[目的]探讨高频超声在下肢软组织肿瘤中的诊断及指导治疗的应用价值。[方法]应用二维及多普勒超声显像对18例下肢软组织肿瘤进行检查,观察肿瘤大小、边缘情况、与周围组织的解剖关系以及内部回声、血流分布等,并进行术前导引下针吸活检,根据超声结果确定手术切除范围,与手术所见和病理结果进行对照分析,手术后进行高频超声复诊切除效果。[结果]18例肿瘤病理超声提示17例与手术、病理结果相符(17/18)。肿瘤切除后高频多普勒超声复诊显示1例血管瘤仍有少量血流信号,其余病例肿瘤切除彻底。[结论]高频超声可观察肿瘤的位置、性质、大小及与周围组织的解剖关系,彩色血流成像对提示肿瘤的良、恶性质有参考价值,并对肿瘤切除后效果及复发概率的评估有重要的指导意义。
[Objective] To explore the value of high-frequency ultrasound in the diagnosis and treatment of lower extremity soft tissue tumors. [Methods] 18 cases of lower extremity soft tissue tumors were examined by two-dimensional and Doppler ultrasonography. The tumor size, margins, anatomic relationship with the surrounding tissues, internal echo and blood flow distribution were observed and preoperatively guided Under needle biopsy, according to the results of ultrasound to determine the scope of surgical resection, surgical findings and pathological findings were analyzed, high-frequency ultrasound after resection resection results. [Results] Twenty-eight cases of tumor pathology showed 17 cases were consistent with the surgical and pathological findings (17/18). Radiofrequency Doppler sonography after tumor resection showed that there was still a small amount of blood flow signal in one hemangioma, and the remaining cases were completely resected. [Conclusion] The location, nature, size and the anatomic relationship with the surrounding tissues can be observed by high frequency ultrasound. Color flow imaging has reference value for the indication of benign and malignant tumors, and the evaluation of the effect of tumor resection and the recurrence probability Have important guiding significance.
