【摘要】 目的:研究高频超声在跟腱断裂修复术后患者的临床监测应用价值。方法:应用GE E9超声诊断仪,探头频率9~15 MHz,肌肉骨骼预设条件,受检者分别于手术后4周、6周、12周、24周行高频超声检查,记录相关数据,并做患侧与健侧比较。结果:38例跟腱断裂修复术后患者,患侧与健侧比较探查:4周时患侧跟腱内部回声紊乱减低,厚度明显增厚,缝合端显示短线状或点线状彩色血流;6周时患侧跟腱内呈中低回声,内可显示部分跟腱连续信号,内部仍有血流信号;12周时患侧跟腱内部回声增强,厚度较前减小,跟腱连续性较完整,内部血流信号明显减少;24周时患侧跟腱与健侧回声类似,内纹理清晰,内部血流信号基本消失。患侧跟腱缝合端最宽处厚度和横断面积有逐渐减小的趋势,但相对健侧仍较大,双侧比较具有统计学意义。结论:1.跟腱断裂修复术后4周、6周、12周、24周声像图存在差异性,其厚度、面积双侧比较具有统计学意义,患侧跟腱内血流信号随时间延长逐渐减少。2.高频超声可用于监测、跟踪随访跟腱断裂修复术后患者跟腱声像图变化,并以此指导患者康复。更多还原

【Abstract】 Objective: To study the value of high frequency ultrasound in the clinical monitoring of patients undergoing the repair surgery of ruptured Achilles tendon.Methods: GE E9 ultrasonic diagnostic apparatus with a probe at a frequency of 9-15 MHz was employed in this study.The conditions of muscles and skeletons were pre-set,and subjects underwent high-frequency ultrasonography before and 4,6,12,24 weeks after surgery.The data were recorded and the affected side and the healthy side were compared.Results: The comparison between the affected side and the healthy side in 38 patients undergoing the repair of ruptured Achilles tendon showed that echo in Achilles tendon at the affected side was disordered and decreased,the thickness significantly decreased,and the suture end showed short linear or spotted-linear color flow signals at the 4th week;moderate and low echoes were detected in Achilles tendon at the affected side,and partial continuous signals of Achilles tendon and blood flow signals were seen at the 6th week.Echo in Achilles tendon at the affected side was enhanced,the thickness decreased,the Achilles tendon was continuous and complete,and internal blood flow signals decreased significantly at the 12 th week;the echo of Achilles tendon at the affected side was similar to that at health side,with clear textures,and internal blood flow signals almost disappeared at the 24 th week.The widest cross-sectional thickness and area at the suture end decreased gradually,but was still larger than that at the healthy side,comparison between the two sides being statistically significant.Conclusions: 1.The Images of repaired Achilles tendon at the 4th,6th,12 th and 24 th week after the surgery differed,and the difference in the thickness and the area at both sides are statistically significant.The blood flow signals of the Achilles tendon at the affected side decreases over time.2.High frequency ultrasound can be used to monitor and follow up the rehabilitation process of ruptured Achilles tendon,and the difference of images also has guidingsignificance for the rehabilitation.更多还原
