Postoperative assessment of portal flow and dynamic CT image before (a, c, e) and after (b, d, f) splenic artery embolization. a Portal flow at the umbilical portion on postoperative day (POD) 9. b Portal flow on POD 11 at the same branch of the portal vein, which had decreased to half of that on POD 9. c Splenic arterial overflow with splenomegaly showed enhanced flow on injection of the contrast. Arrow, the main branch of the splenic artery. d The main branch of the splenic artery was completely occluded by trans-catheter coil embolization on POD 10. Arrow, the main branch of the splenic artery. e Dynamic computed tomography (CT) before splenic artery embolization showed only the upper pole of the spleen turns pale by the ligation. Arrow, paled lesion of the spleen. The lower pole has lost the arterial flow due to previous partial splenic artery embolization. f Dynamic CT after splenic artery embolization showed most of the spleen lost the arterial flow. Arrow, paled lesion of the spleen. POD, postoperative day; CT, computed tomography
