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

The examination plan included: CT brain scan, magnetic resonance imaging (MRI), brain scintigraphy (SG), rheoencephalography (REG), cerebral multi-gated angiography (MUGA), laboratory tests, assessment of severity of dementia (CDR), cognitive impairment (MMSE) and activities of daily living (IB). 93 patients suffered extensive ischemic stroke of whom 7 (7.53%) had 10 - 15 IB points, 25 (26.88%)—20 - 30 IB points, 61 (65.59%)—35 - 45 IB points. 69 patients underwent transcatheter treatment (Test Group). 24 patients underwent conservative treatment (Control Group). High-energy laser systems were used for revascularization of major intracranial arteries;lowenergy laser systems were used for revascularization of distal intracranial branches. Test Group: 67 (97.10%) patients had good immediate angiographic outcome manifested in the restoration of lumen and patency of the affected vessels as well as in collateral revascularization. 12 - 24 months later the following positive trend was observed: 14 (20.59%) patients demonstrated good clinical outcome (IB 90 - 100);26 (38.24%) patients had satisfactory clinical outcome (IB 75 - 85);28 (41.18%) patients showed relatively satisfactory clinical outcome (IB 60 - 70);relatively positive clinical outcome (IB < 60) was not obtained in any case. Control Group: 4 (16.67%) patients showed relatively satisfactory clinical outcome (IB 60 - 70), relatively positive clinical outcome (IB < 60) was achieved in 20 (83.33%) cases. 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 extensive ischemic strokes. The effect is maintained for a long time;it causes regression of mental, intellectual and motor disorders, promotes regression of post-s展开更多
