Objective To explore the clinical application of in vivo hepatectomy with preservation of retrohepatic inferior vena cava (IVC) for hepatic alveolar echinococcosis (HAE) with the invasion of IVC. Methods The clinicopathologic data of a complicated HAE patient with large lesion (maximum cross-section 12.6 cm×9.6 cm), infiltrative growth, unclear boundary with surrounding tissues, and invasions of diaphragm and IVC (invasion length up to 4.6 cm) admitted to the Department of Liver Surgery in the West China Hospital of Sichuan University in December 2021 was retrospectively collected. The three-dimensional reconstruction of the liver model was performed by Mimics Medical 21.0 software before operation. The invading IVC of the right liver lesion was measured and the resection was simulated. During the operation, the HAE lesion and the affected IVC were gradually separated from IVC by the hemostatic forceps, and the residual lesions were gradually removed. Results In this patient, the HAE lesion of right liver was resected, the IVC was entirely preserved, and the resection of liver was consistent with the preoperative three-dimensional reconstruction plan. The operation time was 275 min, the bleeding was approximately 500 mL. On the first day after the operation, the alanine aminotransferase and aspartate aminotransferase were increased, no obvious abnormalities were observed in the plasma albumin and bilirubin, the patient recovered and was discharged on the seventh day after the operation. No complications occurred after the operation, and no recurrence or metastasis of HAE was observed during follow-up period. Conclusions Hepatectomy with preservation of retrohepatic IVC for HAE with invasion of IVC is safe and effective. Taking albendazole regularly after surgery will help maintain disease-free survival.
