epiaortic scanning
Ultrasound examination of the ascending aorta performed directly on the vessel surface to detect atherosclerotic plaque and guide cannulation strategy.
Full Definition
Epiaortic scanning involves placing a sterile ultrasound probe directly on the ascending aorta during cardiac surgery to assess for atherosclerotic disease, calcification, and mobile debris. This technique helps surgeons select optimal cannulation sites and modify surgical approach to reduce risk of embolic stroke. The examination typically evaluates the entire ascending aorta from root to arch, identifying areas of severe atherosclerosis that may contraindicate standard cannulation or require alternative approaches such as axillary cannulation.
