Inter-arm variability in blood pressure readings typically signifies arterial disease between the aortic arch and the subclavian artery. The differential diagnosis includes thoracic aortic dissection, atherosclerosis, thoracic outlet syndrome, and subclavian artery stenosis and thrombosis. In patients with prior coronary artery bypass grafting, including the internal mammary artery, several of those conditions can compromise coronary blood flow and lead to myocardial ischemia. Here we discuss a case of left subclavian artery thrombosis, which compromised left internal mammary artery blood flow and led to ischemic ventricular tachycardia.
两臂血压读数的差异通常表明主动脉弓和锁骨下动脉之间存在动脉疾病。鉴别诊断包括胸主动脉夹层、动脉粥样硬化、胸廓出口综合征以及锁骨下动脉狭窄和血栓形成。在既往接受过包括乳内动脉在内的冠状动脉旁路移植术的患者中,上述几种情况可能会影响冠状动脉血流并导致心肌缺血。在此,我们讨论一例左锁骨下动脉血栓形成的病例,该病例影响了左乳内动脉血流并导致缺血性室性心动过速。
