Color Doppler ultrasonography in evaluating arterial hemodynamics of hands in patients with Raynaud's phenomenon / 中国介入影像与治疗学

ABSTRACT

Objective To evaluate the value of the color Doppler ultrasonography in assessing the changes of the superficial palmar arch arteries and the proper palmar digital arteries in patients with Raynaud's phenomenon.Methods The color Doppler ultrasonography was used to check the left superficial palmar arch arteries and the left middle finger proper palmar digital arteries in 42 patients with Raynaud's phenomenon (case group).The blood vessel flow,blood flow filling and hemodynamic parameters were recorded.The hemodynamic parameters include peak systolic velocity (PSV),end diastolic velocity (EDV),resistance index (RI) and pulsatility index (PI).The control group was 35 healthy adults who received physical examination.The above parameters were measured,and the difference of the parameters between the case group and the control group were compared.Results The blood flow signal dispayed rate of the left superficial palmar arch arteries of case group was good,almost 100％ (42/42);the blood flow of the middle finger proper palmar digital arteries was poor,the blood vessel was thinner and even occluded,the blood flow signal displayed rate was 92.86％ (39/42).Compared with the control group,the PSV and EDV of the left middle finger proper palmar digital arteries decreased,the EDV of the superficial palmar arch arteries decreased also,but the RI and PI increased in case group (all P＜0.05),The PSV of the left superficial palmar arch arteries of the case group was lower than that of the control group,and there was no significant difference between both groups (P＞0.05).Conclusion The color Doppler ultrasonography can evaluate the hemodynamic changes of the proper palmar digital arteries and the superficial palmar arch arteries in patients with Raynaud's phenomenon,and provide effective evidence for the diagnosis and treatment of Raynaud's phenomenon.
