Why the study?
Preoperative enhanced CT and angiography have limitations in identifying target vessels and assessing vascular quality during cardiovascular surgery.
Intraoperative 15-MHz high-frequency epicardial ultrasound has potential utility for detecting small vessels and assessing vascular structure during cardiovascular surgery, particularly coronary artery bypass surgery.
May support intraoperative vascular assessment in surgery; leaves open clinical benefit pending prospective trials.
In cardiovascular surgery, it is important to identify the target vessel and to assess the quality of vascular structure.Preoperative enhanced computed tomography (CT) and angiography give us that information; however, we sometimes encounter difficulties due to limitation of those preoperative examinations.Intraoperative use of 15-MHz high-frequency epicardial ultrasound with small probe has a great potential to detect small vessels and it will give us benefits in cardiovascular operations, especially coronary artery bypass surgery.
