Duplex doppler ultrasound of bilateral internal mammarian and carotid arteries and comparison of diameter and volume values that gathered by preoperative doppler ultrasound and during intraoperative evaluation of left internal mammarian artery

The purpose of this study is to evaluate bilateral internal mammarian arteries (IMA) by color Doppler US (CDUS) that is the ideal vascular greft for coronary artery bypass surgery (CABS), to make correlations between IMA, common (CCA) and internal carotid arteries? (ICA) parameters and to compare preoperative left IMA CDUS and intraoperative diameter and volume values.49 men and 17 women whom ages range between 40 and 77 (mean 60,72±10,64) were placed in this study. Bilateral IMA were evaluated by CDUS for diameter, volume, end diastolic velocity (EDV), peak systolic velocity (PSV) and resistive index (RI) from 5 or 6 intercostal areas. Carotid arteries were revealed for PSV, EDV, RI and thickness of intima-media by CDUS.Statistically significant differences were found between left and right IMA and between preoperative and intraoperative diameter and volume values of left IMA. There were positive correlations between RI values of right IMA, CCA and ICA.It was considered as the findings that gathered in this study before CABS are helpful to choose and decide the most appropriate IMA. It appears that the parameters related with CCA and ICA are not effective during the evaluation of IMA.Keywords: Color Duplex Doppler Ultrasonography- Internal mammarian artery- Carotid artery
