BackgroundIntracranial hemorrhage (ICH) is a potential complication associated with extracorporeal membrane oxygenation (ECMO), which has been increasingly utilized in recent years. A paucity of data exists describing patient outcomes following invasive neurosurgical interventions in patients receiving ECMO therapy. The purpose of this study was to assess the clinical and functional outcomes in patients who underwent cranial neurosurgery for the management of an ECMO-associated intracranial complication.MethodsThis was a single-institution retrospective review of adult patients who underwent craniotomy or craniectomy after sustaining an intracranial hemorrhagic complication of ECMO therapy from 2008 to 2023. Anticoagulation status, operative indication, surgical details, postoperative course, and functional outcome were recorded. A systematic review of the prior literature was performed to contextualize our institutional results within previous reports.ResultsFour adult patients were identified at our institution who underwent craniotomy or craniectomy for the neurosurgical management of an ECMO-associated ICH. One patient (25%) ultimately made a satisfactory recovery (Modified Rankin Scale score 3 at 1 year). The surviving patient had a notably higher Glasgow Coma Scale (7T vs. 3T), had not received anticoagulation at the time of surgery, and did not experience postoperative reaccumulation or expansion of their hemorrhage, distinguishing factors from the other 3 included. Review of the existing literature identified 15 adult patients who underwent craniotomy while receiving ECMO therapy, of which 4 (26.7%) had a long-term favorable neurologic outcome.ConclusionsThe overall prognosis following neurosurgical intervention for the management of ECMO-associated intracranial complications was poor in our case series, which was corroborated by our literature review.Copyright © 2024 The Author(s).
