Simplified circular aortotomy in aortocoronary bypass operations
AJ Surmak and A Kantrowitz
Adaptation of a rongeur technique facilitates aortotomy in aortocoronary
bypass operations. A single motion with a double-action duckbilled rongeur
produces a smooth-walled, symmetrical aortotomy which varies in shape
predictably according to the angle at which the rongeur is held relative to
the axis of the aorta.
