Event Description

The following information was reported to gore: on an unknown date, the patient was implanted with a gore® propaten® vascular graft (propaten vascular graft) as a venous-venous shunt for hemodialysis.The procedure date and the device information is unknown.One or two days post implantation, wound exudate was observed from the incision site approximately 1 mm away from the device.Frequent anastomotic stenosis occurred though it was unclear whether the stenosis was caused by the exudate.On february 7, 2024, the patient underwent an endovascular treatment for the anastomotic stenosis using gore® viabahn® endoprosthesis with heparin bioactive surface (viabahn device).Blood culture test was negative before the procedure.The viabahn device was implanted to repair the stenosis and the wound exudate.The viabahn device was implanted in a site with observed exudate.Symptomatic improvement was observed immediately after implantation.On (b)(6) 2024, purulent drainage was observed.It was confirmed infection at the site of the viabahn device.On (b)(6) 2024, a reintervention was performed and both propaten vascular graft and viabahn device were removed from the patient.Reportedly, there was a risk of infection since the patient had symptoms of exudate.The physician commented that the device placement to the exudate site may have been a mistake.
