vessels visible on X-ray images.
-
X-ray Imaging: As the dye flows through the vessels, a series of X-ray images are taken. These images show the structure and function of the blood vessels.
-
Image Review: The images are reviewed by a radiologist to identify any abnormalities, such as blockages or narrowing of the arteries.
-
Catheter Removal and Closure: Once the imaging is complete, the catheter is removed, and the incision site is closed with pressure, sutures, or a special closure device.
Important Considerations
- The specific steps and techniques may vary depending on the type of angiography being performed and the area of the body being examined.
