Loop Cautery for Chronic Lymphangioma Removal

Supplemental video for Seervai R.N.H. et al. (2025), Loop Cautery for Chronic Lymphangioma Removal, JAAD Case Reports. Videographic demonstration of loop cautery for lymphangioma removal. The areas for treatment are prepped with an alcohol wipe (not shown), and local anesthesia is obtained with injection of 1% lidocaine with 1:100,000 epinephrine. The lymphangiomas are removed with loop cautery, and a smoke evacuator is used to minimize smoke/fumes from the procedure. Minor bleeding is stopped with electrocoagulation. The authors thank Christopher Garvey (@siskietrax) for assistance with filming and producing this video.本视频为Seervai R.N.H.等人2025年发表于《JAAD病例报告》（JAAD Case Reports）的《环形电灼术（Loop Cautery）切除慢性淋巴管瘤（Chronic Lymphangioma）》一文的补充视频。 本视频演示了环形电灼术切除淋巴管瘤的操作流程：治疗区域先用酒精棉片（alcohol wipe）消毒（视频中未展示该步骤），随后注射含1:100000肾上腺素（epinephrine）的1%利多卡因（lidocaine）实施局部麻醉（local anesthesia）。术者采用环形电灼术切除淋巴管瘤，并使用烟雾抽吸装置（smoke evacuator）以减少手术过程中产生的烟雾与废气。少量出血则通过电凝术（electrocoagulation）进行止血。 作者感谢Christopher Garvey（账号@siskietrax）为本视频的拍摄与制作提供协助。
