CEREBRAL ANGIOGRAPHY

(Latin cerebrum brain; Greek angeion a vessel + grapho to write, represent; a synonym an angiotserebrogra-fiya) — a radiological method of a research of vascular system of a brain by its artificial contrasting.

For the first time in clinic the angiography of vessels of a brain was executed in 1927 by A. Munish by administration of radiopaque substance in the general carotid artery, and in 1933 it made contrasting of vessels of vertebrobazi-lyarny system by administration of radiopaque substance in a vertebral artery.

The cerebral angiography allows to reveal tumors, arterial and arteriovenous aneurisms, a stenosis, thrombosis, an embolism and ruptures of brain vessels, volume inflammatory processes (abscesses, epidurita), infectious granulomas, nek-ry parasitic diseases of a brain (echinococcosis, cysticercosis), intracranial hematomas of a traumatic origin, the centers of a softening of a brain.

Distinguish the selection and total C. and. The selection cerebral angiography allows to contrast certain vascular pools of a brain. It can be made by separate administration of radiopaque substance in sleepy (see. A carotid angiography) and vertebral arteries (see Vertebralnaya an angiography) or their branches. The total cerebral angiography is applied extremely seldom to a survey research of hl. obr. large vessels of a brain by administration of radiopaque substance in an aortic arch.

Carrying out a catheter in the studied vessels at C. and. carry out under X-ray television control. C. and. carry out on special X-ray apparatus — the seriogra-fa allowing to make from 1 to 6 kraniogramm in 1 sec. Radiopaque substance is entered the automatic syringe according to the set program. At the selection C. and. the research is made usually in standard direct and side projections, and according to indications — in slanting and axial projections. At total C. and., to avoid projective stratification of brain vessels of both hemispheres in a side projection, carry out pictures in slanting projections.

Apply a pharmakoangiografiya with administration of vasoactive substances to obtaining the better image, use a method of subtraction (see), do pictures with pryakhmy blowup (makroangpografiya).

At C. and. the complications connected with intolerance of radiopaque substances (see) are possible. Besides, the spasm of brain vessels, an artherothrombosis in the place of its puncture and catheterization, a thromboembolism of vessels of a brain, epileptiform attacks can be observed. Treatment of these complications includes use of vasodilators (see), anticoagulants (see), the drugs changing rheological properties of blood, protivo to sou of road means (see) and also carrying out blockade of sympathetic nodes of a neck and a sinocarotid zone (see. Novocainic blockade).
