Figure 2: Digital subtraction angiogram images anterior-posterior projection (a) taken after cannulation of right L3 lumbar artery show the dural arteriovenuos fistula (short thick arrow) with a prominent ascending perimedullary venous channel (thin arrows). Post-N-butyl cyanoacrylate embolization check angiogram (b) shows complete embolization of the fistula and feeding branch with no residual opacification of the arteriovenous fistula
