Patient had an allergic reaction.The graft was sutured in with a 5-0 prolene on a c-1 needle.The customer requested a small sample to attempt to pin down the allergy source.The surgeon reported to the cook area representative that the patient came back with a suspected tumor recurrence.The patient was reoperated on and there was not a tumor present, but rather what appeared to be an allergic reaction.The area cleaned up and the samples were sent for testing.The results did not indicate the reaction was to biodesign.The surgeon uses biodesign often and has no concerns.On 06/29/2021, dr.(b)(6) reported additional details to cbi.The patient's underlying condition being treated was a meningioma.The biodesign dural graft was implanted as a replacement of the dura that was removed as part of the tumor resection.The graft was fixed into place with prolene suture.There was no concurrent medications at the time of graft placement or new medications post-op.There were also no ointments, creams or special wound care bandages used on the patient.The patient underwent a repeat craniotomy for resection of the graft.The patient's course of events was determined to be a granulomatous reaction to foreign body.This was determined by a nodular contrast-enhancement on mri, granulomatous inflammation on pathology, negative acid bacilli and grocott methenamine silver stains, and cd68 highlights histiocytic infiltrate.
