Microsurgical treatment for cerebellomesencephalic fissure arteriovenous malformations after multiple sessions of endovascular treatment

BACKGROUND: Arteriovenous malformations (AVMs) are relatively uncommon congenital vascular anomalies, and only 7–15% of AVMs occur in the posterior fossa. Most posterior fossa AVMs clinically present with hemorrhage and are associated with a high risk of neurological deficits and mortality. These ma...

Sumario:BACKGROUND: Arteriovenous malformations (AVMs) are relatively uncommon congenital vascular anomalies, and only 7–15% of AVMs occur in the posterior fossa. Most posterior fossa AVMs clinically present with hemorrhage and are associated with a high risk of neurological deficits and mortality. These malformations are associated with a high incidence of flow-related aneurysms. Endovascular treatment of infratentorial AVMs is challenging in pediatric patients. CASE DESCRIPTION: We describe an 11-year-old female adolescent with cerebellar syndrome [Video 1], who was diagnosed with a cerebellomesencephalic fissure AVM. We observed a sequential increase in the size of the AVM after multiple sessions of endovascular treatment and performed successful microsurgical resection of the lesion. CONCLUSION: This illustrative video highlights the role of microsurgery as a feasible therapeutic strategy for complete resection of cerebellar AVMs after endovascular embolization.
