The median nidus size was 5 cm (range 4\u20136 cm). Three patients had grade III lesions according to the Spetzler-Martin classification, two were grade IV, and one was grade V. Four patients had draining veins with multiple efferent veins with each collecting vein, one patient had multiple efferent veins with one collecting vein, and one patient had one efferent vein with a long bifurcation. pTVE achieved partial occlusion in all cases without any hemorrhagic complications. One patient had the AVM totally occluded with two sessions of pTVE. Decision-making was facilitated by creating subcategories of venous angioarchitecture and detailing the technical particularities in the corresponding category.<\/jats:p>\n
