AimAcute aortic dissection (AAD) has been considered a contraindication for extracorporeal cardiopulmonary resuscitation (ECPR). However, studies are lacking regarding the epidemiology and effectiveness of ECPR for AAD. We aimed to examine whether ECPR for AAD during refractory cardiac arrest is effective.MethodsUsing the Japanese Diagnosis Procedure Combination inpatient database from July 2010 to March 2018, we identified all emergently hospitalized adults who received ECPR on the day of admission and all AAD patients who received cardiopulmonary resuscitation on the day of admission. ECPR was defined as receiving both cardiopulmonary resuscitation and percutaneous extracorporeal membrane oxygenation. Outcomes were in-hospital mortality and neurological outcomes. We calculated the incremental cost-effectiveness ratio of ECPR for AAD.ResultsWe identified 398 AAD patients with ECPR, 9840 non-AAD patients with ECPR, and 9709 AAD patients with cardiopulmonary resuscitation but not ECPR. The incidence of AAD among the patients with ECPR on the day of admission was 3.9%. In-hospital mortality was 98% in AAD patients with ECPR, 79% in non-AAD patients with ECPR, and 98% in AAD patients with cardiopulmonary resuscitation but not ECPR. Seven AAD patients survived to discharge after ECPR; of these, six patients had good neurological outcomes at discharge. The incremental cost-effectiveness ratio of ECPR for AAD was estimated at 161,504 US dollars per quality-adjusted life year gained.ConclusionECPR successfully improved outcomes and/or facilitated surgery for a small number of AAD patients with refractory cardiac arrest; however, the cost burden of ECPR for AAD patients may be unacceptably high.Copyright © 2020 Elsevier B.V.
