(4111/3221 several e-mail attempts were sent to the initial reporter to obtain more information on the event in order to investigate and identify the root cause.No response was received from the initial reporter.(4112) the case description was reviewed by the medical affairs whose assessment is below: "this event is described as a hemagard patch used for a carotid artery surgical procedure.The report states that there was a clotting issue, however, it was not described in any detail.It is unknown if the clotting or lack of clotting (ie oozing or bleeding) occurred during or after the procedure was completed, and how the issue was resolved.There is no mention of if the patch remained implanted or if it needed to be replaced.There is no information on file regarding the patient¿s past medical history, including any coagulation disorder or medications taken.The coagulation parameters pre- and intra- operatively are also unknown.It is also unknown what anticoagulation therapy the patient received during the procedure.The disposition of the patient post-operatively is unknown as well as if there was any harm to the patient in this case.Because of the extremely limited information provided, the complaint of ¿clotting issue¿ itself is not well understood, and it is impossible to conclude if the issue was a result of the hemagard patch or due to other factors." (11) the investigation is still ongoing.A follow-up report will be sent upon completion of the investigation.

Event Description

Complaint (b)(4).

Manufacturer Narrative

Corrected data : on block h6 medical device - problem code: the code 3190 was updated to 3191, as the event information received does not permit to classify the event.And no information will be received to classify it.On block h6 health effect - clinical code : the code "4580" was updated to "1888" and "4440", due to the extremely limited information provided for the ¿clotting issue¿, it is not well understood, it is unknown if it is about clotting linked to an excessive coagulation or a lack of clotting linked to an oozing or bleeding.Therefore two codes were selected.Additional manufacturer narrative : (10/213) the involved device was returned to an external and independent laboratory for examination on (b)(6) 2022.A macroscopic analysis has been performed, it concluded that : "the macroscopic analysis of the patch does not reveal any macroscopic degradation on the pet structure.It would have been interesting to perform a permeability test on this segment however, the sample was already in contact with blood and might be too small to be tested in our laboratory".The macroscopic analysis report was sent to the medical department updates the medical review.Below the conclusion : "an independent laboratory analysis of the implanted/explanted hemagard vascular (carotid) patch did not reveal a degradation of the pet patch.It was not possible to perform a permeability study due to the presence of blood throughout the patch.No further conclusions can be made regarding the cause of the ¿clotting¿ issue in this incident." (4315) based on the medical review and on the investigation conclusion, it is impossible to conclude if the issue was a result of the hemagard patch or due to other factors because of the extremely limited information provided.Indeed the complaint of ¿clotting issue¿ itself is not well understood, it is unknown if it is about clotting linked to an excessive coagulation or a lack of clotting linked to an oozing or bleeding.No conclusion can be drawn on the exact origin of the adverse event due to the lack of information and the fact that the defect could not be reproduced/confirmed through the analysis of a retention sample.However, the conducted investigation suggests that the product was not defective at the time of manufacturing.
