Transvenous lead extraction is performed for device infection, lead failure, or to provide access for additional leads/device upgrade. A patient-centered risk assessment for transvenous lead extraction can be determined using a combination of clinical factors and several imaging modalities. Predicting a complex lead extraction, for example, one that will require powered tools or the use of a femoral approach, is aided by pre-procedural imaging and clinical assessment. Procedural imaging utilizing fluoroscopy, transesophageal echocardiography, and intracardiac echocardiography during an extraction can improve safety and identify complications rapidly.
经静脉导线拔除术适用于器械感染、导线故障，或为了提供额外的导线/器械升级通道。可以使用临床因素和多种影像学模式相结合的方法对经静脉导线拔除术进行以患者为中心的风险评估。例如，预测复杂的导线拔除术（需要使用动力工具或股静脉入路）有助于术前影像学和临床评估。在拔除术中利用透视、经食管超声心动图和心腔内超声心动图进行手术影像学检查，可以提高安全性并快速识别并发症。
