Effects of Previously Well-Developed Collateral Vessels on Left Internal Mammary Artery Graft Flow after Bypass Surgery

AUTOR(ES)
RESUMO

Transthoracic Doppler ultrasonography can assess left internal mammary artery patency and flow after coronary artery bypass grafting. We aimed to show, by transthoracic Doppler ultrasonography, the early effects upon left internal mammary artery graft flow of preoperative collateral vessels supplying the left anterior descending artery.
