Persistent left superior vena cava occurs in approximately 0.5% of the population. This may complicate pacemaker implantation by making lead insertion difficult and causing lead instability through the left cephalic vein and the subclavian vein approach. We used a wide loop technique in the right atrium and successfully advanced the lead in the right ventricle apex. A persistent left superior vena cava does not preclude successful lead placement.
永存左上腔静脉在大约0.5%的人群中出现。这可能会使起搏器植入复杂化，因为通过左头静脉和锁骨下静脉途径插入导线困难，并导致导线不稳定。我们在右心房采用了宽环技术，并成功地将导线推进到右心室心尖。永存左上腔静脉并不妨碍导线的成功放置。
