Ruptured cerebral arteriovenous malformations: Outcomes analysis after microsurgery

International audience; OBJECTIVE: Our study aimed to evaluate the functional outcome and the risk of postoperative remnant in patients with rAVM after microsurgical treatment.METHODS: This is a retrospective of 139 consecutive patients operated for a rAVM between 2002 and 2012 in our institution. The age at diagnosis and the WFNS score were recorded for each patient before treatment. All patients were re-evaluated 3 months after treatment using mRS scale. Conventional angiography was performed in the first 2 postoperative weeks and then a year later to detect any remnant or recurrence.RESULTS: The mean age at diagnosis was 30.8 years (range 4-69 SD: ±5) and 44 patients had an age at diagnosis 2, SPM grade>2 and preoperative evaluation limited only to CT angiography in emergency situation (p
