彩色多普勒超声对乳腺肿物血管分布的研究

Research for distribution of blood vessels in breast neoplasms with color Doppler flow imaging

目的应用彩色多普勒超声探讨正常乳腺动脉对乳腺良、恶性肿物分支供血方式的差异。方法对248例经病理证实的乳腺肿物行彩色多普勒超声检查，扫查正常乳腺动脉与乳腺肿物的空间位置关系，比较分析它们对乳腺癌和乳腺良性肿物分支供血方式的差异。结果彩色多普勒超声显示穿人血管、穿入血管分支、直接血管分支及中央粗大血管是乳腺癌特征性血管分布形式，与乳腺良性肿物有明显差别。结论正常乳腺动脉对乳腺良、恶性肿物分支供血方式不同，借此可以鉴别两者。

Objective To explore the difference of normal breast artery feeding pattern between benign and malignant breast neoplasms with color Doppler flow imaging （CDFI）. Methods CDFI were performed for 248 cases breast neoplasms confirmed by pathology. Spatial location were observed between normal breast arteries and breast neoplasms. The difference of breast artery feeding pattern was compared between benign and malignant breast neoplasms. Results CDFI showed that penetrating vessels,branches of penetrating vessels, branches of direct vessels and central large vessels were characteristic breast cancer vascular distribution patterns, which were completely different from that of breast benign neoplasms. Conclusions The patterns of breast artery feeding breast cancer were different from that of breast benign neoplasms, that can identify both.
