Coronary Subclavian Steal Syndrome

Subclavian artery stenting for coronary‐subclavian steal syndrome

“…The time elapsed between bypass surgery and the diagnosis of CSSS differed from previous studies . In our study, the mean time was 6.3 years.…”

“…Coronary‐subclavian steal syndrome (CSSS), usually refers to a reversed blood flow from the myocardium to the upper limb due to ipsilateral subclavian artery stenosis (SAS) in patients with internal mammary artery‐coronary bypass grafts (IMA‐CABG) . CSSS is an unusual cause of myocardial ischemia and IMA failure . Recent studies have revealed that the prevalence of significant SAS in patients scheduled for CABG ranged from 0.2% to 6.8%; SAS could develop into CSSS if ignored before cardiac surgery.…”

Endovascular treatment of coronary subclavian steal syndrome complicated with STEMI and VF: A case report and review of the literature

“…Coronary subclavian steal syndrome has two methods of treatment, endovascular manipulation and surgery. Although till now, no randomized trials have been performed to compare the efficacy of one strategy versus another, the percutaneous revascularization seems to be at least equivalent to surgery in terms of effectiveness with less procedure‐related serious complications . It was stated in the 2011 ACC/AHA guidelines that surgical and endovascular revascularization can both be considered as first‐line treatment of SA stenosis.…”

Stenting for left subclavian artery stenosis in patients scheduled for left internal mammary artery‐coronary artery bypass grafting

“…In the past two decades, more than 90% of patients who underwent CABG received a left internal mammary artery (LIMA) bypass to the left anterior descending (LAD) artery , particularly with the development of hybrid myocardial revascularization, which was believed to be more promising in patients with coronary multivessel disease . However, the presence of a proximal left subclavian artery stenosis (LSAS) prior to bypass surgery would compromise inflow to a LIMA‐LAD bypass, which might result in coronary‐subclavian steal syndrome (CSSS), and might manifest as angina pectoris or even myocardial infarction .…”
