Hypersplenism treated by partial splenic embolization using guglielmi detachable coils

A 52-year-old man underwent partial splenic embolization (PSE) for hypersplenism. The intrasplenic artery targeted for the embolization was large, and the distance between its trifurcated branches was short; therefore, Guglielmi detachable coils (GDC) 360° Complex Shape® were used, as well as conventional metal coils, to prevent coil migration. GDC are equipped with a shape-memory function and are more physically stable than conventional metallic coils because they form three-dimensional loops. In this case, an ideal extent of the splenic infarction was successfully achieved using a small number of coils. This is the first report of the use of GDC in PSE for hypersplenism.
