Summary
Intraoperative extracorporeal membrane oxygenation (ECMO) during lung transplantation (LTx) can be achieved with a cost-effective hybrid circuit. This approach allows seamless conversion to full cardiopulmonary bypass (CPB) if necessary, without interrupting extracorporeal circulation (ECC).
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Transplantation Medicine
Background:
- Intraoperative extracorporeal circulation (ECC) support via extracorporeal membrane oxygenation (ECMO) is standard in high-volume lung transplantation (LTx) centers.
- Dedicated ECMO circuits are costly and limit the ability to perform full cardiopulmonary bypass (CPB).
Purpose of the Study:
- To describe a novel technique for venoarterial ECMO during LTx.
- To introduce a less-expensive hybrid circuit enabling immediate conversion to full CPB.
Main Methods:
- Implementation of venoarterial ECMO during LTx using a hybrid circuit.
- The hybrid circuit design facilitates rapid transition to full CPB without ECC interruption.
Main Results:
- The described hybrid circuit provides a cost-effective alternative for ECMO support during LTx.
- The technique allows for uninterrupted ECC and immediate conversion to CPB when clinically indicated.
Conclusions:
- This hybrid circuit technique offers an efficient and economical approach to intraoperative ECC support in lung transplantation.
- The described method enhances surgical flexibility by allowing seamless transition between ECMO and CPB.
