The graft was not received for evaluation since it remains implanted.Hence, we could not conclusively determine the cause of the failure.Patient information and status were requested but information was not received, to date.Thrombosis is a known possible issue.The instructions for use, adverse reactions section lists thrombosis as a complication.Possible root cause may be low blood flow, inadvertent external compression (e.G., from clothing, etc.), inadequate heparin therapy for the patient, graft rotation/ implantation technique, or the graft may have been used in low pressure system.All grafts released from batch 21h219 met the requirements for release, including pressure testing, sterility testing, and final visual inspection prior to release to finished goods.To date, no additional complaints were reported from this product batch.Based on our investigation this appears to be an isolated incident.All product quality and clinical issues will continue to be monitored within quality assurance trending.
