Treatment:
All our patients were managed with splenic artery embolization. Embolization in the first case was with coils. However, embolization in the second and third cases were done with Amplatzer plug and 500–700-micron PVA particles respectively. Our treatment methods were consistent with the modalities at other institutions. Many institutions have considered splenic artery coil embolization as the primary treatment for SASS (15,17). Patients with SASS often have a thick splenic artery with a diameter that is often thicker than 5.0 mm or 1.5 times that of the hepatic artery (14). Therefore, fast arterial flow can push the coil into the branch of splenic artery leading to ischemic necrosis of the spleen and possibly septicemia (10). Furthermore, the incidence of infection after coil embolization was reported to be as high as 50 % (15).
