[Objective] This study aimed to examine the effects of age on the survival of patients with severe respiratory failure treated with veno-venous extracorporeal membrane oxygenation (V-V ECMO). [Methods] We retrospectively analyzed adult patients treated with V-V ECMO at the Maebashi Red Cross Hospital between January 2013 and July 2020. The patients were divided into three groups:patients aged ‹65 years (group Y), those aged 65‒74 years (group E), and those aged 75 years and older (group L). We compared the 6-month survival rates in each group and calculated their survival rates for each 5-year age group. [Results] A total of 89 patients underwent V-V ECMO during the specified period, but 19 were excluded. 30, 23, and 17 cases were assigned in groups Y, E, and L, respectively. The 6-month survival rates were 76.7%, 60.9%, and 52.9% in groups Y, E, and L, respectively. The survival rate peaked in the 50s and tended to decrease with increasing age. [Conclusions] The older groups had a worse prognosis, but the difference was not significant. With appropriate patient selection, V-V ECMO may be useful in the elderly. A large-scale study to evaluate the pros and cons of V-V ECMO in the elderly is warranted.
