[Interventional and vascular surgical management for inflammatory arrosion hemorrhage from visceral arteries following pancreatic surgery]

Abstract

Spontaneous or postoperative hemorrhage into the abdominal cavity due to inflammatory vessel arrosion represents an uncommon but menacing situation. According to the literature, such hemorrhage is associated with a lethality of nearly 2%. Therapeutical options include reoperation and interventional radiological techniques such as endovascular catheter techniques with stent graft implantation or the embolization of vessels. We report on the management of seven cases with hemorrhage either from the gastroduodenal artery ( n=5) following pancreatic surgery for pancreatic carcinoma, liposarcoma, and chronic pancreatitis or from the common hepatic artery ( n=1) and the superior mesenteric artery ( n=1) following chronic pancreatitis. The present article describes our experiences with stent graft implantation (hemobahn prosthesis) in four cases. Based on these experiences, we see the advantages of stent grafts in primary hemostasis without any contact to infected tissue and the preservation of regular perfusion. However, further clinical data are required focussing on indication, technical success rates, stent-related complications, and long-term outcome.
