Risk Factors And Clinical Characters Of Thalamic Stroke

Objective To investigate the risk factors,clinical characters,medical complications,cause of disease and the prognostic condition in thalamic stroke.Inorder to provide clinical accordance with which we can be used to manage high risk group,prevent recurrence and improve the primary prevention of stroke.Methods Choose 32 cases impatient cared thalamic infarction patients in the first affiliated hospital of Guangxi Medical University from January 1,2007 to January 1,2009,concurrently choose 30 cases thalamic hemorrhage patients in the same period as the thalamic infarction group as contrasting group.Basic clinical information of each patient was analyzed.All data were analysed by chi-Square test or independent-sample T-test with SPSS13.0 software.Results(1) There were 43 men and 19 women among 62 patients,age from 40 to 86,mean age:61.25±11.29 years old.(2) The proportion hypertension was 56.3%for thalamic infarction versus 80.0%for thalamic hemorrhage with significant difference(P＜0.05).The proportion hyperfibrinogenemia was 46.9%for thalamic infarction versus 20.0%for thalamic hemorrhage with significant difference(P＜0.05). The proportion diabetes mellitus was 46.9%for thalamic infarction versus 16.7%for thalamic hemorrhage with significant difference(P＜0.05).(3) The proportion atherosclerosis was 84.4%for thalamic infarction versus 60.0%for thalamic hemorrhage with significant difference(P＜0.05).(4) The thalamic hemorrhage patients often got a disease in the activity,and headache,vomiting,conscious disturbance, disturbance of intelligence,disturbance of sphincter and meningeal irritation sign were higher than proportion taken up by thalamic infarction patients with significant difference(P＜0.05).(4) The proportion complications of infection was 18.8%for thalamic infarction versus 46.7%for thalamic hemorrhage with significant difference(P＜0.05).(5) Thalamic infarction in patients improved in 30 cases after treatment,no change in 1 case,the deterioration in 1 case.Thalamic hemorrhage patients improved after treatment in 25 cases,no change in 1 case, deterioration in 4 cases.The Comparison of two groups of prognosis has not significant difference(P＞0.05).Conclusion(1)The factors for thalamic infarction and thalamic hemorrhage were not the same.Hypertension was the crucial risk factor of thalamic hemorrhage.Hypertension,diabetes mellitus and hyperfibrinogenemia are crucial risk factors of thalamic infarction. (2) The cause of disease for thalamic infarction and thatamic hemorrhage is not the same.Atherosclerosis is the crucial cause of disease of thalamic infarction.(3) Characters manifestation of thalamic hemorrhage includes disturbance of consciousness,increased intracranial pressure,gaze palsy,meningeal irritation sign.(4) The infection complications of thalamic infarction group is significant lower than that of thalamic hemorrhage group.How to prevent and manage medical complications are very important.For it can decrease the mortality and shortening the course of the thalamic stroke.(5)Most of the cases have favorable outcome.The prevention is most important for the thalamic stroke.Not only prevent the recurrences of thalamic stroke patients,but also the intervention therapy to the risk factors of the high risk group should be enhanced.
