Emergency care for brain AVM bleeding using a hybrid neurosurgical operating room

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, multicenter registry enrolling adults with acute intracranial hemorrhage thought to be caused by cerebral arteriovenous malformation. Patients treated in the hybrid neurosurgical operating room may receive emergency cerebral angiography, neurointerventional embolization, microsurgical resection of the AVM, and/or minimally invasive hematoma evacuation as clinically indicated. The study will collect clinical and procedural data to characterize indications, workflows, and short‑term functional outcomes. The goal is to develop standardized diagnostic and treatment protocols for emergency AVM hemorrhage management in the hybrid‑OR setting.
