Splenic artery steal syndrome due to lowered splenic arteriolar resistance, enlarged splenic artery, and splenomegaly causes ischemia and failure in transplanted livers. Traditional treatments include surgical splenectomy, splenic artery ligation, and reanastomosis of the hepatic artery graft with an interposed vascular graft from the aorta. However, these treatments are associated with several potential perioperative and postoperative complications. Percutaneous interventional methods, such as splenic artery embolization with coils or placement of a narrowed stent into the splenic artery, are alternatives to surgery for treating splenic artery steal syndrome. Splenic artery embolization may cause postembolization syndrome. Narrowed stent placement into the splenic artery is a new technique for treatment of this syndrome. Narrowed stent placement into the splenic artery was performed in 5 patients (all men; age range, 17-47 years) with splenic artery steal syndrome after orthotopic (3 patients) or heterotopic liver transplantation (2 patients). The narrowed stent was placed in the middle of the splenic artery. Follow-up revealed that splenic artery steal syndrome was treated successfully with the narrowed stent placement in the splenic artery in all 5 liver transplant recipients. Placement of the narrowed stents was associated with lower frequencies of postintervention fever and pain, shorter hospital stay, and less need for antibiotics. Percutaneous placement of a narrowed stent in the splenic artery is a promising new technique for treatment of splenic artery steal syndrome.
