Peripheral Angiography

An angiogram is a study of arteries and veins of any part of the body using dye and xrays. It is performed to evaluate various vascular conditions, such as an aneurysm (ballooning of a blood vessel), stenosis (narrowing of a blood vessel), or blockages. It involves the insertion of a thin plastic tube (catheter) into the vascular tree. This is usually a small skin puncture into an easily accessible blood vessel in the hip region.
The tube is then navigated under Xray guidance through the vascular tree to the relevant blood vessel. Contrast (Xray dye) is then injected to opacify the blood vessel and a series of images are acquired.
Angiography is the gold standard to evaluate disease within the blood vessels. It is used to gather maximal information prior to any planned intervention. In many cases, as access to the relevant blood vessel is already achieved via minimally invasive means, some interventions such as angioplasty, stenting and embolisation can be performed at the same episode.
