Arteriography
Arteriography (Greek aer - air + Greek tereo - contain + Greek grapho - to depict, write) - X-ray examination of the arteries, carried out after the introduction of a contrast agent into their lumen.
The following types of arteriography are distinguished:
- Catheterization - the contrast agent enters through a vascular catheter inserted into the artery;
- Open - a contrast agent is injected by puncture of an artery that has been previously exposed by surgery;
- Puncture (synonym: closed arteriography) - contrast agent is injected by puncture of the artery through the skin;
- Retrograde - puncture arteriography, when a contrast agent is injected under pressure against the bloodstream;
- Selective - a contrast agent is injected through a catheter directly into the artery under study;
- Spinal - arteriography of the vessels of the spinal cord; the contrast agent is injected directly into the aorta or selectively into the intercostal, lumbar arteries or in the branches of the subclavian artery;
- Cerebral - cerebral arteriography; it is used for diagnostic purposes for tumors, traumatic, vascular and other brain lesions, as well as for studies of cerebral circulation;
- Cerebral carotid - cerebral arteriography, when a contrast agent is injected into the common or internal carotid artery;
- Selective cerebral - cerebral arteriography, when the internal carotid and vertebral arteries are separately contrasted, this makes it possible to study the basins of these vessels, regardless of one another;
- Cerebral total - cerebral arteriography, when a contrast agent is injected into the ascending aorta, it allows one to simultaneously contrast the basins of all arteries that supply the brain.
