Summary: It is a diagnostic test , where contrast and X-ray machine is used to look for blocks in the arteries that supply blood to your heart. Basically it is a test to find out how many or how much block you have in these arteries.
Angiography is a medical imaging technique used to visualize blood vessels in various parts of the body. It is commonly employed to diagnose and evaluate conditions related to the blood vessels, such as blockages, aneurysms, and other abnormalities.
The procedure involves the injection of a contrast dye into the blood vessels, which makes them visible on X-ray or other imaging modalities.
Here’s an overview of the angiography process:
Preparation: Before the procedure, the patient may need to fast for a few hours, and the medical team will gather information about the patient’s medical history, allergies, and any medications they are taking.
Injection of Contrast Dye: The patient is positioned on an examination table, and a small catheter (a thin, flexible tube) is inserted into the blood vessels, usually through a small incision in the skin. The catheter is carefully threaded through the vascular system to the area of interest. Once in position, a contrast dye is injected through the catheter.
Imaging: As the contrast dye flows through the blood vessels, it highlights them on X-ray images or other imaging modalities like computed tomography (CT) or magnetic resonance imaging (MRI). These images help the doctor visualize the structure and function of the blood vessels.
Post-Procedure: After the images are captured, the catheter is removed, and the incision site is typically closed with a small bandage. The patient may be observed for a short period to monitor for any potential complications.
Angiography plays a crucial role in diagnosing and guiding the treatment of various vascular conditions, helping healthcare professionals make informed decisions about patient care.
