彩色多普勒超声检查对乳腺浸润性导管癌的诊断价值

The diagnostic value of color Doppler ultrasonography in breast infiltrating ductal carcinoma

目的探讨彩色多普勒超声检查对乳腺浸润性导管癌的诊断价值。方法回顾性分析55例经手术病理确诊为乳腺浸润性导管癌患者术前彩色多普勒超声诊断资料。结果55例乳腺肿块中，术前有彩色血流显示49例，元彩色血流显示6例。彩色血流显示诊断率与病理符合率为89．1％。乳腺浸润性导管癌超声图像特征：肿块呈不规则形，无包膜，后方回声衰减，有“毛刺征”、“蟹足状”等改变，肿块内多为不均匀性低回声，伴有微小簇状钙化或不规则光斑，后无声影，血流分布多表现为Alder Ⅱ～Ⅲ级，腋窝淋巴结不同程度肿大，淋巴门结构不清晰，收缩期峰值流速在12—80cm／s（平均35．1cm／s），阻力指数在0．62—0．92（平均为0．79±0．10）。结论彩色多普勒超声检查对乳腺浸润性导管癌早期诊断具有重要的价值。

Objective To explore the ultrasound images features of breast infiltrating ductal carcinoma. Methods Retrospective analysis of operation pathology,55 patients diagnosed preoperatively infiltrating ductal carcinoma of color Doppler ultrasound diagnostic information. Results Before operation, 55 patients with breast tumors had color Doppler shows in 49 cases, no color doppler showed 6 cases, color Doppler shows with pathologic diagnosis is 89. 1%. An infiltrating ductal carcinoma ultrasound image characteristics：the larger mass was irregular form, no coated,posterior acoustic attenuation,＂ burr levy＂, and ＂crabs foot shape＂ more inside, bump such change for not uniformity hypoechoic,with tiny dusters of calcified or irregular flare,shadow,blood flow distribution after silent for AlderⅡ- more performance level Ⅲ,axillary lymph node enlarge ment,a different level hilus structure was clear,the peak systolic ve- locity in 12-80cm/s （ average 35. 1 cm/s）, resistance index in 0. 62-0.92 （ average for 0. 79 ＋ 0. 10）. Conclusion Color doppler ultrasonography had important value in early diagnosis of infiltrating ductal carcinoma.
