    BackgroundFilum terminale arteriovenous fistula (FTAVF) with multiple shunt points has not been reported in the literature. In previous studies, the angioarchitecture of FTAVFs was always featured with only one single shunt point, and such a uniformity had established the preconceived and conventional understanding of FTAVFs for clinicians.Case DescriptionThe authors describe 2 exceptional cases of FTAVFs with multiple shunt points confirmed by open surgery, which means that the above understanding may lead to misdiagnosis and incomplete treatment in future. The surgery of both cases was performed in a hybrid operating room, and all of shunt points were obliterated with the help of intraoperative digital subtraction angiography.ConclusionsThe exceptional finding of these 2 cases is a renewal of the conventional understanding of FTAVFs, not only for the angioarchitecture of the lesions but also for the treatment strategy.Copyright © 2018 Elsevier Inc.
