Delayed retroperitoneal hemorrhage during veno‐venous extracorporeal membrane oxygenation: a case report

There are several reports of retroperitoneal hemorrhage induced by percutaneous femoral cannulation for extracorporeal membrane oxygenation (ECMO). However, there are no reports of delayed retroperitoneal hemorrhage, which develops a few days after ECMO initiation and is unrelated to the ECMO cannulation. Herein, we report a rare case of delayed retroperitoneal hemorrhage during veno‐venous extracorporeal membrane oxygenation (VV‐ECMO)
