[The potentials of current methods for the radiodiagnosis of cerebral arteriovenous malformations]. / Vozmozhnosti sovremennykh metodov luchevoi diagnostiki arteriovenoznykh mal'formatsii golovnogo mozga.

The potentialities of current Neuroimaging methods were established to allow one to make an early minimally invasive diagnosis of arteriovenous [correction of arterioventricular] malformations. The most promising method is a combined use of X-ray computer and magnetic resonance tomography with transcranial Doppler echography, which is in conformity with the unity principle of morphological and functional non-invasive diagnostic methods. At present, cerebral angiography should be used only in combination with preoperative examination of these patients.

Fifteen patients with volumetric abnormal formations of the brain stew were studied. All the patients underwent craniography and computed tomography (CT); magnetic resonance tomography (MRT) and cerebral angiography were conducted in 6 and 8 patients, respectively. The studies provided a full-value differential diagnosis and revealed the following abnormal changes: brain stem tumors in 8 patients, intratruncal hematomas in 6, and arteriovenous malformations in. 1. MRT was ascertained to be the most informative technique in the diagnoses of volumetric abnormal formations. The advantage of MRT over CT is not only to obtain three-dimensional tomograms, but to use various pulse sequences, allowing for a valid differential diagnosis of tumors and intratruncal hematomas. MR angiography is a promising trend in the diagnosis of tumors and vascular malformations.

[The diagnosis of arteriovenous malformations of the brain by transcranial dopplerography (the potentials of complex noninvasive neurosonoradiological diagnosis)]. / Diagnostika arteriovenoznykh mal'formatsii golovnogo mozga metodom transkranial'noi dopplerografii (vozmozhnosti kompleksnoi neinvazivnoi neirosonoradiologicheskoi diagnostiki).

Under analysis were results of diagnostics in 89 patients with suspected arteriovenous malformations (AVM) obtained by the method of ROC-analysis. The examination included computed tomography (CT) and transcranial dopplerography (TCDG) performed by the standard method. The total sensitivity of TCDG in diagnosing AVMs as a nosological form was 89.5% which is considerably higher than the possibilities of CT. Malformation having a torpid course were diagnosed correctly reliably more often (100%) than those with hemorrhagic debut (78.6%). Most perspective is the principle of unity of "morphological" and functional methods of noninvasive diagnostics. Sensitivity of the complex diagnostics of AVMs was 92.9%, diagnostics of malformations with a torpid course being without errors.

Under study was the clinico-roentgenological dynamic of the lung state in 79 patients with severe cranio-cerebral trauma. High continuous peridural blocade performed from the moment of admission to the hospital was shown to prevent the development of hard reactive alterations in the lungs. This method however fails to control acute severe aspiration pneumonia.
