Treatment of Cerebral Arteriovenous Malformation in Ruptured Brain AVM
A ruptured brain arteriovenous malformation (bAVM) represents an acute hemorrhagic presentation that substantially elevates the risk of recurrent bleeding and drives the indication for definitive intervention.
Clinical scenario
Patients with ruptured bAVMs carry a meaningfully increased risk of recurrent hemorrhage compared with those whose lesions remain unruptured. This elevated rebleeding risk is the primary clinical rationale for pursuing active treatment in this population.
Treatment approach (partial overview)
Definitive management is directed at eliminating the AVM through interventional means — which may include surgical, endovascular, or radiosurgical approaches, used individually or in combination. Specific consideration is also given to reducing the immediate risk of rerupture related to associated vascular structures. The complete sequence, selection criteria, and timing recommendations are in the full protocol.
Treatment goal
Target: Complete obliteration of the bAVM nidus and arteriovenous shunt.

Patients with ruptured bAVMs have an increased risk of recurrent hemorrhage relative to those with unruptured lesions.
This finding is the primary reason cited for treatment of ruptured bAVMs.
Treatment options are identical for those with unruptured bAVMs: surgical resection, embolization, SRS, or a combination of these methods.
As mentioned above, targeted embolization of nidal or perinidal aneurysms may reduce the risk of rerupture.
The definitive treatment of bAVMs should be complete elimination of the nidus and the arteriovenous shunt.
