目的:探讨乳腺占位性病变患者应用B超诊断的效果及临床价值研究,为乳腺占位性病变的诊断提供依据。方法:选取嘉兴市妇幼保健医院2013年6月-2015年1月收治的76例乳腺占位性疾病患者进行研究,所有患者均经病理证实其占位性,并对良恶性乳腺占位性病变的超声声像图及腋窝淋巴结转移、血流分级情况进行比较。结果:76例患者中诊断乳腺占位性病变的有71例,其中乳腺增生24例、乳腺纤维瘤20例、乳腺囊肿12例、乳腺硬癌8例、乳腺乳头状导管癌5例、乳腺髓样癌2例;76例患者术前超声检查71例患有占位性病变,与病理诊断相比,其阳性率为93.42%;超声检查可见,良性肿瘤淋巴结转移率较低,而恶性肿瘤转移率达100%;且恶性肿瘤平均血流分级显著高于良性肿瘤,差异有统计学意义。结论:超声检查可以作为乳腺占位性病变诊断的常用手段之一,值得广泛推广和应用。 Objective: To investigate the effect and clinical value of B-ultrasound in patients with breast mass lesions to provide basis for the diagnosis of breast lesions. Methods: A total of 76 patients with breast-space-occupying diseases who were treated in Jiaxing Maternal and Child Health Hospital from June 2013 to January 2015 were enrolled in this study. All patients were confirmed by pathology for their occupancy and benign and malignant breast lesions Ultrasound sonography and axillary lymph node metastasis, blood flow classification were compared. Results: Of the 76 patients, 71 cases were diagnosed as breast lesions, including 24 cases of breast hyperplasia, 20 cases of breast fibroids, 12 cases of breast cysts, 8 cases of breast cancer, 5 cases of papillary ductal carcinoma, Like cancer in 2 cases; 76 patients preoperative ultrasound examination of 71 patients with lesions, compared with the pathological diagnosis, the positive rate was 93.42%; ultrasound examination shows benign tumor lymph node metastasis rate is low, and malignant tumor metastasis Rate of 100%; and the average grade of malignant tumors was significantly higher than benign tumors, the difference was statistically significant. Conclusion: Ultrasound can be used as a common diagnostic tool for breast lesions, it is worth widely extended and applied.
