Trans-arterial embolization of left renal AVM A – Left renal arteriography showing the AVM (orange arrowhead) with nidus. Arterial feeders are difficult to individualized B, C & D – Microcatheterization of interlobar and arcuate arterial branches (white arrows) and embolization of 2 arterial branches feeding the AVM (orange arrowhead) with 2 detachable micro-coils (blacks arrowheads).Control left renal arteriography (D) showing persistent opacification of the AVM nidus (orange arrowhead). E – Microcatheterization of an interlobar artery (white arrow) feeding the AVM (orange arrowhead) and embolization by 0,8ml of Ethylene–Vinyl alcohol (EVOH) copolymer. F Control left renal arteriography showing a close-to-complete occlusion of the AVM nidus using 2 micro-coils (black arrowheads) and EVOH copolymer (black arrow). At the end of the procedure, a very small portion of the circulating nidus remains (orange arrow), which we have chosen not to treat in order to avoid more extensive renal devascularization
