Manufacturer Narrative

Manufacturer's investigation conclusion: the report of foreign matter near the anastomotic site of the graft could not be confirmed.The material was reportedly observed via echo on the venous side of the artificial blood vessel.There was no trace of puncture near the site.Removal of the material was considered before it was decided to cover the material with a stent.It was indicated that there was no thrombus and no adverse impact to the patient as a result of the issue.Review of the device history records showed no deviations from manufacturing or qa specifications, including visual and dimensional inspection.Graft preparation and implantation are addressed in the vectra vascular access graft (vag) instructions for use (ifu).Occlusion, stenosis, and thrombosis are listed as potential complications with the use of a vascular prosthesis.Intragraft obstruction is listed as a potential complication in table 2 in the summary of vectra vag clinical experience section of the ifu.The ifu states that the graft should not be pulled (axially elongated) or stretched during handling at implantation.The graft should be trimmed long enough to prevent stress on the anastomosis and allow for a full range of body motion when implanted.Excessive elongation or stretching of the graft will damage the microporous layers of the graft.No further information was provided.The manufacturer is closing the file on this event.
