Extracorporeal membrane oxygenation in a patient with newly diagnosed acute myeloblastic leukaemia presenting with severe respiratory failure.

Veno-venous extracorporeal membrane oxygenation (ECMO) is typically instituted in severe respiratory failure, defined by Lung Injury Score, and caused either by pulmonary or extra-pulmonary reversible disease processes. These processes will have led to acute worsening of oxygenation and/or respiratory acidosis together with an inability to provide safe, lung protective, mechanical ventilation. Patients with underlying chronic immunosuppression or haematological malignancies treated with ECMO for severe respiratory failure have poor short- and long-term functional and survival outcomes. Consequently, in many centres, a diagnosis of haematological malignancy is considered a contraindication to provision of ECMO support for severe respiratory failure. We present a case of a 51-year-old female who attended her local hospital with symptoms suggestive of community-acquired pneumonia. Within a few days, there was progression to severe respiratory failure, initially managed with invasive mechanical ventilation but rapidly deteriorating respiratory failure triggered referral for ECMO support. Initial investigations on ECMO demonstrated features of acute myeloblastic leukaemia with a superimposed community-acquired pneumonia. This was successfully managed with supportive treatment alongside mechanical respiratory therapy and targeted chemotherapy, achieving complete remission and full functional recovery.
