Key result
VA ECMO assistance during huge mediastinal tumor resection combined with SVC replacement was feasible and safe, maintaining stable hemodynamics without postoperative neurological complications.
Why the study?
Surgical resection of huge mediastinal tumors compressing or invading the vena cava presents formidable anesthetic challenges with high risks of cardiorespiratory compromise, hemodynamic fluctuations, and perioperative death.

VA ECMO provides safe and feasible hemodynamic support during high-risk huge mediastinal tumor resections involving SVC replacement.
Supports feasibility of venoarterial ECMO for high-risk mediastinal tumor resections with vascular involvement; hypothesis-generating pending prospective evaluation.
As to huge solid mediastinal tumor which direct compression or invasion of the superior/inferior vena cava (SVC/IVC), surgical resection remains the main lifesaving treatment. However, it would present formidable anesthetic challenges due to the extremely high risks of cardiorespiratory compromise, drastic hemodynamic fluctuations and death at all perioperative stages. Here, we report a case of huge anterior mediastinal tumor resection combined with SVC replacement under the assistance of venoarterial extracorporeal membrane oxygenation (VA ECMO), and stable hemodynamics were maintained as well as high internal jugular vein pressure being avoided during the operation procedure. He was weaned off ECMO successfully just after surgery and eventually discharged. No signs of postoperatively neurological complications occurred. Therefore, the use of ECMO assistance in huge mediastinal tumor resection combined with SVC replacement is feasible and safe, which may provide the possibility of surgical treatment for such patients and improve outcomes.

Yu et al. (2024) conducted a case report in Huge anterior mediastinal tumor (n=1). Venoarterial extracorporeal membrane oxygenation (VA ECMO) was evaluated on Feasibility, safety, and postoperative neurological complications. VA ECMO assistance during huge mediastinal tumor resection combined with SVC replacement was feasible and safe, maintaining stable hemodynamics without postoperative neurological complications.
