ABSTSESSOGRAFIYA (abscess + Greek grapho — I write, I represent) — X-ray inspection of the created abscess after artificial contrasting of his cavity. It can be used for studying of abscesses of various localization — in a brain, lungs, a liver, subphrenic space. And. allows to define location, size, a form and a condition of an inner surface of abscess (see).
The research is conducted in several stages. In the beginning, being guided by clinical and radiological data, establish localization of an abscess. Then make a puncture of abscess, suck away from it contents and supersede in an abscess cavity gas (nitrous oxide, oxygen, air) or a high-atomic contrast agent (50% solution of Hypaque, mayodit) then carry out television roentgenoscopy and a X-ray analysis in necessary projections.
Due to the development of other ways of artificial contrasting, first of all arteriography (see), and also radio isotope scanning, to And. resort seldom. This technique kept a nek-swarm value in neurosurgery. If clinical methods do not allow to distinguish and localize precisely abscess of a brain, use arteriography) and a ventrikulografiya (see) and then, in the presence of indications, A.
Punktion of a brain is made through the trepanation opening imposed in the field of estimated abscess, and at children of early age through not closed fontanels or the gaping seams. After extraction of pus and administration of gas or a mayodil do roentgenograms at different provisions of the head of the patient: side (fig. 1), at situation up (fig. 2) or facedown and the horizontal course of a bunch of x-ray emission and a straight line (fig. 3).
And. a brain allows not only to specify localization, the sizes, a form, character of an inner surface of a cavity, but also to reveal its communication with likvorny spaces of a brain. In the latter case there is a penetration of a contrast agent into ventricles and a subarachnoid space. Bibliography: Irger I of M. Neurosurgery, M., 1971; Kopylov M. B.
