Imagining of internal mammarian artery by preoperative doppler ultrasound and intraoperative measurements of lima in diabetic patients

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 grafting (CABG), to compare preoperative left IMA CDUS and intraoperative diameter and volume values and to compare LIMA diameters and volume values in diabetics to nondiabetics patients undergoing CABG.61 men and 23 women whom ages range between 40 and 75 were placed in this study. The mean age at diabetic patient group was 61,8±10,2 while at nondiabetic group was 60,2±12,7. Bilateral IMA were evaluated by CDUS for diameter, volume, end diastolic velocity (EDV), peak systolic velocity (PSV) and resistive index (RI) from 5th or 6th intercostal areas. In operation room, after harvesting IMA grafts the volume measured by 1 minute bleeding volume value was measured by collecting in to volumetric cups. And also the diameter of IMA was measured with coronary probes.Statistically significant differences were found between left and right IMA and preoperative and intraoperative diameter and volume values of left IMA.When we compare diabetic patients to nondiabetic patients the diastolic tension and LIMA sistolic velocity measured by doppler US and intraoperative measurements of diastolic tention were statically significant diffrerent in group 1 and group 2.In nondiabetic patients, by using preoperative CDUS, we found 3 monofazic flows ( %5,1 ). At that patients, harvested LIMA graft paterns were weak and vessel structures were thin, as a result they weren?t used as a graft for coronary bypass.In our study, we believe that, data we gathered by doppler of IMA may help graft selection. Also we believe that diabetes does not have an important negative effects on IMA.Keywords: Color Doppler Ultrasonography- Internal mammarian artery- Diabetes mellitus.
