摘要: 目的  基于高帧率剪切波(high frame rate sound touch elastography,HiFR STE)评价血液透析患者冈上肌腱的力学性能。方法  选取汕头大学医学院第一附属医院规律血液透析的患者46例和健康志愿者23例。通过透析龄中位数(74.5个月)将血液透析患者分为透析龄较短组[49.00(14.00, 69.00)]和透析龄较长组[91.00(78.00,122.00)]。使用迈瑞Resona R9 Pro超声诊断仪及L15-3Wu线阵探头进行二维超声和HiFR STE成像,测量并比较不同透析龄的血液透析患者和健康对照组的冈上肌腱厚度及杨氏模量平均值(the mean of Young's modulus,Emean)的差异,并观察各组间肩关节的骨质破坏、滑膜增厚及关节积液常规声像特征。结果  健康对照组、透析龄较短组及透析龄较长组的冈上肌腱厚度和Emean值在3组间差异有统计学意义(P<0.001),冈上肌腱厚度分别为(5.73±0.70)mm、(6.57±0.93)mm和(6.80±0.84)mm,两两比较结果显示不同透析龄的血液透析患者冈上肌腱厚度均高于对照组(P<0.05);HiFR STE测得3组的冈上肌腱Emean值分别为(61.27±21.64)kPa、(42.56±25.30)kPa和(31.13±17.40)kPa,两两比较结果显示不同透析龄的血液透析患者冈上肌腱Emean值均低于对照组(P<0.05);骨侵蚀率及滑膜增厚率在3组间的差异具有统计学意义(P<0.05)。结论  血液透析患者的冈上肌腱增厚及出现力学性能下降。基于HiFR STE技术测得的Emean对血液透析患者冈上肌腱的力学性能进行定量评估,可为临床筛选肩袖撕裂的潜在风险人群提供客观依据。

Abstract: Objective  To evaluate the mechanical properties of supraspinatus tendons in hemodialysis patients with high frame rate sound touch elastography (HiFR STE). Methods  Forty-six patients who routinely underwent hemodialysis at the First Affiliated Hospital of Shantou University Medical College, as well as twenty three fit volunteers, were selected for the study. Patients on hemodialysis were divided into two groups based on their median dialysis duration (74.5 months): the shorter dialysis duration group and the prolonged dialysis duration group [49.00(14.00, 69.00) vs 91.00(78.00, 122.00)]. Two-dimensional ultrasound and HiFR STE imaging were performed using a Mindray Resona R9 Pro ultrasound diagnostic instrument and an L15-3Wu line array probe. The supraspinatus tendon thickness and the mean of Young's modulus (Emean)were measured and compared between hemodialysis patients with varying durations of dialysis and healthy controls. Additionally, the sonographic characteristics of the shoulder joint were observed, including bone destruction, synovial hypertrophy, and joint effusion.  Results  The differences in supraspinatus tendon thickness and Emean values among healthy control group, shorter dialysis age group and longer dialysis age group were statistically significant(P<0.001), with the supraspinatus tendon thickness (5.73±0.70)mm, (6.57±0.93)mm and (6.80±0.84)mm, respectively. The result of two-by-two comparisons showed that the supraspinatus tendons thickness were thicker in both groups of hemodialysis patients with differing dialysis durations than in controls(P<0.05). HiFR STE results showed that their Emean values was (61.27±21.64)kPa、(42.56±25.30)kPa and (31.13±17.40)kPa, respectively. The result of two-by-two comparisons showed that the Emean value of supraspinatus tendons was significantly lower in dialysis patients than in controls, and the incidence of bone erosion and synovial thickening were statistically significant among the three groups(P<0.05). Conclusion  Supraspinatus tendons in hemodialysis patients thickened and showed decreased mechanical properties. Quantitative evaluation of supraspinatus tendon elasticity in hemodialysis patients based on the Emean measured by the HiFR STE can provide objective evidence for clinical screening of potential group of rotator cuff tears.
