Abstract:
Thoracic vascular ultrasound was used to evaluate left internal mammary artery to left anterior descending artery (LAD) bypass (LIMA) blood flow pattern in CABG patients. A transthoracic vascular transducer (5～10 MHz) was placed in the second rib space left to the sternum. Doppler spectrum was obtained under 2 D color Doppler image guide. Systolic and diastolic flow was analysed as systolic peak velocity (SPV), systolic velocity time integrate (SVTI), diastolic peak velocity (DPV) and diastolic velocity time integrate (DVTI). Successful examination was done in 106 patients ( 106/110, 94% ) , In patients with patent LIMA, Doppler spectrum showed a notable diastolic flow spectrum. The results of this study suggested that trans thoracic echocardiographic examination could provide avaluable blood flow information. A notable diastolic flow spectrum can be taken as a sign of satisfactory LIMA coronary diastolic myocardium perfusion.
