BACKGROUND
We aimed to compare the frequency of IMA (internal mammarian artery) anastomoses in right and left breasts in patients without breast lesions and in patients with malignant breast lesions.
MATERIAL/METHODS: A total of 100 patients with no breast lesions and a total of 100 patients with malignant breast lesions were included in the study. The anastomoses of IMA of right and left breasts were evaluated on MIP and post-contrast T1-weighted magnetic resonance imaging (MRI) sequences. Breast MRI scans were read by a radiologist.
RESULTS
In patients with no breast lesions, IMA anastomoses were found in 45% of cases, and in patients with malignant breast lesions, IMA anastomoses were found in 58% cases. In four patients with malignant lesions, ipsilateral IMA was rudimentary, and the lesion was feeding from the contralateral IMA.
CONCLUSIONS
No statistically significant difference was found between patients without any breast lesions and patients with malignant breast lesions with respect to the frequency of IMA anastomoses in right and left breasts. The frequencies were higher than expected in both groups.
背景
我们旨在比较无乳腺病变患者和乳腺恶性病变患者左右乳房内乳动脉（IMA）吻合的频率。
材料/方法：本研究共纳入100例无乳腺病变患者和100例乳腺恶性病变患者。在最大密度投影（MIP）和对比剂增强后的T1加权磁共振成像（MRI）序列上评估左右乳房IMA的吻合情况。乳腺MRI扫描由一名放射科医生解读。
结果
在无乳腺病变的患者中，45%的病例发现有IMA吻合；在乳腺恶性病变患者中，58%的病例发现有IMA吻合。在4例恶性病变患者中，同侧IMA发育不全，病变由对侧IMA供血。
结论
在左右乳房IMA吻合频率方面，无任何乳腺病变的患者与乳腺恶性病变患者之间未发现统计学上的显著差异。两组的频率均高于预期。
