Veno-Venous Extracorporeal Lung Assist with Concurrent Distal Aortic Perfusion: Repair of Ruptured Aorta in a Patient with Dense ARDS

Abstract

Extracorporeal lung assist (ECLA) allowed surgical repair of a ruptured descending thoracic aorta to be performed in a patient with profound respiratory failure. Dense acute respiratory distress syndrome (ARDS) developed during his 15-day hospitalization at a regional trauma center. After transfer to a Level I facility, an additional injury was diagnosed: traumatic rupture of the aorta, contained within a pseudoaneurysm. ECLA by the veno-venous route was required immediately preoperatively and distal aortic perfusion was performed during the aortic repair. Despite deflation of the left lung, the patient was oxygenated and ventilated adequately during surgery. Cross-clamp time was 48 minutes. The patient was weaned from ECLA by the fifth postoperative day. To our knowledge, this is the first report of concurrent veno-venous pulmonary support with distal aortic perfusion.
