Background
Despite various treatments to control intracranial pressure (ICP) after brain injury, patients may present a late onset of high ICP or a poor response to medications. External lumbar drainage (ELD) can be considered a therapeutic option if high ICP is due to communicating external hydrocephalus. We aimed at describing the efficacy and safety of ELD used in a cohort of traumatic or non-traumatic brain-injured patients.
Methods
In this multicentre retrospective analysis, patients had a delayed onset of high ICP after the initial injury and/or a poor response to ICP treatments. ELD was considered in the presence of radiological signs of communicating external hydrocephalus. Changes in ICP values and side effects following the ELD procedure were reported.
Results
Thirty-three patients with a median age of 51 years (25-75th percentile: 34–61 years) were admitted after traumatic (n = 22) or non-traumatic (n = 11) brain injuries. Their initial Glasgow Coma Scale score was 8 (4–11). Eight patients underwent external ventricular drainage prior to ELD. Median time to ELD insertion was 5 days (4–8) after brain insult. In all patients, ELD was dramatically effective in lowering ICP: 25 mmHg (20–31) before versus 7 mmHg (3–10) after (p < 0.001). None of the patients showed adverse effects such as pupil changes or intracranial bleeding after the procedure. One patient developed an ELD-related infection.
Conclusions
These findings indicate that ELD may be considered potentially effective in controlling ICP, remaining safe if a firm diagnosis of communicating external hydrocephalus has been made.
