Brain aneurysm surgery: twenty years experience of the Republican research center of emergency medicine

Abstract

Aim. To study the twenty years’ experience of the RRCEM in providing neurosurgical care to patients with
cerebral arterial aneurysms (AA).
Material and methods. The results of examination and treatment of 282 patients with AA hospitalized
in the Department of neurosurgery of the RRCEM in the period from 2001 to 2020 were studied. A total
of 271 patients were operated on, including 146 (53.9%) with AA ruptures, 125 (46.1%) without rupture. Operations with 3D reconstruction of the cerebral vascular bed were performed in only 239 (88.2%)
patients.
Results. AA is more often localized in the basins of the medial cerebral artery (64.5%), baggy forms of
aneurysm (93.3%) of medium size (69.1%) prevail. AA ruptures are more often observed in the basins of
the medial (32.9%) and anterior (32.1%) arteries. The use of AA focal clipping allows to achieve a favorable outcome (OGS I and II) in 66.9% of cases.
Conclusion. Focal clipping of AA using MSCT 3D modeling of angioarchitectonics of the brain allows radical and safe elimination of aneurysm with minimal traumatization of surrounding tissues.
