Angiography risks you should be aware of
Many patients with cardiovascular sickness are asked to undergo an angiography. It is a process that identifies the number of blockages in your coronary arteries and assesses the severity of your heart disease. It helps doctors make a decision on the further line of treatment.
Who needs an angiography and can everyone undergo it?
It is complete on people who have coronary artery disease and can be successfully performed on children as well as the elderly. In infants and children, it is generally performed to identify any congenital heart disease or valve problems. However, it cannot be performed on people with weak hearts and poor blood pumping capacity or kidney disease. You may like to read about what to expect during an angiography.
How safe is it?
Angiography is an invasive process and the risk associated with it is as small as 1%. However, there are a few risks like:
- An allergy to the dye that reason urticaria or angioedema.
- Bleeding and local blood collection at the site of injection.
- At times, an angiography may need extra fluid administration, and a fluid overload may cause congestive heart failure. Vomiting might also occur, harming the lungs.
- Flaring up of asthma.
- Sometimes, the dye can reason serious problems to the kidney and the patient might have to undergo dialysis too.
How Does Angiography Work?
Angiographic x-ray imaging has grown into its own classification of x-ray imaging over time. The basic principal is the same as a conventional x-ray: x-rays are generated by an x-ray tube and as they pass through the body part being imaged; they are attenuated at different levels. These differences in x-ray attenuation are then measured by an Image Intensifier and the resulting image is picked up by a TV camera. In modern angiography systems, each frame of the analog TV signal is then con verted to a digital frame and stored by a computer in memory and/or on hard magnetic disk. These x-ray “movies” can be viewed in real time as the angiography is being performed, or they can be reviewed later using recall from digital memory.
