[Radionuclear encephalo-angioscintigraphic studies in transitory disorders of brain circulation in childhood].

Fifteen cases of transient cerebral ischaemia in children have been studied. Radionuclear encephaloangioscintigraphy (RNEAS) with Tc99 DTPA in combination with CT scanning, doppler sonography of extracranial head arteries and EEG were performed in all observed cases. For some children cerebral angiography was done. RNEAS study found out: stenosis of internal carotid artery or a. cerebri media in 5 cases; AV-malformations- 3; ischaemic area- 1, aneurysma- 1; increased blood permeability of the late static scintigraphy- 3. Positive correlation was established between the angioscintigraphic and sonographic findings in the cases with stenosis of internal carotid artery; between angioscintigraphic and CT results in the cases with ischaemia; between RNEAS and angiographic data in cases with AV-malformations, aneurysm and stenosis. In conclusion RNEAS could be considered as a useful, atraumatic screening method within the complex of laboratory examinations for vascular diseases in childhood.
