| ［摘要］ 目的 探讨血管壁回声跟踪技术（E-tracking技术，ET）检测阻塞性睡眠呼吸暂停低通气综合征（OSAHS）患者治疗前后颈总动脉血管弹性的变化。方法 选取30例OSAHS患者，采用高频线阵探头测量颈总动脉内中膜（IMT），应用ET技术实时跟踪描记治疗前和治疗3个月后的颈动脉管壁运动轨迹，检测出颈动脉的弹性系数(Eρ)、硬化参数(β)、顺应性(AC)、脉搏波传导速度(PWVβ)和增大指数(AI)。结果 OSAHS患者治疗后的颈总动脉较治疗前Eρ、β、PWVβ降低，AC升高（均P<0.01），AI降低（P>0.05）。结论 ET技术检测能明确OSAHS患者治疗前后的颈总动脉弹性变化，及早地发现血管病变，有效地指导OSAHS患者的临床治疗。 |

| ［Abstract］ Objective To analyze the changes of carotid artery elasticity in the patients with obstructive sleep apnea hypopnea syndrome(OSAHS) after the treatment with ET Technique.Methods Thirty patients with OSAHS were selected and given individualized treatment for three consecutive months. The intima-media thickness(IMT) was measured by high frequency linear ultrasound probe. An ultrasonic echo-tracking method was used to evaluate common carotid artery elastic modulus, including pressure-strain clastic modulus(Eρ), stiffness parameter(β), arterial compliance(AC), one point pulse wave velocity(PWVβ) and augment index(AI).Results After the treatment, Eρ,βand PWVβ decreased and AC increased compared with those after the treatment（P<0.01）. AI decreased to some extent after the treatment, but no difference was found before and after the treatment（P>0.05）.Conclusion ET can accurately detect the changes of carotid artery elasticity in the patients with obstructive sleep apnea hypopnea syndrome before and after the treatment. The changes of ET parameters can guide the clinical treatment of OSAHS and indicate atherosclerosis in an early stage. |
