Pad burns during or after radiofrequency ablation (RFA) are a skin complication probably underreported in the literature. We report on 4 severe pad burns, deep second and third degree, in 3 patients undergoing radiofrequency ablation of liver malignancies, 1 percutaneously and the other 2 after laparotomy. All burns occurred at the leading edge or at the corner of the pads attached to the patients' thighs. Potential causes leading to the burns are discussed. Current dispersive pad designs do not prevent the leading edge phenomenon and subsequent burns. Further developmental work in the pad design with the possibility of skin temperature monitoring via temperature sensors under the leading pad edge is needed.
射频消融术(RFA)期间或之后发生的极板烧伤是一种皮肤并发症,可能在文献中报道不足。我们报告了3例接受肝脏恶性肿瘤射频消融术的患者发生的4例严重极板烧伤,为深二度和三度烧伤,其中1例为经皮消融,另外2例为剖腹术后消融。所有烧伤均发生在连接患者大腿的极板前缘或角落处。文中讨论了导致烧伤的潜在原因。目前的分散式极板设计无法防止前缘现象及随后的烧伤。需要在极板设计方面做进一步的研发工作,通过在极板前缘下方设置温度传感器来监测皮肤温度。
