Background/Aims:
Resection of hepatic arteries is often obligatory on resecting pancreatic, gastric and hepatobiliary malignancies. Hepatic artery reconstruction is required to preserve liver function and blood flow to the bile duct. We applied the gonadal vein to hepatic artery reconstruction.
Methodology:
Hepatic artery reconstruction using a gonadal vein graft was performed in two patients: one with gallbladder cancer and the other with recurrent gastric cancer.
Results:
The right ovarian vein, 2 mm in diameter and 4 cm in length, was grafted for reconstruction between the proper hepatic and the posterior hepatic artery in one patient who underwent modified central hepatic bisegmetectomy and common bile duct resection. The left spermatic vein, 3 mm in diameter and 6 cm in length, was grafted for reconstruction between the celiac artery and the right hepatic artery in the other, who underwent upper abdominal exenteration. The former graft was occluded due to tumor invasion at 4 months after surgery, the latter one was patent at 8 weeks after surgery.
Conclusions:
The gonadal vein had an ideal diameter and sufficient length to accomplish hepatic arterial reconstruction. The gonadal vein graft will be a new and preferable addition to the selection of an optimal graft for hepatic arterial reconstruction.
