# Microwave ablation and portal vein embolization for staged hepatectomy

## TL;DR

A modified surgical technique is used to safely perform liver resection in patients with liver damage and extensive tumors.

## Contribution

The AMAPS technique is introduced as a modified ALPPS procedure for patients with compromised liver function.

## Key findings

- AMAPS was successfully used in a patient with chemotherapy-induced liver injury and bilobar CRLM.
- The technique may reduce morbidity compared to classical ALPPS in compromised liver parenchyma.
- Microwave ablation combined with portal vein ligation enabled safe staged hepatectomy.

## Abstract

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.
