BACKGROUND
Subclavian venous occlusion sometimes precludes the ability to insert leads during placement of a cardiac implantable electronic device. This study was performed to identify the risk factors for spontaneous subclavian venous occlusion prior to placement of an implantable electronic device.
METHODS
We studied 446 patients who underwent axillary-subclavian venography to assess for occlusion and/or anomaly of the subclavian vein or associated veins before electronic device implantation.
RESULTS
Six (1.3%) patients had venous occlusion (left subclavian vein in 5, left innominate vein in 1). There was a significantly higher incidence of previous cancer in the occlusion group than in the nonocclusion group (11.5% vs. 50%, p = 0.03).
CONCLUSIONS
Subclavian venous occlusion may be present before cardiac implantable electronic device placement. A history of cancer represents a risk factor subclavian venous occlusion, and patients with this risk factor should undergo subclavian venography prior to electronic device placement.
背景
锁骨下静脉闭塞有时会妨碍在植入心脏植入式电子设备时插入导线。本研究旨在确定在植入可植入电子设备之前自发性锁骨下静脉闭塞的危险因素。
方法
我们研究了446例患者，这些患者在植入电子设备之前接受了腋-锁骨下静脉造影，以评估锁骨下静脉或相关静脉的闭塞和/或异常情况。
结果
6例（1.3%）患者出现静脉闭塞（5例为左锁骨下静脉，1例为左无名静脉）。闭塞组既往癌症的发生率显著高于非闭塞组（11.5%对50%，p = 0.03）。
结论
在植入心脏植入式电子设备之前可能存在锁骨下静脉闭塞。癌症病史是锁骨下静脉闭塞的一个危险因素，有此危险因素的患者在植入电子设备之前应接受锁骨下静脉造影。
