Extra corporal membrane oxygenation in general thoracic surgery: a new single veno-venous cannulation
- 4.1k Downloads
Extracorporeal membrane oxygenation (ECMO) is used in severe respiratory failure to maintain adequate gas exchange. So far, this technique has not been commonly used in general thoracic surgery. We present a case using ECMO for peri-operative airway management for pulmonary resection, using a novel single-site, internal jugular, veno-venous ECMO cannula.

Lung transplantation was discussed but the patient was not listed because she did not have respiratory end-stage disease. A multidisciplinary decision was made to proceed with pulmonary resection under peri-operative VV-ECMO support with the Avalon cannula. This strategy made it possible to cease lung ventilation during surgery and created an option to bridge the patient to transplantation in case of postoperative respiratory failure. Pre-lung transplant evaluation was carried out before surgery.
The double-lumen jugular Avalon catheter (23F) was connected to a heparin-coated ECMO circuit consisting of a rotary pump and a polymethylpentene oxygenator. A 3.0 liters/min blood flow was easily achieved allowing sufficient O2and CO2transfers. The patient underwent uneventful segmentectomy and was extubated at the end of surgery. ECMO support weaned off after achieving satisfactory gas exchange 12 hours post-operatively. The 10 months follow up was satisfactory. FEV1 predicted was 38%. without recurrence of haemoptysis.
ECMO support is increasingly being utilised in the management of severe respiratory failure  as a bridge to lung transplantation  and in management of post-transplant primary graft dysfunction . VV ECMO usually requires a dual site implantation. This new single-site cannulation technique through internal jugular vein brings obvious benefits with the poster-lateral thoracotomy position and allows the maintenance of adequate gas exchange during surgery.
Two thoracic surgical cases have been reported using dual-site bilateral femoral VV ECMO. The first one was for curative surgery in a patient with papillary thyroid carcinoma invading the trachea . The second for carinal resection and reconstruction after left pneumonectomy .
To our knowledge, this innovative technique of cannulation has been reported in lung transplantation [2, 3], but never reported in general thoracic surgery. Despite its potential risks , such a cannulation remains an effective alternative airway management option in patients with a significant lung function insufficiency who require pulmonary resection. Furthermore, the use of ECMO support even in thoracic surgery should be limited to institutions that have multi-disciplinary cardiac and vascular department with extensive knowledge in ECMO technology and the management of complications.
