摘要
目的：探讨应用二维高频超声及能量多普勒超声（PDI）技术评价不同病程2型糖尿病（T2DM）患者跟腱异常改变的临床应用价值。方法：收集60例T2DM患者，分为2组：病程≤10年（B组）30例；病程>10年（C组）30例。另选取30名健康志愿者为正常对照组（A组）。分别应用二维高频超声及PDI观察3组双下肢跟腱的回声及血流情况，测量3组双侧起点、中点、止点的厚度（D1）和宽度（D2）。结果：A组跟腱纵切面显示为连续均匀的细线样强回声；T2DM各组（B、C组）更易出现跟腱内回声减低、不均匀区或与腱旁组织分界不清等异常，B组、C组大于A组（P均<0.05）；跟腱内出现钙化灶比率C组大于A组（P<0.05）；出现腱旁组织异常的比率3组间无显著性差异。跟腱起点处，C组较A组的D1值增大（P<0.05）；中点处，B组、C组较A组，C组较B组的D1值增大（P均<0.05）；止点处，B组、C组较A组的D1值增大（P均<0.05）。3组跟腱内部1级血流信号最多，组间各级血流信号无显著差异。结论：二维高频超声和PDI能够客观评价不同病程T2DM患者跟腱的异常回声改变、增厚程度以及内部血流情况，具有重要的临床价值。
Abstract
Objective: To evaluate the value of two-dimensional high-frequency ultrasonography and power Doppler imaging(PDI) for judgement of the abnormalities of Achilles tendon in patients with type 2 diabetes mellitus(T2DM). Methods: A total of 60 patients of T2DM were enrolled and divided into two groups: group B(30 cases, the course≤10 years), group C(30 cases, the course>10 years). Thirty healthy subjects were enrolled in group A as normal control. The echotexture of Achilles tendon and blood flow were observed by two-dimensional high-frequency ultrasonography and PDI. The thickness(D1) and width(D2) of each tendon were measured at its starting point, middle point and insertion. Results: The ultrasound imaging of Achilles tendons in group A was shown string like homogeneous hyperechogenicity with clear border with surrounding tissue. The abnormal ultrasound findings, such as hypoechoic areas, heterogenous echogenicity, or indistinct border with surrounding tissue, were more frequently detected in group B and C than group A(all P<0.05). The ratio of calcification of group C was larger than that of group A(P<0.05). There were no significant difference in the ratios of abnormalities of the surrounding tissue among the groups of A, B and C(all P>0.05). At starting point, the thicknesses(D1) of group C were larger than group A(all P<0.05). At middle point, the thicknesses(D1) of group B and group C were larger than group A(all P<0.05), and the thicknesses(D1) of group C were larger than group B(all P<0.05). In the insertion, the thicknesses(D1) of group B and group C were larger than group A(all P<0.05). The blood flow of grade 1 was the most normal sign in the Achilles tendons in the groups of A, B and C. There were no significant difference among the groups of A, B and C in gradings of blood flow. Conclusions: To evaluate the abnormal echotextures, thickening and blood flow of Achilles tendons in the patients of T2DM by Two-dimensional high-frequency ultrasound and PDI are valuable for clinical.
