【摘要】：目的:探索高原地区患者颅脑CT平扫显示血管密度增高的病因,分析其与血红蛋白浓度的相关性。方法:搜集居住在海拔2500~4800m的186例颅内血管密度增高患者的病例资料作为研究组,另选取98例颅脑CT正常的成人为对照组。分析所有患者临床特点,统计各种病因所占比例,比较两组颅内动脉、静脉窦CT值、近期血红蛋白含量的差异并进行统计学分析。结果:186例高原地区颅内血管CT值增高患者中,慢性阻塞性肺病(COPD)134例,占72.0%,慢性高原病(CMS)46例,占24.7%,右向左分流型先天性心脏病(CHD)6例,占3.2%。与对照组相比,研究组血红蛋白含量、脑动脉、静脉窦CT值均增高,差异具有统计学意义(F=720.781、150.952、221.988,P0.01)。颅内血管密度增高组脑动脉CT值与血红蛋白含量呈正相关(b=0.202、0.271、0.292,P0.05)。结论:高原地区颅内血管密度增高及程度与血红蛋白含量呈正相关,高原地区引起血红蛋白浓度增高的病变都可能使脑血管密度增高。
[Abstract]:Objective: to explore the etiology of increased vascular density on plain CT scan in patients with high altitude and to analyze its correlation with hemoglobin concentration. Methods: 186 patients with increased intracranial vascular density living at 2500m and 4800m above sea level were collected as study group and 98 normal adults as control group. The clinical characteristics of all the patients were analyzed and the proportion of various etiological factors were counted. The difference of CT value of intracranial artery and venous sinus and the recent hemoglobin content between the two groups were compared and statistically analyzed. Results among 186 patients with elevated CT value of intracranial vessels in high altitude, 134 cases (72.0%) were chronic obstructive pulmonary disease (COPD), 46 cases (24.7%) were CMSD and 6 cases (3.2%) were right to left shunt congenital heart disease. Compared with the control group, the content of hemoglobin, the CT value of cerebral artery and venous sinus in the study group were higher than those in the control group, and the difference was statistically significant (P 0.01). There was a positive correlation between the CT value of cerebral artery and the content of hemoglobin in the group with increased intracranial vascular density. Conclusion: there is a positive correlation between the increase of intracranial vascular density and the content of hemoglobin in high altitude area.
