【摘要】 目的:比较正常对照组与雷诺现象(RP)患者组手掌指动脉的血流动力学差异,为 RP 的诊断提供血流动力学的客观指标。方法:用彩色多普勒起声对26例正常对照(均为左手)及16例 RP 患者(左手13只,右手9只)的食指尺掌侧固有动脉 (UPPDA)及桡侧掌深弓动脉(DRA)的血流动力学进行检查,测量指标:收缩期峰值流速(SPV),舒张末期流速 (EDV)、阻力指数(RI),搏动指数(PI),从正常对照组及病例组中各选取5例对左手 UPPDA 及 DRA 进行重复测量, 测量指标同前,每隔5分钟测量一次,共测量三次。结果:血流动力学指标测量的重复性可以接受(研究变异<30%,可区分级数>5).正常对照组 UPPDA 与 DRA 的 SPV 无统计学差异,UPPDA 的 EDV 高于 DRA,RI、PI 低于 DRA,差异有统计学意义.RP 患者组 UPPDA 与 DRA 血流动力学指标无统计学差异,RP 患者组的 UPPDA 与 DRAA 流速度低于正常对照组,UPPDA 的 RI、PI 高于正常对照组,差异有统计学意义。结论:正常对照组与 RP 患者组手掌指动脉的血流动力学存在显著性差异,彩色多普勒超声可以为 RP 的诊断提供血流动力学的客观指标。更多还原

【Abstract】 purpose The purpose of this study was to compare the hemodynamics of arteries of the hand in patients with Raynaud’s phenornenon(RP)and in healthy subjects,and to provide objective standards of hernodynamics for diagnosis of RP. Metheds Color Doppler ultrasonography was applied to 26 healthy subject(26 left hands)and 16 patients with RP(13 left hands and 9 right hands).The hemodynamics of the ulnar proper palmer digital artery(UPPDA)of index finger and the deep radial arch(DRA)were examined.The peak systolic velocity(SPV),end-diastolic velocity(EDV),resistive index(RI) and pulsatility index(PI)were determined.The hemodynamic indicators of left UPPDA and DRA of 5 healthy subjects and 5 patients with RP were measured three times,every 5 minutes once,and the repeatability was analyzed. Results The study variation and the number of distinct categories of the repeated measurements reflected an acceptable repeatability.There were no significant differences in SPV of UPPDA and DRA in control group.EDV of UPPDA in control group was significantly higher,but RI、PI were significantly lower than those of DRA.There were no significant differences in hemodynamic indicators of UPPDA and DRA in RP group.The blood velocities of DRA and UPPDA in RP group were lower than those in control group,but RI and PI of UPPDA were higher than those in control group. Conclusion The hemodynamics of UPPDA and DRA in the two groups were significantly different.Color Doppler ultrasonography could provide objective standards of hemodynamics for diagnosis of RP.更多还原
