摘要
目的 探讨高频超声检查在小儿先天性巨趾(指)术前诊断及神经受累评估中的应用价值.方法 选取 8 例经手术及病理证实先天性巨趾(指)畸形患儿临床及超声检查资料,与病理结果进行对比分析,总结小儿先天性巨趾(指)声像图特点及神经受累情况.结果 先天性巨趾 5 例(右:左=3:2),先天性巨指 3 例(右:左=1:2).共 15 趾、6 指,趾别发病率:第 2 趾>第 3 趾>第 4 趾>拇趾=第 5 趾;指别发病率:拇指=示指>中指=小指.超声表现为患趾/指皮下软组织不同程度增厚,受累神经均增粗、回声增强,受累段神经束膜模糊.结论 高频超声检查软组织分辨率高,能清楚显示四肢甚至末端的皮肤、皮下软组织及神经.术前行高频超声检查可为临床提供神经受累范围,提高手术效果、避免二次手术,具有重要的临床价值.
Abstract
Objective To investigate the application value of high frequency ultrasonography in preoperative diagnosis and evaluation of nerve involvement in children with megadactyly.Methods The clinical and ultrasonic examination data of 8 chil-dren with congenital megadactyly/finger deformity confirmed by surgery and pathology were collected and compared with the pathological results to summarize the sonographic characteristics and nerve involvement of children with congenital megadactyly/finger deformity.Results There were 5 cases of congenital megadactyly(right:left =3:2),and 3 cases of congenital megadac-tyly(right:left =1:2).There were 15 toes and 6 fingers in total,and the toe specific incidence rate was as follows:the second toe>the third toe>the fourth toe>the big toe = the fifth toe;Finger incidence rate was as follows:thumb = index finger>middle finger = little finger.Ultrasound showed that the subcutaneous soft tissue of the affected toe/finger was thickened to varying degrees,the affected nerves were thickened,the echo was enhanced,and the nerve fascicular membrane of the affected segment was blurred.ConclusionHigh frequency ultrasound has high resolution in soft tissue,and can clearly show the skin,subcutaneous soft tissue and nerves of limbs and even the ends.Preoperative high-frequency ultrasound examination can pro-vide the clinical range of nerve involvement,improve the surgical effect and avoid secondary surgery,which has important clinical value.
