[Tomoangiography in neurosurgical clinical practice].

Abstract

The method of tomoangiography was developed on the "Neuroprincips" apparatus (of CGR company, France) provided with a simultaneous casset (7 films every 0.3--0.5 cm) that permits to obtain linear slides up to 2 mm thick in any phase of cerebral circulation, and in any plane and position of the patient. The examinations were conducted in 51 patients: 16 with saccular aneurysms, 9 with arteriovenous malformations, 7 with carotid-cavernous fistulas, 16 with brain tumours, 3 with orbital pathology. In 42 patients the carotid artery system was examined, in 6--the ventebrobasilar one, in 3--the venous system of the orbit, in 3--the zone of the cavernous sinuses. Tomoangiography provided additional information on the borders and depth of various pathological formations in the brain.
