Same patient as in Fig. 1. a Emergency angiography with selective catheterisation of the right renal artery confirmed the presence of an upper renal pole AVM. b Two major feeding arterial branches supplied the AVM. Rapid venous filling through enlarged pool-like vascular structures was demonstrated. Both sites were successfully embolised with metallic coils of 3 × 2.6 (n = 3), 4 × 4.0 (n = 3) and 6 × 2.6 (n = 1) mm diameter (2D Helical-35, Boston Scientific, Cork, Ireland). The procedure was uneventful, haematuria subsided immediately and the patient recovered fully within the next few days
