Objectives:
Extracorporeal membrane oxygenation (ECMO) is often withheld in patients with significant neurologic injury or recent neurosurgical intervention due to perceived futility. Studies of neurosurgical interventions before or during ECMO are limited to case reports or single-center series, limiting generalizability, and outcomes in this population are unknown. We therefore sought to report the outcomes of ECMO patients with acute neurosurgical interventions at four high-volume ECMO and comprehensive stroke centers.
Design:
Retrospective case series.
Setting:
Four academic tertiary referral hospitals in the United States.
Patients:
Adults (n = 24) having undergone neurosurgical procedures before or during ECMO.
Interventions:
None.
Measurements And Main Results:
We retrospectively reviewed adults at four institutions who had undergone neurosurgical procedures immediately before or during ECMO from 2015 to 2023. The primary outcome was survival to hospital discharge. Secondary outcomes included favorable neurologic outcome (Cerebral Performance Category 1 or 2) and neurosurgical complications. Twenty-four of 2957 ECMO patients (0.8%) were included. Primary indications for neurosurgical intervention included traumatic brain (n = 8) or spinal (n = 3) injury, spontaneous intracranial hemorrhage (n = 6), and acute ischemic stroke (n = 5). Procedures included extraventricular drain (EVD) and/or intracranial pressure monitor placement (n = 10), craniectomy/craniotomy (n = 5), endovascular thrombectomy (n = 4), and spinal surgery (n = 3). Fifteen patients (63%) survived to hospital discharge, of whom 12 (80%) were discharged with favorable neurologic outcomes. Survival to discharge was similar for venoarterial and venovenous ECMO patients (8/12 vs. 7/12; p = 0.67) and those who had neurosurgery before vs. during ECMO (8/13 vs. 7/11; p = 0.92). One patient (4%) experienced a neurosurgical complication, a nonlethal tract hemorrhage from EVD placement. Survival to discharge was similar for neurosurgical and nonneurosurgical ECMO patients at participating institutions (63% vs. 57%; p = 0.58).
Conclusions:
Patients with acute neurologic injury can feasibly undergo neurosurgery during ECMO or can undergo ECMO after recent neurosurgery. Larger studies are needed to fully understand risks for bleeding and other procedure-related complications.
