Abstract
Post-pancreaticoduodenectomy hemorrhage is a life-threatening complication that usually occurs in skeletonized arteries. Venous hemorrhage is a rarer complication, and surgical management is often challenging. We herein report the case of an 80-year-old man who suffered from prolonged pancreatic fistula and long-term drainage tube placement, which could cause late post-pancreaticoduodenectomy hemorrhage from the confluence of the splenic and extrahepatic portal veins. An intrahepatic posterior portal venous branch was percutaneously punctured, and the splenic vein was embolized using coils and a vascular plug. A balloon-expandable covered stent was also placed from the superior mesenteric vein to the main portal vein to cover the confluence, which required a system as small as 8-F. Portal venography revealed good patency without extravasation. Thereafter, antithrombotic and antibacterial treatments were successfully administered without any additional interventions. He remained well without any evidence of thrombosis or indolent infection 19 months after endovascular treatment. The endovascular coil and cover technique with prolonged adjuvant therapy is a feasible alternative for managing such critical situations.
