Clinical case• 66M b/g gunshot wounds req trauma surgery• Found unconscious, hypoxic and tachycardic, E1V1M4 on arrival, PEARL

PICO question• P: adults with IVH secondary to spontaneous supratentorial
ICH• I: EVD + intraventricular TPA• C: EVD alone• O: mortality, functional outcomes, LoS, complications
(bleeding, ventriculitis)
QUESTION:“In adults with IVH secondary to spontaneous supratentorial ICH,
is intraventricular thrombolysis superior to external ventriculostomy alone?”
