@entity2457 ( @entity2457 ) associated with our series of @entity1 with @entity11893 ( @entity11893 ) are analyzed and discussed. We retrospectively analyzed 87 consecutive cases of @entity11893 treated between May 2002 and December 2011 and identified 26 @entity1 with @entity2457 . We gathered information from the clinical case records, angiographic images, MRI on presentation and during follow-up. The findings were analyzed to aid discussion. Among 87 @entity1 treated by multi-stage endovascular embolization, age range from newborn to 19 years, 26(30%) had @entity2457 . In seven @entity1 (8%), @entity2457 were found on initial angiogram and were all into the @entity11893 . Nineteen (21%) @entity2457 found on follow-up angiograms were all into the @entity11893 and distant locations. Sprouting and non-sprouting angiogenesis resulted in the formation of a network of vessels around partially thrombosed @entity11893 , recruiting blood from the surrounding dura mater resulting in a secondary network on the dura mater supplied by the blood vessels of dura mater in the region or from its natural collaterals. Embolization targeting DAVFs was done in 13 (52%) with complete cure in eight (32%) and recurrence in five (20%). Among 12 non-embolized @entity1 (48%), eight (32%) had spontaneous regression with continued treatment of @entity11893 . In others, the @entity2457 either remained stable or progressed. @entity2457 associated with @entity11893 represent the dural response to angiogenic stimuli. They are observed to regress spontaneously or mature while continuing to treat the primary feeders of @entity11893 . It is important to include the external carotid system during angiograms. Persistent @entity2457 with residual @entity11893 that do not have access though the pial vessels are used as a conduit to treat the dural shunt and to achieve obliteration of residual @entity11893 at later stages of treatment.
