The liver is subject to transplantation as part of the treatment for neoplastic lesions and liver failure. Patients may develop ischemic lesions following this surgical procedure, which should be differentiated from other categories of focal liver lesions, particularly tumor recurrence and infection. In this presentation, we aim to discuss the main imaging findings and the pathophysiology of each kind of hepatic ischemic injury, following liver transplantation.

- A quick review on the most common liver conditions that require transplantation (focus on cirrhosis and HCC). - Anatomical description and schematic drawings of the most common surgical procedures of the liver transplantation. - Imaging findings of the normal postoperative liver, based on MDCT, angioCT and MRI. - Main imaging findings from hepatic ischemic injury liver transplantation procedure: Arterial (obstruction, stenosis, extrinsic compression, pseudoaneurysm and fistula); Portal (including portal vein, inferior vena cava and hepatic veins stenosis and thrombosis); secondary to hypovolemia; reperfusion lesions.
