Transcatheter coil embolization of an aneurysm of an anomalous splenic artery: usefulness of double microcatheter method.

Transcatheter embolization using two microcatheters of different shapes was performed to treat a 34-mm-diameter aneurysm that was located near the origin of a splenic artery that originated from the superior mesenteric artery (SMA). The procedure resulted in complete packing of the aneurysm and preserving splenic arterial blood flow.
