Portal vein reconstruction using an internal jugular vein as a graft: report of a case.

We report the case of a 41-year-old man with pancreatic carcinoma invading the portal vein who was successfully treated by portal vein resection combined with pancreatoduodenectomy and reconstruction using an autointernal jugular vein. The internal jugular vein is an ideal graft for portal vein replacement because it has sufficient length, a well-matched diameter, and there is no venous insufficiency after unilateral resection. Nevertheless, this is the first report of portal vein reconstruction using the internal jugular vein as a graft.
