The following publication was reviewed: a case of delayed blood flow during viabahn implantation for bleeding from a pseudoaneurysm in the hepatic artery on an unknown date, a patient underwent a total gastrectomy, partial liver resection, partial transverse colectomy and cholecystectomy for residual gastric cancer.Ten days following the procedure the patient exhibited hypotensive shock.A ct showed a pseudoaneurysm at the origin of the left haptic artery.The hypotensive shock was deemed to be caused by bleeding from the pseudoaneurysm.It was decided the bleeding would be addressed endovascularly.First the middle hepatic artery was coiled to block the retrograde blood flow to the pseudoaneurysm.A gore® viabahn® endoprosthesis with heparin bioactive surface (6.0 x 25 mm) was then implanted from the proper hepatic artery to the right hepatic artery to exclude blood flow to the pseudoaneurysm.However, soon after the endoprosthesis was implanted, blood flow to the right hepatic artery disappeared.It was considered that thrombosis may be involved in the issue.Two metallic coronary artery stents were additionally implanted, and the issue was resolved.The article further stated that viabahn has an indication for traumatic or iatrogenic vessel injury with uncontrolled bleeding, however, often it is not possible to use antiplatelet drugs or heparin before the procedure when we use the device for hemostasis, and care must be taken with intraoperative thrombosis.In this case, the procedure was performed under non-administration of heparin, and ¿accordion phenomenon¿ caused by a guide wire was observed, it is considered that thrombus was easily formed.We should take countermeasures such as flushing the catheter frequently with saline.
