A "blood theft" after liver transplantation: the role of interventional radiology in the management and treatment of splenic artery steal syndrome

Splenic artery steal syndrome is a rare complication after liver transplant. It could lead to rapidly evolving major issues such as ischemic cholangiopathy and acute graft failure. Although the pathophysiology is not yet well understood, if diagnosed in time it could be easily managed with interventional radiology treatments. We present a case of a 47-year-old man presented to our institute with radiological findings typical for multifocal hepatocellular carcinoma in a cirrhotic liver. After therapy he underwent transplant. Some days after surgery he developed signs of acute liver failure. Steal syndrome was suspected by laboratory tests and radiology exams. The syndrome was confirmed by angiography and treated. The graft was saved, and the patient is still alive and free of disease. The purpose of this paper is to explain the importance of radiology exams in the diagnosis of splenic steal syndrome, explain its pathogenesis and describe the interventional management of this complication.
