74 patients with ischemic cerebrovascular disease in patients with clinical analysis of carotid artery ultrasound

Were 8 cases of cerebral lesions, lesions in the carotid artery territory. Were associated with carotid artery disease in the same side, 1 case of ipsilateral posterior cerebral artery territory of massive cerebral infarction. 21 cases of TIA in 4 cases found lesions or cerebral malacia to the main lacunar lesions, the incidence of non-responsibility of both lesions. 3 Discussion 'carotid atherosclerosis is recognized as important in ischemic cerebrovascular disease risk factors, reported in the literature, 2O a 3O ischemic cerebrovascular disease and carotid atherosclerosis in the [1. Through our 74 patients with ischemic cerebrovascular disease in elderly patients with carotid artery ultrasound examination revealed that carotid atherosclerosis was 62%, and the January 2003 No. 1 s z ChinJCliMedPea. JanZOO31!!! In the occurrence of lacunar infarction group was 73.68. With atherosclerosis was significantly correlated. The first group had significant difference. The second group showed no significant difference. Generally believed that carotid atherosclerosis and carotid artery thromboembolic stroke and TIA, the main reason,[link widoczny dla zalogowanych], but the main cause of lacunar infarction is minimal atherosclerosis and arterial hypertension lipid small hyaline degeneration. Lead to cerebral artery branch occlusion of deep perforating branches of [2】. In this study,[link widoczny dla zalogowanych], the patients with lacunar infarction 73.68 with varying degrees of carotid artery atherosclerosis. 12 cases of soft plaque and plaque-prone plaque ulceration in 4 cases and 5 cases of carotid artery stenosis,[link widoczny dla zalogowanych], 1 case of bilateral internal carotid artery severe stenosis of 8O. Prompt carotid atherosclerosis and lacunar infarction have significant correlation. CME has been included in the reasons for the formation of cavities in a small number of serial sections revealed that the compartment in the. Shows the dominant cerebral artery area is normal. Microemboli may be derived from elsewhere [3】, a group of 23 foreign research data will be due to cerebral infarction in carotid atherosclerotic lesions, which l2 is lacunar infarction. Pathological studies have found that domestic lacunar infarction patients with carotid atherosclerosis. Lacunar infarction and cerebral infarction in a large degree of comparison, the average carotid artery stenosis. The difference was not significant. That the instability can be a small plaque off one of the causes of lacunar infarction】. Our results support this view. Table 1 carotid atherosclerosis and ischemic cerebrovascular disease group 3 the relationship (for example) x2 = 11.17p> O. 05 Table 246 cases of carotid atherosclerosis and ischemic cerebrovascular disease 3 groups of relations (cases) p> 0.05 Table 3 lacunar infarction group. Atherosclerotic thrombotic cerebral infarction group comparison of carotid atherosclerosis in carotid ischemic cerebrovascular disease caused by a variety of mechanisms: (1) increasing atherosclerotic plaque. Directly block blood vessels. Plaque instability. Distal embolization of plaque rupture of blood vessels; (2) rupture or rupture of the spot surface roughness, platelets and coagulation factors are activated,[link widoczny dla zalogowanych], the formation of thrombus; (3) stenosis of the carotid artery to the distal perfusion pressure fell. Lead to insufficient blood supply watershed areas. The formation of marginal or low perfusion with infarction infarction [5th. The pathogenesis of both the internal carotid artery thrombosis the incidence of cerebral infarction and TIA based on the formation of microemboli after shedding may also cause cerebral artery occlusion caused by deep perforating branches of lacunar infarction. We believe that carotid atherosclerosis is not only the atherosclerotic thrombotic cerebral infarction and carotid systems an important cause of TIA, but also led to an important reason for lacunar infarction. Carotid ultrasound non-invasive, safe, economical and practical. Above average in many hospitals has become popular. In particular, color Doppler ultrasound is able to carotid atherosclerosis in a reliable analysis of judgments. For the prognosis of ischemic cerebrovascular disease and clinical intervention therapy. Carried out as a neurological cerebrovascular disease prevention and control of conventional testing methods.
