We used left renal vein (LRV) grafts for vascular reconstruction in patients with these malignancies and evaluated their clinical relevance.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A total of 113 patients underwent vascular resection including the PV (42 patients), IVC (68 patients), and HV (3 patients) for hepatobiliary\u2010pancreatic or abdominal tumor resection. Of these, 11 patients underwent vascular reconstruction with a LRV graft of the PV, superior mesenteric vein (SMV), and HVs in 3 patients each, and the IVC in 2 patients. The HVs were resected with segmentectomy involving Couinaud\u2019s segments VII, VIII, and IV; VII, VIII, and II; or III, IV, VIII in each patient. The PV and SMV were resected in 5 patients undergoing pancreaticoduodenectomy for pancreatic carcinoma, and in 1 patient being treated with extended right hepatectomy and pancreaticoduodenectomy for hepatic hilar carcinoma. The IVC was partially resected in 1 patient with advanced colon cancer and 1 with malignant schwannoma.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean graft length of LRV obtained was 3.6 (3.5\u20134.0) cm. The graft was used as a tube in 9 patients, and as a patch in 2 patients. The mean duration of clamping time was 41.9 (35\u201360) min. Portal vein thrombosis was encountered in 2 patients, and anastomotic stenosis in 1 patient. Other morbidity was not related to vascular reconstruction. One patient who underwent extended right hepatectomy and pancreaticoduodenectomy died of liver failure in the hospital. The serum creatinine level after surgery did not deteriorate except in the one patient who died in the hospital. Graft patency was maintained during the follow\u2010up period in all patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>A LRV graft may enhance the possibility of
