epiaortic scanning
Intraoperative ultrasound examination of the ascending aorta to detect atherosclerotic disease and guide cannulation strategy.
Full Definition
Epiaortic scanning is an intraoperative ultrasound technique performed directly on the ascending aorta and aortic arch to identify atherosclerotic plaques, calcifications, and other pathologic conditions that may not be detectable by palpation or preoperative imaging. This technique is crucial in preventing embolic complications during cardiac surgery by allowing surgeons to modify their cannulation strategy, cross-clamp placement, or even convert to off-pump techniques when severe atherosclerosis is detected. The procedure involves using a sterile ultrasound probe to systematically examine the entire ascending aorta and arch, providing real-time assessment of vessel wall integrity and plaque burden.
