Vascular access can present a clinical challenge in the implantation of permanent pacemaker leads. We describe the case of an 81-year-old man with complete heart block in whom it was difficult to find a suitable vein for advancing a pacemaker lead. The left cephalic vein was selected for lead implantation; however, because of a 90° angle between the cephalic and axillary veins, the lead failed to advance. Because the patient was elderly and at high risk, we decided to place a left ventricular pacing lead in the right ventricle by means of an over-the-wire technique. After 1 month, the patient's pacing threshold was good, and the lead remained in the right ventricular apex. When patients have distorted vessels and lead placement seems difficult or impossible, we think that the over-the-wire placement technique can be effective.
血管通路在永久性起搏器导线植入过程中可能带来临床挑战。我们描述了一名81岁完全性心脏传导阻滞男性患者的病例,在该患者中很难找到适合推进起搏器导线的静脉。选择左头静脉进行导线植入;然而,由于头静脉和腋静脉之间呈90°角,导线未能推进。由于患者年事已高且风险较高,我们决定通过导丝技术在右心室植入左心室起搏导线。1个月后,患者的起搏阈值良好,导线仍位于右心室心尖部。当患者血管扭曲且导线放置似乎困难或不可能时,我们认为导丝放置技术可能有效。
