摘要
目的应用彩色多普勒超声技术,测定乳腺供血动脉进行血流动力学参数,探讨乳腺供血动脉血流参数在乳腺增生症中的差异,拟提供乳腺增生病的彩超诊断依据。方法收集绝经前汉族成年女性105例,病理证实乳腺增生症者75例,根据声像图表现分为四种类型,即低回声区型、囊肿形成型、实质性肿块型、混合型。健康对照组选用绝经前成年汉族非哺乳期健康女性30例。资料完整。分析各组血流参数的特征。分析乳房供血动脉血流动力学参数与肿块数目、肿块大小、肿块内血流丰富程度的相关性。结果 (1)乳腺增生症中混合型的各乳腺供血动脉内径明显低于其他三型和健康对照组,差异有统计学意义(P<0.05)。(2)乳腺增生症中囊肿形成型的胸肩峰动脉的S/D值明显高于其他三型及健康对照组,差异有统计学意义(P<0.05)。(3)实质性肿块型的胸外侧动脉、胸肩峰动脉明显高于健康对照组;实质性肿块型的胸廓内动脉第2肋间穿支RI值明显低于健康对照组,差异有统计学意义(P<0.05)。(4)乳腺增生组胸外侧动脉血流参数(S/D、PI、RI)与肿块大小呈负相关,与肿块数目、发生象限、血流分级无明显无相关性。结论彩色多普勒超声显示乳腺增生症不同分型供血动脉的内径变化、S/D值和RI值升高。胸外侧动脉血流参数与肿块大小呈负相关。
Objective To study the manifestation of the Color Doppler and himodyna mics of the main breast- feeding arteries with color doppler flow imaging （CDFI）,probe into the doppler indices difference of the main breast- feeding arteries in the cYclomastopathy.Provide the objective basis of iconography for the diagnosis of cyclomastopathy. Methods Gathering the premenopausal Han adult females in 105 cases.75 patients cyclomastopathy,they were identified by pathologic diagnosis.According to the image of high frequency ultrasonography,they were divided into four types, They were low echo-level plaques, ductal ectasia and cystic space - occupying lesions,substantlal mass showed nodules and lumps with reduces echo-level,mixed mass which it include cystic and solid lesions or ductal estaia.Thirty women volunteers with Premenopausal no breast disease adult Han non-lactating women were served as controls. In this study they were recruited in one week before surgery by color doppler ultrasound.Analysis of the feature of the blood flow parameters respectively.Analysis of the correlation in LTA the blood flow parameters and tumor number, size, blood flow within respectively. Results （1）The mixed mass type in cyclomastopathy,the mean diameter of the breast-feeding arteries were significantly lower than low echo-level plaques type,substantial mass type, cystic space type and the contral groups.The difference was statistically significant（P 〈 0.05）.（2）The S/D ratios of the TA in the cystic space type of cyclomastopathy,which they were significantly higher than low echo-level plaques type, mixed mass type,substantial mass type and the contral groups,The difference was statistically significant （P 〈 0.05）.（3）In substantial mass type of cyclomastopathy groups,the RI ratios of the LTA and TA were significantly higher than the contral groups.In substantial mass type of cyclomastopathy groups,the mean RI of the ITA 2nd intercostal perforator were significantly lower than the healthy lateral.The difference was statistically significant（P 〈 0.05）.（4）In patient with cyclomastopathy, blood flow parameters of LTA were negatively correlated with tumor size,and no correlated with the degree of blood flow, tumor number, tumor position. Conclusion Color doppler flow image of breast-feeding arteries in cyclomastopathy showed arteries diameter changes, the S/D and RI value increased, S/D ratios,PI,and RI of LTA were correlated with tumor size.
