Right-sided ALPPS after preoperative emergency embolization of the right hepatic artery: case report with a favorable anatomy.

In patients with extensive colorectal liver metastases (CRLM) and insufficient future liver remnant (FLR) a faster and more effective FLR augmentation than portal vein embolization is the associating liver partition and portal vein ligation in staged hepatectomy (ALPPS). Before ALPPS, the presence of arterial blood supply to the subsequently resected hemiliver must be ensured. We present a case with neoadjuvant-treated CRLM and insufficient FLR who developed a large intrahepatic hematoma after liver biopsy. For continuous bleeding, the right hepatic artery was embolized. Fortunately, an accessory right hepatic artery arising from the superior mesenteric artery was present, which enabled the ALPPS procedure to be performed. After ALPPS, the patient did not experience liver failure. The case exemplifies that preoperative evaluation of the vascular supply of the liver is of paramount importance in advanced hepatic surgery such as ALPPS.
