Abstract
The case involves a one-year-old male with a mesenchymal hamartoma involving the right hepatic lobe. The tumor-free segments comprised 17% of the liver volume, which placed the patient at risk for post-resection liver failure. A staged approach, the associating liver partition with portal vein ligation for staged hepatectomy, was employed. This allowed the interval growth of the liver remnant and thereafter enabled right lobectomy with adequate liver function.
