【摘要】：目的对脑血管病易发年龄段健康人群的颈内动脉的管径和角度进行测量与分析,为临床提供重要的参考依据。方法选择191例无颈内动脉病变的50岁以上检查者的颅脑CT增强连续扫描动脉期数据集进行三维重建,测量颈内动脉角度和管径,并对结果进行统计学分析。结果颈内动脉各分段管径无明显的性别差异(P0.05)。颈内动脉各段管径结果显示：除C2与C4、C5与C6无显著性差异(P0.05)之外,其余各段均有显著性差异(F=39.037,P0.05)。颈内动脉相邻两段管径差结果显示：颈内动脉相邻两段管径差距中,海绵窦段与床突段之间差距(C4-C5)最大(F=28.193,P0.05)。角度测量中,男性颈内动脉中除虹吸弯与颈动脉管内曲、海绵窦段弯曲与颈动脉管内口弯曲、颈段上曲与颈段下曲角度之间差别不显著(P0.05)之外,其余各角度之间均有显著性差别(F=30.168,P0.05)；女性颈内动脉角度结果显示：海绵窦段弯曲与颈动脉管内口弯曲、颈段上曲与颈段下曲角度之间差别不显著(P0.05)之外,其余各角度之间均有显著性差别(F=30.168,P0.05)。结论颈内动脉在走行过程中管径逐渐变细,其中破裂孔段与海绵窦段之间变化最大,颈内动脉走行各角度中虹吸弯角度最小,提示该部位为脑动脉粥样硬化的好发部位。
[Abstract]:Objective to measure and analyze the diameter and angle of the internal carotid artery in the healthy population of cerebrovascular disease prone age, and to provide an important reference for clinical practice. Methods Intra-carotid artery angle and diameter were measured in 191 patients over 50 years of age without internal carotid artery disease, and the results were analyzed statistically. Results there was no significant gender difference in the diameter of the internal carotid artery (P0.05). The diameter of internal carotid artery showed no significant difference except C2 and C4C5 and C6 (P0.05). The results showed that the difference between cavernous sinus segment and clinoid process segment (C4-C5) was the largest (F28.193 P 0.05) in the two adjacent segments of the internal carotid artery. In angle measurement, the male internal carotid artery had no significant difference except siphon curvature and carotid canal curvature, cavernous sinus segment bending and carotid artery internal orifice bending, and superior cervical curvature and inferior cervical curvature angle (P0.05). There were significant differences between the other angles (FF30. 168); The results of angle of female internal carotid artery showed that there was no significant difference between cavernous sinus segment bending and carotid artery internal orifice bending, and there was no significant difference between superior cervical segment curvature and inferior cervical segment angle (P0.05), but there were significant differences among other angles (F _ (30.168), P _ (0.05), P < 0.05). P0.05). Conclusion the diameter of the internal carotid artery gradually becomes thinner during the course of the internal carotid artery, and the siphon angle of the internal carotid artery is the least among all the angles of the internal carotid artery walking, which indicates that the internal carotid artery is the predilection site of atherosclerosis.
