Abstract:
ObjectiveTo explore the hemodynamic characteristics of parotid glands before and after acid stimulation test in patients with Sjogren syndrome.MethodsTwenty female patients with Sjogren syndrome were enrolled as case group,and 20 healthy women were selected in the same period as control group.The blood flow spectrums of bilateral superficial temporal artery and intra-parotid small artery before and after acid stimulation were detected by color Doppler ultrasonography.Peak systolic velocity (PSV),end-diastolic minimum velocity(EDV) and resistance index( RI ) were obtained and analyzed.ResultsPSV and EDV of intra-parotid small artery in case group were significantly higher than those in control group before acid stimulation test,and RI was obviously lower than that in control group [ ( 16.01 ± 6.18 ) cm/s vs.( 14.00 ± 5.23 ) cm/s,( 5.96 ± 3.00 ) cm/s vs.( 3.54 ± 2.03 ) cm/s,0.64 ± 0.07 vs.0.76 ± 0.06 ] ( P ＜ 0.05 ).In control group,PSV and EDV of superficial temporal artery and intra-parotid small artery increased and RI reduced after acid stimulation test,which had significant differences before and after acid stimulation test (P ＜ 0.05).There was no statistical significance in the hemodynamic indexes of case group before and after acid stimulation test(P＞ 0.05 ).Conclusions The reactivity of parotid artery to acid stimulation test in patients with Sjogren syndrome reduce,especially the intra-parotid small artery.Color Doppler ultrasonography can contribute to show the hemodynamic changes of the parotid lesions efficiently.
