Event Description

It was reported to gore that the patient underwent surgical treatment for a critical limb ischemia with a gore® propaten® vascular graft ¿ thin-walled removable ringed.It was stated that a vascular graft (sn (b)(6)) was implanted on (b)(6) 2023, as a femoro-popliteal bypass to treat a critical limb ischemia.Later the proximal anastomosis obliterated, therefore, on (b)(6) 2023, a further gore® propaten® vascular graft ((b)(6)) was implanted.During this procedure bacteria have been introduced and wound dehiscence due to infection was diagnosed (b)(6) 2023.The patient has presented with fever, dehiscence of the bypass scar with a serous secretion and inflammatory syndrome, requiring hospitalization.Imaging confirmed infection of the grafts.Samples taken were positive to staphylococcus epidermis, corynebacterium tuberculostearicum and staphylococcus aureus.The anastomoses were stenosed and the graft was thrombosed due to persistent infection.Therefore, on (b)(6) 2023, both devices were explanted and were replaced with an allograft.The patient recovered without sequelae and was discharged home on (b)(6) 2023.There was no preexisting infection and the physician stated that the infection was related to the implant procedure of propaten ((b)(6)).

Manufacturer Narrative

Explant evaluation: the graft fragment was returned to gepromed for investigation.Submitted in formalin was a gore® propaten® vascular graft ¿ thin-walled removable ringed fragment.The scope and results of the investigation were summarized, and a report was submitted to w.L.Gore & associates.An explant scientist at w.L.Gore & associates reviewed the report.The graft fragment was reported to measure 370 mm in length, and both ends were transected.The abluminal surface appeared to be stained light tan to dark brown, and the blue alignment marks were faintly visible.The rings appeared to be displaced at the mid-body of the graft fragment.The lumens at extremity a and b of the fragment appeared to be open.Extremity a and extremity b both appeared to be partially flattened, transected, and removable rings were absent in these areas.Extremity b appeared to have a jagged edge.A blue monofilament was present at extremity b.No saline patency test was noted to have been performed, therefore the patency of the graft fragment could not be confirmed based on the analysis or images provided.Material disruptions (e.G., transections) were consistent with those caused by surgical instrumentation (e.G., scalpel, scissors), likely used during a surgical procedure.Based on the explant scientist¿s review of the gepromed report, no additional analysis is requested.No information was provided to confirm the presence or absence of the reported infection and no determination can be made from the provided information.In the instruction for use for the gore® propaten® vascular graft the following is stated: adverse events: potential device or procedure-related adverse events.Complications which may occur in conjunction with the use of any vascular prosthesis and/or vascular or related procedures include but are not limited to: infection.
