Advances in perfusion technology--an overview.
The introduction of minimally invasive approaches to cardiac surgery offered the opportunity to reduce patient's pain associated with median stemotomy as well as infection and postoperative bleeding. This technique required the use of one small venous cannula necessitating the implementation of kinetic assisted venous drainage (KAVD). However, KAVD proved costly due to the use of a centrifugal pump and could be de-primed if air was introduced into the venous line. Vacuum assisted venous drainage (VAVD), an easy to learn technique, was proved to be a better, safe and less expensive alternative as it required lower prime and small cannulae. Blunt trauma could also be avoided as large cannulae were not used.
