We describe two cases of SVC tear during TLE. The first case was a 60-year-old man who presented with a right ventricular single-chamber defibrillator lead fracture and innominate vein stenosis. The RV lead was removed using a laser sheath causing a mediastinal hematoma with no active bleeding during surgical exploration few hours later. The second case was a 28-year-old man that presented with a right atrial (RA) lead fracture and RV lead insulation failure in a dual-chamber defibrillator (ICD).
Both the RA and RV leads were removed with mechanical sheaths, and a mediastinal hematoma was medically managed.
结果:我们描述了2例TLE期间SVC撕裂。第一例是一名60岁的男子,他表现为右心室单腔除颤器导线骨折和无名静脉狭窄。使用激光鞘去除RV导线,导致纵隔血肿,数小时后手术探查期间无活动性出血。第二例是一名28岁的男子,在双腔除颤器(ICD)中出现右心房(RA)导线断裂和RV导线绝缘故障。
结论:RA和RV导线均采用机械护套移除,纵隔血肿得到了医学治疗。
