Microwave ablation and portal vein embolization for staged hepatectomy

Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) enables resection of extensive colorectal liver metastases (CRLM) by inducing rapid hypertrophy of the future liver remnant (FLR). However, the classical approach is often associated with significant morbidity, particularly in patients with compromised liver parenchyma. We present a case utilizing the associating microwave ablation and portal vein ligation for staged hepatectomy (AMAPS) technique as a modified ALPPS procedure in a patient with chemotherapy-induced liver injury and bilobar CRLM.
