Hepatic vein reconstruction at inferior vena cava confluence using left renal vein graft.
OBJECTIVE
To preserve remnant liver function, extended left hepatectomy combined with middle hepatic vein reconstruction using a left renal vein graft was performed in resection of liver metastasis from sigmoid colon cancer, involving the confluence of the middle and left hepatic veins.


METHODS
The tumor, 5 cm in size, occupied the superior part of segment 4, and involved the confluence of the middle and the left hepatic veins. An extended left hepatectomy, including the left lobe, left caudate lobe and part of segment 8, together with the middle hepatic vein trunk, was performed. The left renal vein was resected as a graft from the confluence of the inferior vena cava just distal to the branches of the gonadal vein, renal-azygos, splenorenal communications and vertebral veins. The middle hepatic vein was reconstructed using the left renal vein 3 cm in length.


RESULTS
Impaired values of liver function tests were normalized by the third postoperative day. Renal function was good throughout the postoperative period. The patient was discharged two weeks after the surgery. The reconstructed middle hepatic vein was patent, which was evaluated by a color Doppler ultrasonography, computed tomography and magnetic resonance imaging 60 days after the surgery. The patient remained well in the eight months thereafter.


CONCLUSIONS
Hepatic vein reconstruction using a left renal vein graft is a new and preferable addition for the selection of an optimal graft.
