Detection of he relationship between internal mammary artery bypass graft resistive index and breastfeedng

Internal mammary artery is very important for coronary artey bypass surgery as a graft . We aim to determine the differences between breastfeeding and not-breastfeeding women's internal mammary artery resistive index using color doppler ultrasonography. In our study, 82 women whom refer to Şifa University Training and Research Hospital ; ages range between 23 -43 and agree to participate in the study were placed . Detailed history was taken and physical examination was performed . 16 volunteers excluded from the study couse of various reasons. 66 women were grouped according to marital status,number of births, number of breastfeeding children , total breastfeeding time, which breast they use dominant for breastfeeding, last breastfeeding date . Their internal mammary arteries were evaluated by colour doppler ultrasound , one week after the end of the menstruation , resistive index were calculated by measuring the flow of IMAs . 1 volunteer's IMA flow couldn't measure and she didn't include in the resistive index comparisons. When we compare married women's IMA resistive index to single women's IMA resistive index, the difference was significant between two groups.comparison of total breastfeeding time and the resistive index of the left and right IMA , resistive index were decreased during total breastfeeding time were increased . we didn't see a statistically difference between breastfeeding women's nondominant breasts' IMA resistive index and dominant breasts' IMA resistive index . A weak negative correlation was found between age and IMA resistive index. The result of our study , breastfeeding is significantly reduse the IMA resistive index . we found that , IMA resistive index was decreasing while total breastfeeding time and age are increasing . Key Words : Breastfeeding , internal mammary artery, resistive index .
