动脉韧带钙化——生理性钙化

Ligamentum Arteriosum Calcification——Physiology Calcification

目的分析动脉韧带钙化（CLA）的多层螺旋CT表现及正确认识的意义。方法对1000例动脉韧带钙化患者的多层螺旋CT图像进行分析,按年龄分组,40岁以下每10岁为一组,分为4组,50~59岁为一组。比较各年龄组CLA的发生率及主动脉钙化情况。结果动脉韧带钙化总发生率为12.90%,各年龄组CLA发生率无统计学差异,仅30~39岁和50~59岁有统计学差异（P〈0.05）。结论动脉韧带钙化属于生理性钙化,无病理学意义,需正确区分动脉韧带钙化与主动脉钙化。

Objective To analyze the multi-slice spiral CT findings of calcification of the arterial ligament calcification（CLA） and think its meaning correctly. Method Multi-slice spiral CT findings of 1000 patients with CLA were analyzed retrospectively. These subjects were divided into five groups, under the age of 40 each for a group of 10 years were divided into four groups, a group of 50-59 years. To compare the incidence of CLA among all age groups and aortic calcification. Result Arterial ligament calcification total rate was 12.90%, the incidence of CLA had no statistical differences among all age groups, and only 30 to 39 years old and 50 to 59 years had statistically significant（P〈0.05）. Conclusion CLA is physiological calcification; it has no sense of pathology. Distinguishing between CLA and aortic calcification is very important.
