bicaval cannulation
Venous drainage technique using separate cannulas in both the superior and inferior vena cavae.
Full Definition
A cardiopulmonary bypass technique where venous drainage is achieved through separate cannulas placed in both the superior vena cava (SVC) and inferior vena cava (IVC), rather than a single right atrial cannula. This method provides superior venous drainage, allows for complete isolation of the right heart, and is essential for procedures requiring access to the right atrium or tricuspid valve. It also prevents air entrainment and provides better surgical exposure.
Usage
Usage note: Preferred spelling uses 'bicaval' as one word, not 'bi-caval'.
In Context
- "Bicaval cannulation was performed to provide optimal exposure for the tricuspid valve repair." — Operative note
- "The perfusionist confirmed adequate venous return through both bicaval cannulation sites." — Perfusion record
