【摘要】：目的探讨视网膜分支静脉阻塞与颈内动脉狭窄及颈内动脉弹性功能参数的相关性。方法选择2014年1月至2014年11月在首都医科大学附属北京友谊医院眼科确诊为视网膜分支静脉阻塞病人56例(56眼)作为研究组,对照组选取无视网膜分支静脉阻塞者36例(36眼),均进行多普勒彩超检查,测定颈内动脉的收缩期内径(systolic diameter,Ds)、舒张期内径(diastolic diameter,Dd)、收缩期血流峰值(peak systolic velocity,Vs)、舒张期血流峰值(end diastolic velocity,Vd)、平均血流速度(mean velocity,Vm)、内-中膜厚度(intima-media thickness,IMT)、斑块形成情况,计算颈内动脉弹性功能参数:管壁运动度(wall motion degree,ΔD)、动脉紧张度、扩张性、压力-应变性系数(pressure-strain elastic modulus,Eρ)、僵硬度指数(stiffness index,β)、顺应性(arterial compliance,AC)、阻力指数(resistance index,RI),将2组各指标进行比较分析。结果颈动脉斑块、颈内动脉狭窄发生比例及颈内动脉的IMT等指标,研究组明显高于对照组(P0.05)。颈内动脉管壁运动度(ΔD)、动脉紧张度、动脉扩张性、压力-应变性系数(Eρ)及顺应性(AC)等指标,研究组与对照组比较,差异具有统计学意义(P0.05)。研究组的平均血流速度(Vm)、阻力指数(RI)及僵硬度指数(β)与对照组比较,差异无统计学意义(P0.05)。结论视网膜分支静脉阻塞的发生与颈内动脉狭窄及颈内动脉弹性功能参数的改变有一定的相关性。
[Abstract]:Objective to investigate the correlation between retinal branch vein occlusion and internal carotid artery stenosis and elastic function of internal carotid artery. Methods from January 2014 to November 2014, 56 eyes of 56 patients diagnosed as retinal branch vein occlusion in Beijing Friendship Hospital affiliated to Capital Medical University were selected as the study group. In the control group, 36 patients (36 eyes) without retinal branch vein occlusion were examined by color Doppler ultrasonography. The systolic diameters of the internal carotid artery, diastolic diameterus, peak systolic velocityVSD, end diastolic velocityVdn, mean velocity Vmand, intima-media thicknessen, plaque formation were measured. The elastic function parameters of internal carotid artery were calculated as follows: wall motion degree, 螖 D, arterial tension, expansibility, pressure-strain elastic modulus E 蟻, stiffness index, compliance index and resistance index, resistance index index. Results carotid plaque, internal carotid artery stenosis and IMT of the internal carotid artery were significantly higher in the study group than in the control group (P 0.05). The indexes of internal carotid artery wall motion (螖 D, arterial tension, arterial dilatation, pressure-to-anisotropy coefficient E 蟻) and compliance with acid were significantly higher in the study group than in the control group (P 0.05). The mean blood flow velocity, resistance index (RI) and stiffness index (尾) of the study group were not significantly different from those of the control group (P 0.05). Conclusion the occurrence of retinal branch vein occlusion is related to the stenosis of internal carotid artery and the change of elastic function parameter of internal carotid artery.
