Metallic allergy requiring removal of iliac stent: report of a case

Background The use of metallic stents, which are predominantly composed of nickel, in the treatment of patients with nickel allergy has not been well studied. Case presentation A patient who suffered from contact dermatitis due to implantation of an iliac stent was successfully treated by removing the stent that caused nickel allergy. The patient has exhibited no symptoms of claudication or severe pruritic rash in the 2-year follow-up period after iliac stent removal. Conclusions We herein report a case of nickel allergy in which a metallic iliac stent that was predominantly composed of nickel was removed. The patient showed a marked recovery from her contact dermatitis. In cases of suspected metallic allergy, it is necessary to consider revascularization without using a metal device.
