Endovascular intervention via a venous approach, or trans-venous embolization (TVE), has been increasing employed in the management of intracranial vascular lesions such as arteriovenous malformations (AVMs) and dural arteriovenous fistulas (DAVFs). Current pre-procedural planning is limited by overlapping, complex vascular anatomy and a lack of quantitative hemodynamic feature characterization. Using novel 4D flow MRI methods, high-resolution retrograde venous flow mapping with anatomical detail and dynamic flow fields can provide valuable information prior to TVE. We will present our institutional experience using this method in representative intracranial vascular lesions.
