To the Editor,

Recently, large volume detachable coils such as Ruby coils (Penumbra, Alameda, California) have become available for use in peripheral intervention and presents as an alternative to conventional embolization techniques. We describe a case of coil migration during embolization of an aneurysmatic renal arterio-venous malformation (AVM) and describe our salvage technique.

A 60-year-old woman was presented with right flank pain for 5–7 months duration, and a 33 × 32 × 29 mm hypervascular lesion was found in the right renal hilum on CT (Fig.  1). Time-resolved MR angiography showed the lesion to be the aneurysm sac related to a renal AVM (Movie 1), and she was referred for embolization.

Supplementary material

MOVIE 1: Time resolved contrast enhanced MR angiography showed the lesion to be a saccular aneurysm with arterial supply and early venous drainage (note the early enhancement of the right renal vein), consistent with an arterio-venous malformation. (AVI 520 kb)

MOVIE 2: Right renal angiography showing prompt opacification of the aneurysm sac with early venous drainage, consistent with an arterio-venous malformation. (AVI 196 kb)

MOVIE 3: Captured coil being pushed into the center core of the coil complex. (AVI 2561 kb)

MOVIE 4: Captured coil being pushed and repositioned around the periphery of the coil complex and successfully released. (AVI 2717 kb)

MOVIE 5: Completion renal arteriography. (AVI 311 kb)

MOVIE 6: Follow-up angiography at 6 months. (AVI 300 kb)
