摘要 目的应用多排螺旋CT血管造影(MDCTA)测量健康老年人颈动脉,观察老年人颈动脉结构和功能改变的特点。方法从颈部动脉MDCTA检查正常的健康成人中随机选择老年组(≥60岁)和非老年组(<60岁者)各60例(两组男、女分别为30例)进行回顾性分析,将薄层血管扫描数据传至影像工作站进行血管成像,利用血管测量软件分别测量颈总动脉(CCA)、颈内动脉颅外段(E-ICA)、颈内动脉海绵窦段(ICA-C4)和床突上段(ICA-C2),比较两个年龄组间血管直径的差异。结果老年人颈动脉直径无明显的性别差异。CCA和ICA-C4段直径左右侧略有差异(P<0.05)。仅CCA直径年龄组间差异有统计学意义(P<0.001)。结论年龄增长的生理性作用对颈总动脉直径扩大具有重要影响,但并非颈动脉各段血管直径改变的必然因素。老年人颈动脉直径在性别和侧别之间的差异无重要的临床意义。
