Abstract
Silver-coated grafts are designed to prevent vascular graft infections. Silver is a safe element but toxic effects have been reported. We describe two cases of possible localized argyria after silver graft implantation. Two patients presented with perigraft groin collections after implantation of silver grafts. During reoperation, an ashen-grey necrotic substance was seen surrounding the grafts. The grafts were explanted and lower limb perfusion restored. Cultures were negative and both patients had uneventful recoveries. Our cases are highly suggestive of a possible unique adverse effect: a combination of localized silver toxicity and neutrophilic mediated tissue destruction.
