Pseudoaneurysm of Left Internal Thoracic Artery Graft After Coronary Artery Bypass Grafting: Diagnosis by Transthoracic Echocardiography

Abstract

A cystic lesion between the left internal thoracic artery (LITA) graft and left anterior descending artery (LAD) flow was detected by routine transthoracic echocardiography in a patient after coronary artery bypass grafting. The cystic lesion communicated with the anastomotic site of the LITA graft to LAD, and it was diagnosed as a pseudoaneurysm of the LITA graft by transthoracic echocardiography.
Because pseudoaneurysm of a coronary bypass graft is a potentially fatal complication after coronary artery bypass grafting, it is important to detect the LITA graft flow at the anastomotic site by transthoracic echocardiography in routine examination.
