Laser ablation for varicose veins is a common practice, and postoperative complications may happen. A retained foreign body could be left accidently in the treated leg. It is rarely reported in literature. We herein describe two cases of retained foreign body during the laser ablation for varicose veins. One patient with varicose veins received laser therapy 5 years earlier, and had experienced discomfort and pain. After investigation, an overlooked sheath fragment was removed surgically from the leg. Another patient with varicose veins had discomfort after laser ablation for 8 days, and has been asymptomatic after the removal of the retained foreign body in the leg. The essential preventive approach include to pinpoint the site of the tip of fiberoptic laser fiber and pull 1 to 2 cm of the sheath out of the patient, then withdrawal the fiberoptic fiber and sheath simultaneously. A white flash light in the trunk of the fiberoptic laser fiber is an important warning signal of an erroneous manipulation during the operation. The surgeon should routinely check the intact sheath and fiberoptic fiber after laser ablation. In conclusion, retained foreign body can be prevented by following some practical tips during laser ablation.
激光消融治疗静脉曲张是一种常见的治疗方法，术后可能会发生并发症。治疗过程中可能会意外遗留异物在治疗的腿部。文献中对此鲜有报道。我们在此描述两例静脉曲张激光消融术中遗留异物的病例。一名静脉曲张患者5年前接受了激光治疗，之后一直感到不适和疼痛。经检查，从腿部手术取出了一个被遗漏的鞘管碎片。另一名静脉曲张患者在激光消融术后8天出现不适，取出腿部遗留异物后症状消失。重要的预防措施包括确定光纤激光纤维尖端的位置，将鞘管拔出患者体外1至2厘米，然后同时拔出光纤和鞘管。光纤激光纤维主干出现白色闪光是手术操作错误的重要警示信号。外科医生在激光消融术后应常规检查鞘管和光纤是否完整。总之，在激光消融过程中遵循一些实用技巧可以预防异物遗留。
