TRENSH Treatment in Pig AVMs
The realistic, dynamic, high flow transition of opacified blood is appreciated on this cine angiogram at 30 frames per second demonstrating components of the pig AVM model. Upon injection of the left common carotid artery there is fast shunting from the AF (left ascending pharyngeal artery), across the nidus (bilateral retia mirabilia, magnified view), and emptying into the DV (right ascending pharyngeal artery) owing to the sump effect of the right carotid-jugular fistula (not shown). Subtracted views are shown in real time.
