CHILDHOOD DURAL ARTERIOVENOUS-FISTULAS OF THE POSTERIOR DURAL SINUSES - 3 CASE-REPORTS AND LITERATURE-REVIEW

WE REPORT THREE cases of posterior dural sinus arteriovenous fistulae in pediatric patients and a literature review of 18 additional cases. These lesions carry a grave prognosis with a reported mortality of 38% and with an historical anatomic cure of only similar to 9%. With advanced neurointerventional techniques and increased knowledge of their pathophysiology, these highly complicated lesions can be more safely treated with a strategy that involves extensive preoperative embolization and surgical excision. The importance of delaying direct surgery with conservative measures or interventional radiological treatment, including preoperative transarterial and transvenous embolization, is critical in the management of these lesions.
