Venoarterio-Venous (VA-V) ECMO Configuration: A Single-Center Experience

Patients in respiratory failure on VV ECMO may develop cardiovascular dysfunction necessitating additional hemodynamic support, while patients in cardiovascular failure on VA ECMO may require additional respiratory support for concurrent gas exchange abnormalities. A hybrid venoarterio-venous (VA-V) configuration provides both cardiac support via a traditional arterial reinfusion cannula and respiratory support via an additional venous reinfusion limb. We describe our single center experience using VA-V ECMO for patients (n = 14, median age 54) with combined cardiopulmonary failure or differential hypoxemia. Patients were treated with ECMO support for a median of 148.2 (IQR 122.6 – 174.4) hours, consisting of 0 (IQR 0 – 1.8) hours of VA and 92.4 (IQR 58 – 115) hours of VA-V followed by 46 (IQR 0 – 95.5) hours of VV support. Of these 14 patients, 11 survived to decannulation (79%) and 9 survived to hospital discharge (64%).

We describe two cases of profound cardiogenic shock complicating acute myocardial infarction (CSAMI) requiring mechanical circulatory support (MCS) with venoarterial extracorporeal membrane oxygenation (VA-ECMO) allowing complex, high-risk, and staged percutaneous interventions with successful decannulation but with unfortunate outcomes.

Conventional treatment of respiratory failure involves positive pressure ventilation that can worsen lung damage. Extracorporeal membrane oxygenation (ECMO) is typically used when conventional therapy fails. In this study, we evaluated the use of venovenous (VV)-ECMO for the treatment of severe pediatric respiratory failure at our institution. A retrospective analysis of pediatric patients (age 1–18) placed on ECMO in the last 15 years (1999–2014) by the pediatric surgery team for respiratory failure was performed. Five pediatric patients underwent ECMO (mean age 10 years; range, 2–16). All underwent VV-ECMO. Diagnoses were status asthmaticus (2), acute respiratory distress syndrome due to septic shock (1), aspergillus pneumonia (1), and respiratory failure due to parainfluenza (1). Two patients had severe barotrauma prior to ECMO initiation. Average oxygenation index (OI) prior to cannulation was 74 (range 23–122). No patients required conversion to VA-ECMO. The average ECMO run time was 4.4 days (range 2–6). The average number of days on the ventilator was 15 (range 4–27). There were no major complications due to the procedure. Survival to discharge was 100%. Average follow up is 4.4 years (range 1–15). A short run of VV-ECMO can be lifesaving for pediatric patients in respiratory failure. Survival is excellent despite severely elevated oxygen indices. VV-ECMO may be well tolerated and can be considered for severe pediatric respiratory failure.

Current Therapies

Lung disease is America’s third largest killer, and responsible for one in seven deaths [1]. Most lung disease is chronic, and respiratory support is essential. Current therapies for the respiratory failure include mechanical ventilation and bed-side extracorporeal membrane oxygenation (ECMO) devices which closely simulate the physiological gas exchange of the natural lung.
