Concurrent cervical dural and multiple perimedullary arteriovenous fistulas presenting with subarachnoid hemorrhage: The source of bleeding was invisible at initial angiography.

CONCLUSION: A part of the whole AVFs or the source of bleeding may be invisible in the acute stage just after hemorrhage. Repeated angiography is necessary to diagnose such complex AVFs especially in case of an SAH and treatment should be performed during the subacute stage. PMID: 28217381 [PubMed - in process]
