Pediatric posterior fossa arteriovenous malformation treatment

Microsurgical resection remains a good option for posterior fossa arteriovenous malformation treatment in one setting. The drawback of endovascular embolization is the lower rates of nidus obliteration. Although stereotactic radiosurgery is a safe alternative, it takes several years to achieve the treatment goal all the while predisposing the patient to the risk of arteriovenous malformation rupture.

Accurate localization and visualization remain challenging for microsurgical treatment of posterior fossa AVMs.

Small size of a nidus, prone position, and proximity to eloquent areas make these lesions particularly difficult to localize and resect.
