Fig 2. A 69-year-old woman with a left sigmoid sinus dural AVF presenting with intracranial hemorrhaging.
A and B, Preoperative IADSAs show a sigmoid sinus dural AVF with aggressive leptomeningeal drainage (arrowheads). The main feeding artery is shown to be the occipital artery (arrow). C, Preoperative MRDSA (sagittal) shows early venous filling with a pseudophlebitic pattern (venous congestion; arrowheads). The main feeding artery is shown to be the occipital artery (arrow).
D and E, After TVE, IADSAs show the disappearance of the dural AVF. F, Postoperative MRDSA is unable to detect this shunt.
