Partial embolization as re-treatment of hypersplenism after unsuccessful splenic artery ligation

Figure 1 Imaging studies. A: After ligation of splenic artery treatment, abdominal computed tomography showed that the size of the spleen was enlarged (white star). Ischemic necrosis was not seen in the spleen. However, the bio-clamp (white arrow) was seen in the splenic artery area; B and C: Splenic compensatory arteries: the dorsal pancreatic artery (green arrow), and the left gastro-epiploic artery (red arrow). CTA: Computed tomography angiogram; DSA: Digital subtraction angiography.

Figure 2 Partial splenic embolization therapy. A: Partial splenic embolization (PSE) therapy through the collateral artery of dorsal pancreatic artery; B: PSE therapy through the left gastro-epiploic artery; C: Abdominal computed tomography (CT) revealed that ischemic infarction (black arrow) was seen in the spleen 2 wk after PSE; D-F: Follow-up abdominal CT was performed after 4 mo (D) and 9 mo (E and F), showing that the size of the spleen and infarction (black arrows) progressively decreased.
