Clampless off-pump coronary artery bypass prevents early post-operative neurologic injury compared to on-pump: a propensity score matched analysis

Abstract

Unaortic coronary artery bypass with all arterial grafts proved to prevent early neurologic injury. Various devices for clampless proximal anastomosis of venous grafts were associated with an increased risk of microembolism. The Cardica PAS-Port is a new, fully automated device that might be able to obtain safe proximal aorto-venous connection without an increased risk of micro-or macro embolism. We evaluated early post-operative neurologic outcome in a matched population following clampless OPCAB (CCAB) or on-pump CABG.
