多種類の金属アレルギー患者に対する僧帽弁形成術の1例

Mitral Valve Plasty in a Patient with Multiple Metal Allergy；Report of a Case

はじめに　人工臓器の構成成分に対してアレルギー反応を起こし，問題となる症例が報告されるようになっている．われわれは多種類の金属アレルギー患者に対して，金属を含まない人工弁輪を用いた僧帽弁形成術を施行し，良好な結果を得たので報告する．

A 76-year-old woman was admitted to our hospital complaining of dyspnea on effort. Echocardiography showed severe mitral regurgitation. Her medical history indicated that she was allergic to metal, and skin patch tests were positive for nickel, cobalt, platinum, manganese, iridium, chromium, and zinc. Valvuloplasty involved triangular resection of P2 and mitral valve annuloplasty with a metal-free, 29 mm Tailor Flexible Ring. The sternum was closed using polyester non-absorbable sutures instead of surgical steel wire. Her postoperative course was uneventful and she was discharged on postoperative day 21. Nine months later, she is well and free of allergic symptoms.
