Manufacturer narrative: clinical code: 4582 - health effect - no clinical sign's, symptoms or conditions , no clinical sequelae.Impact code: 4632 - prolonged surgery - the 8mm graft that was used was removed and replaced with a 10 mm graft.Medical device problem: 3190 - insufficient information- reported as leakage.Component code: 4755 - part/component/sub-assembly term not applicable.Type of investigation: 4110 - trend analysis: a 5-year review of similar complaints (leakage > other jan 19 - jan 24 v gelweave sales jan 19 - jan 24 ) gave an occurrence rate of (b)(4).4111 - communication interview: additional information from has been requested from the site.3331 - analysis of production records: full batch review performed which showed no issues with the device during manufacture from raw material to finished products.10 - testing of actual device, device is being returned for analysis.Investigation findings: 213 - no device problem found - analysis of the returned graft was performed on 07 mar 24 , no issues could be found with the device on further investigation.The returned section of graft was heavily contaminated with blood.From the images supplied by the surgeon the blood leakage looks like it is at the distal end of the graft from the cannula and that the proximal end was blood tight (see image 1 above).The textile analysis shows that the physical characteristics of the base fabric of the graft were within specification which rules out the base fabric as being the root cause of this failure.The other potential root cause is inadequate coverage of gelatin along the length of the graft, unfortunately we could not carry out gelatin analysis because of the presence of large amounts of blood on the graft.However, all gelatin sealed grafts undergo leakage testing during manufacture.This graft passed this test which confirms that the gelatin coverage was sufficient to prevent excessive leakage from the full length of the graft during this test.Investigation conclusion: 67 - no problem detected - as this graft was replaced and the leakage was on going the root cause was deemed to be not device related.Additional information : section h1 - additional information was received to say patient passed away, cause was family withdrawal of care due to prolonged care without meaningful recovery, he was 83.Indirectly bleeding from the graft did prolong the care and significantly change the course.
