a During transarterial deployment of second 40 mm × 60 cm Ruby framing coil (black arrow), the first 40 mm × 60 cm Ruby framing coil (white arrow) unraveled and prolapsed into the IVC. It was then removed by a snaring catheter (white arrowhead) via transvenous route. b Two 40 mm × 60 cm Ruby framing coils were simultaneously deployed via transarterial and transvenous microcatheters to prevent coil migration (transarterial coil – white arrow; transvenus coil – white arrowhead). c Post-coiling angiogram showed improved parenchymal enhancement of right kidney but residual shunting into IVC along the AVF
