The examination plan included: computed tomography of the brain (CT), magnetic resonance imaging (MRI), scintigraphy of the brain (SG), rheoencephalography (REG), cerebral multi-gated angiography (MUGA). 665 (59.11%) patients suffered from diseases accompanied by the development of vascular dementia. To perform transcatheter treatment, 639 patients were selected: Group 1 (CDR-1)—352 patients, Group 2 (CDR-2)—184 patients, Group 3 (CDR-3)—103 patients. To conduct revascularization of main intracranial arteries high-energy laser systems were used;for revascularization of the distal intracranial branches low-energy laser systems were used. The clinical outcome depended on the severity of dementia and the timing of the intervention. A good clinical outcome in Group 1 was obtained in 281 (79.82%) cases, in Group 2 in 81 (44.02%) cases, in Group 3 in 9 (8.73%) cases. A satisfactory clinical outcome in Group 1 was obtained in 53 (15.34%) cases, in Group 2 in 62 (33.70%) cases, in Group 3 in 31 (30.09%) cases. A relatively satisfactory clinical outcome in Group 1 was obtained in 17 (4.83%) cases, in Group 2 in 41 (22.28%) cases, in Group 3 in 63 (61.16%) cases. No negative effect was observed after the intervention. Evaluating the data obtained it can be concluded that the method of transluminal laser revascularization of cerebral blood vessels is an effective one for the treatment of atherosclerotic lesions of the brain accompanied by dementia.展开更多
