Additional Manufacturer Narrative
We have received a non-implanted piece of the graft for evaluation and we have confirmed the reported incident.When the graft was pressurized, we observed a region on the suture tie to be aneurysmal.However, the aneurysm at this region did not appear to be as a result of cellular degeneration but rather appeared as a way this side branch was ligated.When we pressurized the graft to 5 psi ( 258 mmhg ), we did not observe any leakage and the graft remained patent.Based on our device evaluation, we do not consider this defect to be significant that can result in serious injury to the patient.Procol 'vacular' bioprosthesis is derived from a single length of bovine mesenteric vein that is chemically cross-linked with glutaraldehyde.Natural variations even in the same graft is possible.Collateral branches are ligated with surgical suture and the graft is inspected under pulsatile flow conditions at simulated physiological internal graft pressure.Each graft is pressurized between 2.7-4.0 psi ( 139 - 206 mmhg) during the inspection process.If pressure exceeds 4 psi, the vessel is rejected for 'overpressurized' and discarded.Under a pressurized condition, each graft is inspected by the manufacturing operators for any presence of hole, tear or swelling.An od gage is passed over the entire length of the vessel.If any section of the graft appeared to be swollen or did not pass through the gage smoothly, then that section of the graft is rejected by the technician.Each graft is again inspected by the qc technician for these attributes.We have conducted a lot history review and did not find any issues noted in the manufacturing or packaging process that could be related to this issue.All qc tests passed their requirements.
Event or Problem Description
Surgeon used a procol vascular bioprosthesis for creating a bridge graft for vascular access to a dialysis patient.After surgeon completed the arterial anastomosis, upon pressurizing the graft, he observed aneurysmal spot at three different suture ties in the graft.
