A 35-year-old male with sick sinus syndrome was complicated with recurrent local infection at the site of the generator pocket associate with a retained pacemaker lead, followed by septicemia presenting with Staphylococcus aureus. Several attempts to remove the lead via the implantation vein by direct traction were performed unsuccessfully because the leads were strongly adhered to the trabecula of the right ventricle. Repeated debridement employing antibiotic therapy was ineffective. As a last resort, we finally operated under extracorporeal circulation (ECC) 24 months after the first implantation and 22 months after initiation of the local infectious episode. As we found it difficult to remove the leads by traction even under direct vision, we used the vinyl chloride tube, which is a part of the ECC circuit, as a sheath for applying countertraction around the lead tip to prevent the myocardial wall from being torn and extracted together with the lead tip. The lead was removed successfully and a new epicardial lead was implanted. The postoperative course uneventful and no recurrence has occurred after 1 year. In reviewing the Japanese literature, 10 case, operated on under ECC to remove the infected retained leads, were described in detail. Among them, eight cases had undergone previous debridement including removal of the generator and the subcutaneous portion of the lead. It is clear that removal of all of the pacemaker system is necessary for eradication of infection. Adhesion of the lead to the wall is firm. Only one case besides ours succeeded in having its lead removed without requiring incision of the tissue around the lead tip.(ABSTRACT TRUNCATED AT 250 WORDS)
一名35岁患有病态窦房结综合征的男性,其起搏器囊袋部位因保留的起搏器导线反复发生局部感染,随后出现金黄色葡萄球菌败血症。曾多次尝试通过直接牵引经植入静脉取出导线,但均未成功,因为导线与右心室小梁紧密粘连。采用抗生素治疗的反复清创无效。作为最后手段,我们在首次植入后24个月和局部感染发作后22个月,最终在体外循环(ECC)下进行手术。由于我们发现即使在直视下通过牵引也难以取出导线,于是我们使用作为ECC回路一部分的氯乙烯管作为护套,在导线尖端周围施加反向牵引,以防止心肌壁被撕裂并与导线尖端一起被拔出。导线成功取出,并植入了一根新的心外膜导线。术后过程顺利,1年后未复发。在查阅日本文献时,详细描述了10例在ECC下手术取出感染的保留导线的病例。其中,8例曾进行过包括取出发生器和导线皮下部分在内的清创术。显然,为根除感染,必须移除整个起搏器系统。导线与心脏壁的粘连很牢固。除我们的病例外,只有1例成功取出导线而无需切开导线尖端周围的组织。(摘要截短至250字)
