Case 23, a patient with treated DAVF with residual Borden type I shunt. Case 23, a patient with treated DAVF with residual Borden type I shunt. Anteroposterior (A–E) and submentovertex (F–J) MIPs of consecutive whole-head volumes with an effective frame rate of 2 s. K and L are DSA anteroposterior and lateral views of an injection into the left external carotid artery. A persistent DAVF is located at the left sigmoid sinus, with residual shunt into the left transverse sinus and across the torcula to the right transverse sinus and down the right jugular vein (arrows). The left jugular vein is occluded. Endovascular coils from previous treatment can be seen overlying the left transverse sinus (open arrow) on DSA. Note the normal (later) filling of the superior sagittal sinus at 6 s in Figs D and I (curved arrow). In this case, reader 1 incorrectly suspected CVR. R.I. Farb et al.
