The number of patients with arrhythmia and ischaemic heart diseases is increasing. Patients with pacemaker implantation sometimes have brachiocephalic vein occlusion, and several aetiologies have been reported. However, coronary artery bypass grafting using the internal thoracic arteries is not fully discussed in the literature. We present a case of failed percutaneous pacemaker implantation due to bilateral brachiocephalic vein occlusion 8 years after coronary artery bypass grafting using the bilateral internal thoracic arteries. There were rich collateral veins consisting of hemiazygos and azygos veins. We then performed surgical implantation instead. Contrast CT or venography for such patients might be considered.
心律失常和缺血性心脏病患者的数量正在增加。植入起搏器的患者有时会出现头臂静脉闭塞,并且已经报道了多种病因。然而,文献中对使用胸廓内动脉进行冠状动脉旁路移植术的讨论并不充分。我们报告一例在使用双侧胸廓内动脉进行冠状动脉旁路移植术8年后,因双侧头臂静脉闭塞导致经皮起搏器植入失败的病例。存在由半奇静脉和奇静脉组成的丰富侧支静脉。然后我们改为进行手术植入。对于此类患者,可能需要考虑进行对比CT或静脉造影。
