In a review of published literature, the following findings were noted: yasuhiro fujiwara et al., ¿a case of bleeding of cha pseudoaneurysm developed after pd which was treated by a viabahn¿ in ivr: interventional radiology, volume 32, number 4, page 331 (january, 2018).This patient was male and was in his eighties.The patient underwent a pancreaticoduodenectomy (pd) and a segmentectomy of s4 (medial segment) of the liver as the patient had a duodenal cancer with liver metastasis (s4).Postoperative day 6, biliary fistula developed and a percutaneous transhepatic biliary drainage (ptbd) was performed.Pancreatic fistula was also suspected.Postoperative day 17, bleeding from a drain tube was observed.Angiography showed bleeding from a pseudoaneurysm of the common hepatic artery (cha).On (b)(6) 2017, it was elected to use a gore® viabahn® endoprosthesis with heparin bioactive surface for hemostasis.Angiography also showed a stenosis of the proper hepatic artery (pha).As it was impossible to deliver the endoprosthesis to the stenosis of the pha, the endoprosthesis was implanted at the pseudoaneurysm of the cha and hemostasis was achieved.However, the endoprosthesis was occluded after the implantation.It was reported that spasm might have caused the occlusion, but definitive cause was unknown.As blood flow from the superficial femoral artery into the liver was confirmed, no treatment was performed for the occlusion.The procedure was concluded.On (b)(6) 2017 (6th day after the procedure), liver abscess developed, and drainage was performed.No further information was available.
