ABSTRACT
BACKGROUND:
Hepatic vein reconstruction (HVR) is occasionally necessary for resecting hepatic malignancies to ensure surgical margins while preserving remnant liver function [1]. Reports of multiple HVR are rare due to the highly technical demanding procedure and high risk of morbidity [2]. We introduce our procedure of double HVR for metastatic liver tumors invading the right hepatic vein (RHV) and middle hepatic vein (MHV).METHODS:
The patient was a 66-year-old man with colorectal liver metastasis in segment 8, invading RHV and MHV. Due to impaired liver function, extended right hemihepatectomy was unsuitable. Thus, extended anatomical resection of segment 8 with double HVR was performed. The liver was completely mobilized and the RHV and MHV were secured. After liver parenchyma dissection, the specimen was connected by RHV and MHV (Fig. 1). The MHV was dissected and reconstructed using a right superficial femoral vein graft while the RHV remained connected [3]. Reconstruction of the MHV was performed on the posterior wall of the proximal side, followed by the anterior wall, using 4-point supporting threads. Anastomosis was performed by the over-and-over suture method. On the distal side, two-point supporting threads were applied. After specimen removal, the RHV was resected and reconstructed in the same manner using a left internal jugular vein graft [4].RESULTS:
The patient was discharged on postoperative day 14 with no signs of liver failure. Computed tomography performed six months after surgery revealed no graft occlusion (Fig. 2).CONCLUSION:
In appropriately selected patients, this technique may be a useful option for preserving the remnant liver function.Palavras-chave
