Rationale:
Gestational trophoblastic neoplasms are rare and include multiple different types of tumors such as hydatidiform moles, placental site trophoblastic tumors, and choriocarcinoma. Metastatic choriocarcinoma is well described with an excellent prognosis when treated appropriately with chemotherapy. The most common location for metastatic disease is the lungs which can unfortunately lead to severe acute respiratory distress syndrome (ARDS) in the most severe cases.
Patient concerns:
Metastatic cancer has historically been a contraindication for the use of extracorporeal life support (including extracorporeal membrane oxygenation or extracorporeal membrane oxygenation [ECMO]). With advancing technology and medicine, this contraindication has been called into question. Prior case reports describe the use of ECMO in complicated cases of metastatic cancer and even choriocarcinoma with lung metastasis and refractory ARDS.
Diagnoses:
We describe a case in which a patient with choriocarcinoma in viable pregnancy developed lung metastasis and ARDS.
Interventions:
The patient was managed with venovenous ECMO successfully.
Outcomes:
The patient was cannulated for VV-ECMO for 14 days with subsequent full pulmonary recovery.
Lessons:
The purpose of this work is to help providers understand the broad utility of ECMO and the need to assess candidacy for this therapy on a case by case basis, even in the setting of metastatic cancer.
