Clinical Activities


Neurovascular Emergencies

A full 24/7 coverage for neurovascular emergencies (acute neurological deficit, ischemic stroke, hemorrhagic stroke, etc) is offered at CHUM.

In the greater region of Montreal, an EMS redirection system allows patients with a suspicion of severe stroke to be brought directly to CHUM, in order to minimize treatment delays. When medically stabilized, patients are repatriated the most appropriate acute care hospital, based on their clinical characteristics and geographical origin.

Coverage of neurovascular emergencies in 18 other centers in south-western region of the province is also assured by our team in all time by teleconsultation.

In-patient Stroke Unit

The Louise-Hélène Lebrun stroke unit at CHUM receives more than 850 admitted patients with ischemic or hemorrhagic stroke yearly.

Across the hospitalisation wards in vascular neurology, interventional neuroradiology and vascular neurosurgery, approximately 300 additional patients are admitted yearly due to subarachnoid hemorrhage and/or emergent or elective interventional treatment of neurovascular lesions (arterial stenosis, arterioveinous malformation, dural arterioveinous fistula, cavernoma, etc).

Our innovative multidisciplinary project, Parcours Locomotive, was developed to stimulate patient recovery during their hospital stay through a series of planned exercises, stations and external stimuli intended to motivate patients in their post-stroke journey


Neurovascular Outpatient Clinic

All our physicians participate in the assessment and follow-up of patients necessitating neurovascular care on an outpatient basis.

Our team offers specialized expertise across the entire spectrum of neurovascular disorders: ischemic or hemorrhagic strokes, arterial dissection, vasculitis with CNS involvement, cerebral veinous thrombosis, intracranial or extracranial arterial stenosis, etc.
