Résumé

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. 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. This illustrative video highlights the role of microsurgery as a feasible therapeutic strategy for complete resection of cerebellar AVMs after endovascular embolization.

BACKGROUND 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 METHODS
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 CONCLUSIONS
This illustrative video highlights the role of microsurgery as a feasible therapeutic strategy for complete resection of cerebellar AVMs after endovascular embolization.
