伴或不伴有临床甲状腺机能亢进的自主性孤立甲状腺结节(Plummer’s结节)的标准治疗方法是外科或放射碘治疗。但这两种方法都有欠缺,比如价格昂贵。在声谱仪引导下经皮乙醇注射疗法(PEI)以其安全、价廉而受到普遍接受。PEI 已成功地用于治疗高功能性甲状旁腺结节。初步的资料认为该方法可用于伴有自主功能的孤立甲状腺结节。 The standard treatment for an isolated, isolated thyroid nodule (Plummer’s nodule) with or without clinical hyperthyroidism is surgical or radioiodine therapy. However, these two methods are lacking, such as expensive. Under the guidance of sonography, percutaneous ethanol injection (PEI) is generally accepted for its safety and low cost. PEI has been successfully used to treat highly functional parathyroid nodules. Preliminary data suggest that the method can be used with isolated thyroid nodules with autonomic function.
