Endoscopic Doppler for detecting vessels in closed chest bypass grafting HEART SURGERY FORUM Falk, V., Fann, J. I., Grunenfelder, J., Burdon, T. A. 2000; 3 (4): 331-333

Abstract

A new method of endoscopic ultrasonography during endoscopic bypass grafting is described. Using a 7.5 MHz ultrasonic catheter (AcuNav, Acuson, Mountain View, CA) that was introduced through a 5mm port and manipulated by robotically enhanced endoscopic instruments, detection of the internal thoracic artery (ITA) and the left anterior descending (LAD) artery was possible through layers of fat and muscle in a canine model.
