摘　　要：目的:探讨瘢痕疙瘩剪切波弹性成像(SWE)与改良瘢痕量表(MSS)评分的相关性。方法:选取瘢痕疙瘩患者47例(共52个病灶),先运用二维超声评估病灶大小、内部回声、累及层次,再用CDFI观察病灶血流情况,对病灶行SWE,测量其横向、纵向及邻近皮肤的平均杨氏模量值。同时用MSS对病灶进行评估,评价MSS评分与杨氏模量值的相关性。结果:瘢痕疙瘩横向与纵向平均杨氏模量值差异有统计学意义(Z=-5.086,P<0.01),横向与邻近皮肤平均杨氏模量值差异有统计学意义(Z=-5.086,P<0.01),纵向与邻近皮肤杨氏模量值差异无统计学意义(Z=-0.316,P=0.752)。瘢痕疙瘩横向平均杨氏模量值与临床MSS评分密切相关(r_(s)=0.635,P<0.001),纵向平均杨氏模量值与临床MSS评分无相关性(r_(s)=0.08,P=0.652)。结论:瘢痕疙瘩横向平均杨氏模量值与MSS评分呈正相关;SWE可客观评估瘢痕疙瘩的组织硬度,为瘢痕疙瘩的诊断、疗效评估等提供依据。Objective:To explore the correlation between shear wave elastography(SWE)and the modified scar scale(MSS)score in keloids.Methods:A total of 52 sites in 47 patients with keloids were selected,and ultrasound was used to evaluate the size,internal echoes,involved tissue and CDFI was used to observe the blood flow of the lesion.SWE was used to evaluate the average Young’s modulus the lateral,longitudinal and adjacent skin of the lesion.At the same time,MSS was used to evaluate the lesions,and the correlation of MSS score and Young’s modulus was evaluated.Results:There was a statistically significant difference between the transverse average Young’s modulus and the longitudinal average Young’s modulus of keloids(Z=-5.086,P<0.01)and between the transverse average Young’s modulus and the average Young’s modulus of the skin adjacent to the lesion(Z=-5.086,P<0.01).There was no statistically significant difference between the longitudinal average Young’s modulus and the Young’s modulus of the skin adjacent to the lesion(Z=-0.316,P=0.752).The transverse average Young’s modulus of keloids was closely related to the MSS score(r_(s)=0.635,P<0.001),but the longitudinal average Young’s modulus and MSS score were not related(r_(s)=0.08,P=0.652).Conclusions:The transverse average Young’s modulus of keloids is positively correlated with the MSS score.It can objectively evaluate the tissue hardness of keloids and provide a basis for the diagnosis and curative effect of keloids.
