Why is an angiography done?

Written by : DoctorNDTV Team

Angiography is used to detect abnormalities or blockages in the blood vessels throughout the circulatory system and in some organs. The procedure is commonly used to identify atherosclerosis; to diagnose heart disease; to evaluate kidney function and detect kidney cysts or tumours; to detect an aneurysm (an abnormal bulge of an artery that can rupture leading to haemorrhage), tumour, blood clot, or arteriovenous malformations in the brain; and to diagnose problems with the retina of the eye. It is also used to give surgeons an accurate ‘map’ of the heart prior to open-heart surgery, or of the brain prior to neurosurgery.
