老年人颈内动脉虹吸部钙化积分与腔隙性脑梗死的 　　【摘要】 目的：探讨老年人颈内动脉虹吸部钙化积分与前循环脑梗死的关系。方法：随机抽取271例老年人头颅CT片，计算颈内动脉虹吸部钙化积分，并同时观察腔隙性脑梗死的发生情况。结果：271例患者中，217例发现虹吸部钙化，其中总钙化分数为1～199分有83例，46例为腔隙性脑梗死；总钙化分数为200～399分有98例，65例为腔隙性脑梗死；总钙化分数为400～500分36例，33例为腔隙性脑梗死；另有54例未发现虹吸部钙化，11例为腔隙性脑梗死。经卡方检验，除外总钙化分数400～500分组，其余各钙化积分组组缺血性脑病发生率比较差异有统计学意义（P0.05）。结论：颈内动脉虹吸部钙化积分越大，腔隙性脑梗死的发生率越大。钙化作为颈内动脉粥样硬化的晚期征象，是提示潜在的缺血性脑卒中的可靠依据。 　　【关键词】 颈内动脉； 虹吸部； 钙化积分； 腔隙性脑梗死； 动脉粥样硬化 　　中图分类号 R256 文献标识码 A 文章编号 1674-6805（2014）13-0001-02 　　Association between Calcification Score at Siphon Segment of Internal Carotid Artery and Lacunar Infarction in Anterior Circulation/ZHANG Jun-yuan，LI Li-xin.//Chinese and Foreign Medical Research，2014，12（13）：1-2 　　【Abstract】 Objective：To assess the relationship of calcification score at siphon segment in internal carotid artery with lacunar infarction in the anterior circulation.Method：The cranial CT imaging of 271 cases of aged were reviewed at random.Calcification score at siphon segment in internal carotid artery was calculated using agatston’s method，at the same time，the probability of lacunar infarction in the anterior circulation was observed. Result：Calcification at the siphon segment in internal carotid arteries had been found in 217 cases.Lacunar infarction was found in 46 cases of 83 cases which calcification score was from 1 to 199 scores ，in 65 cases of 98 cases which calcification score was from 200 to 399 scores ，and in 33 cases of 36 cases which calcification score was from 400 to 500 scores .Lacunar infarction occurred in 11 of 54 cases without calcification.Statistical analysis showed that calcification score was significantly associated with lacunar infarction（P0.05）.Conclusion：With the growth of calcification score at the siphon segment in internal carotid arteries，the probability of lacunar infarction has increased.Though calcification is a late sign of atherosclerosis of internal carotid arteries，it may suggest the possibility of potential ischemic cerebrovascular disorders.
