Abstract

Pancreatic cancer is often advanced and invades the major blood vessels around the pancreas. Portal vein (PV) and/or superior mesenteric vein (SMV) resection is performed for radical resection. In such cases, end-to-end anastomosis is best if the remnant vein is sufficiently long. However, when the excision distance is long, reconstruction requires an artificial blood vessel. In contrast, there is no consensus concerning the need for splenic vein (SV) reconstruction. We herein report a case in which portal vein thrombus and congestion of the bowel that occurred after PV-SMV reconstruction were improved by additional anastomosis of the PV-SV.

Keywords: artificial blood vessel; eptfe; pancreatic head cancer; portal vein resection; splenic vein.
