The review performed by our quality assurance supervisor indicated that the graft was processed and inspected according to procedures and was therefore released following acceptable quality inspections and tests.Specifically, no anomaly was evidenced in the collagen coating records.The review of the water permeability testing records of products coated on the same day as the complaint device indicated values well within product specifications.Please note that water permeability testing is recognized by international standard for vascular grafts as the test to address the risk of blood leakage.A retention sample coated on the same period and under the same conditions as the involved device underwent water permeability testing.The testing was supervised by our quality assurance supervisor.The test result indicated a value well within product specifications (< 5 ml/cm²/min).In addition, the review of the post-marketing data indicated that no other similar complaint was reported to intervascular for the same product family and the same lot number.The involved product is being returned for investigation.A follow-up report will be sent to your attention upon completion of the investigation.Please note however that, as per the product instructions for use, the use of knitted vascular graft as a conduit for cannulation is not an approved indication.Indeed, hemagard knitted ultrathin vascular grafts are indicated for surgical repair, bypass, or replacement of arteries in the treatment of aneurysmal and occlusive disease of the visceral, renal and peripheral arteries.

Event Description
|
The patient underwent coronary arterial bypass surgery on (b)(6) 2016.Vascular bypass was used with internal mammary artery, signs of infarctus were observed.The patient was in intensive care unit, during the night she did not recover and developed left ventricular insufficiency.She was re-admitted in the morning to the operating room for placement of assist ecls (extracorporeal life support) with cardiohelp ecmo (extracorporeal membrane oxygenation).Cardiohelp was primed and connected to the left sub-clavial artery via insertion of the ecmo cannula in the involved graft.Cardiohelp went on flow of 2,5 lit/min.After some minutes, the graft started leaking in visible and dangerous way (jets).The surgeons decided to stop the ecls assistance by weaning of the cardiohelp in order to explant the graft.The patient did not support the weaning of the ecls mode : her heart went into fibrillation, another graft (from competition) was used to replace the involved graft, the ecmo procedure was restarted.The patient did not support the process and deceased.

The involved device was sent to an outside laboratory for macroscopic and scanning electron microscopy (sem) evaluation.The objective of the study was to evaluate the presence of any structural abnormality visible on the external side of the returned fragment and to evaluate the presence of collagen material.The sem analysis pointed out a heterogeneous collagen infiltration throughout the textile structure.No significant abnormality such as tears, loss of textile cohesion, holes or signs of cut were observed.The sem analysis corroborated the macroscopic analysis.No conclusion can be drawn.However, all available information and the product testing performed would tend to indicate that the device was not defective.
