چکیده
PURPOSE Increasing use of implantable bars for minimally invasive pectus excavatum repair has introduced metal allergy (nickel and chromium) to pediatric surgeons. Metal allergy is a well-recognized entity in neurologic, orthopedic, and craniofacial surgery. This study was performed to evaluate metal allergy and its effects on treatment with the Nuss procedure in 862 patients. METHODS After institutional review board approval, we undertook a retrospective review of a prospectively gathered database of patients undergoing the Nuss procedure. Metal allergy was diagnosed either with the use of dermal patch or clinically, based on rash, fever, elevated erythrocyte sedimentation rate, cultures, and pathology specimens. Data collection included demographics, an allergy to jewelry, and history of atopy. Clinical outcomes including need for reoperation, removal of stainless steel bar, and replacement with titanium bar were evaluated. RESULTS Over an 18-year period (1987-2005), 862 patients underwent the Nuss procedure. Nineteen (2.2%) were diagnosed with metal allergy, with an average age of 14.7 years (9-23 years). Eighteen (95%) were males. A history of atopy was present in 9 (56%) patients. Ten (63%) patients presented with rash and erythema, 1 (6%) with granuloma, 5 (32%) with pleural effusion, and 3 (15%) were diagnosed on preoperative screening. Stainless steel bars were removed because of allergic skin breakdown in 3 patients, with 2 patients requiring replacement titanium bars. In all 3 of these patients, symptoms resolved after removal of stainless steel bars. Titanium bars were placed in the 3 patients who were diagnosed preoperatively with metal allergy, without event. CONCLUSIONS Allergy symptoms often are misdiagnosed as infection, but require different treatment. If a history of metal allergy or atopy is suggested preoperatively, the patient should be tested for metal allergy, and if positive, a titanium bar used. Because the consequences of metal allergy may include the need to replace the bar, pediatric surgeons should be aware of this occurrence.

Metal allergy to titanium bars after the Nuss procedure for pectus excavatum.
The Nuss procedure requires the placement of metal bars in the chest cage to repair pectus excavatum. Metal allergies are one of the complications associated with this procedure. Given that titanium is a biocompatible metal, it induces few allergic symptoms. Therefore, titanium bars are recommended for patients with metal sensitivity. We report the case of a 17-year-old boy with pectus excavatu...
متن کاملFirst Iranian Experience of the Minimally Invasive Nuss Procedure for Pectus Excavatum Repair: A Case Series and Literature Review
Pectus excavatum is the most common congenital deformity of the chest wall. The most frequently used techniques include Ravitch (costochondral resection) and Nuss (minimally invasive pectus repair of pectus excavatum [MIRPE]). The Nuss technique includes using temporary metallic bars without costochondral resection to correct the chest wall deformity. Modified MIRPE can be learned easily and pe...
