Comparison of total splenic artery embolization and partial splenic embolization for hypersplenism

Figure 2 Computed tomographic angiography, arterial phases, before and after splenic artery embolization in the same patient as Figure 1. A: Before embolization the spleen is enlarged; B: One month after embolization the major portion of the spleen is avascular with minute areas of low attenuation representing residual gas collection. A small part of the spleen was perfused with contrast medium; C: Six months after embolization the low attenuation area has decreased in size; D: One year later the low attenuation area has further decreased in size; E: Two years later the necrotic area has further decreased in size; F: Four years later no significant change is seen.
