It is recommended in several conditions such as cerebrovascular disease, peripheral vascular disease, and heart disease etc. Here, a catheter is inserted into the blood vessels and a contrast dye is injected into the veins. Later several X-ray images will be taken and based on the images, your doctor will diagnose the disease and a treatment plan will be made.
There are several types of Angiography and they are
- Coronary Angiography
- Pulmonary Angiography
- Renal Angiography
- Radionuclide Angiography
- Digital Subtraction Angiography
- Magnetic Resonance Angiography
- Cerebral Angiography
- Right or left heart ventriculography
- Aortic Angiography
- Eye Angiography
What are the advantages of Angiography?
- It provides accurate images of the internal blood vessels and arteries.
- It helps in diagnosing specific diseases.

- Now, the catheter is slowly directed throughout the artery until the tip reaches the vessel that needed to be examined.
- Then, a contrast dye is injected into the blood vessel through the catheter. This dye will help the blood vessels to view on the X-ray images.
- X-rays of the blood vessels will be taken.
- Later the catheter will be removed from the large artery.
- Your doctor will review the X-ray images to determine the problem.
What is the postprocedure care/recovery care for Angiography?
- After the completion of the procedure, you may need to stay in the hospital until you are awake from the sedation.
- Then, your doctor will provide some instructions regarding postprocedure care.
- If there is a pain at the site of catheter insertion, then consult your doctor.

- If bleeding is seen at the cut, consult your doctor as soon as possible.
- There may be some complications and risks after the procedure. So, follow all the instructions and directions provided by your doctor.

What are the long-term results of Angiography?
There are no specific long-term results of Angiography. However, people who undergo Angiography may suffer from minor complications.
Can Angiography be detected in the future?
