Information About the Field of Angiography
What is an aniography?
Angiography refers to a radiological examination which can make blood vessels of the human body visible. The principle involves an intravenous injection of a contrast medium followed by an X-ray or MRI examination. The objective of these exams is to illustrate contrast medium and thus the blood vessels. Depending on the indication, arteries (arteriography), veins (phlebography) or lymphatic vessels (lymphography) can be examined this way.
When and why is an angiography carried out?
Angiography is employed for diagnosing blood vessel disorders . Arteriography can give information about vessel stenosis due to atherosclerosis , which in turn may help to prevent secondary conditions such as myocardial infarctions or strokes. It may also reveal acute vascular occlusions, lesions or malformations. Also aneurysms , which is a dangerous outpouching of an artery, can be seen this way. Typically heart and brain are the organs to undergo examination.
During an angiography of veins, mostly the lower extremities are being examined. The goal of this test is to diagnose stenotic blood vessels that may lead to thrombosis .
Lymphographies are seldomly performed these days and originally served to examine lymph nodes. However, technically sophisticated imaging methods available are the better alternative.
Procedure of an angiography
Before an angiography, the treating physician has to investigate the patient’s blood values, provide an anamnesis and test for a potential allergy against contrast agents. Furthermore, renal insufficiency and hypothyroidism need to be excluded. Afterwards, the patient is administered a contrast medium via a catheter, which is pushed forwards until the vessel in question is reached.
This body area is then assessed by an imaging method such as ultrasound, X-ray, computer tomography or magnetic resonance imaging (CT or MRI). The so-called digital subtraction angiography (DSA) is a new method, which involves taking digital pictures before and after administering a contrast agent. A computer software will be used to compare both sets of images and delete all identical pictures. This way, only the vessels filled with contrast medium are shown.
Risks associated with angiography
Angiographies are routine examinations. Serious complications are very rare, as thorough pre-testing is mandatory. Just like after any injection, hematomas and blood clots as well as infections are possible. Following the administration of a contrast agent, many patients may experience a sensation of warmth, mild dizziness or an unusual taste. This is very normal and not dangerous, though.
Generally, an angiography is carried out in an outpatient way and patients are allowed to go home right after. However, it is still recommended to rest the next day and drink lots of fluids, as this will speed up the metabolism of the contrast medium.
