Though axillo-femoral bypass has been the preferred procedure since the introduction of the procedure by Blaisdell1) in 1963 for high risk patients who have aorto-iliac occlusive disease, widespread use of axillo-femoral bypass was limited in the past because long-term patency rates were inferior to aortofemoral bypass. Multiple mechanisms were mentioned for its inferior patency but delayed stenosis of the inflow artery(not at anastomosis site) were not reported frequently. The authors experienced one case of inflow malfunction of axillo-femoral bypass due to subclavian artery stenosis in a patient with coronary artery disease and carotid artery stenosis. Subclavian artery stenosis was treated by percutaneous transfemoral angioplasty with improvement of symptom and ABI.

We performed a hybrid procedure for a 58-year-old man with coronary artery disease and a left subclavian artery stenosis. He underwent left subclavian artery stenting and off-pump coronary artery bypass surgery, including grafting the in situ left internal mammary artery to the left anterior descending coronary artery. The post-operative coronary angiogram and computed tomography showed good patency of the graft and stent. He discharged at postoperative 8 days and he has been followed up for six month with an excellent clinical condition.

PURPOSE: We wanted to evaluate the clinical usefulness of percutaneous transluminal angioplasty (PTA) and stenting of left subclavian artery (LSA) stenosis in the patients with a left internal mammary artery (LIMA)-coronary artery bypass graft. MATERIALS AND METHODS: From September 1998 to November 2005, significant proximal LSA stenoses were treated with PTA and stenting in 22 patients (15 men and 7 women) who had a prior LIMA-coronary artery bypass graft or who were willing to undergo LIMA-coronary artery bypass grafting. The technical success rates, complications and restenosis during the follow-up period were retrospectively evaluated. RESULTS: Six patients had a prior LIMA bypass graft and 16 patients were treated before their coronary artery bypass surgery. The etiology of the LSA stenosis was atherosclerosis in all patients. Four patients were treated with PTA only, and stents were placed in 18 patients. Technical success was achieved in all patients. An embolism in the proximal LIMA occurred after stenting in one patient, and the LIMA was recanalized with transcatheter thrombolysis. During a mean follow-up of 30 months, only one patient was found to have recurrent LSA stenosis 29 months after stenting and this patient was successfully managed with angioplasty. CONCLUSION: Endovascular therapy is useful and efficacious for the treatment of LSA stenosis in patients with a LIMA-coronary artery bypass graft.

Myocardial revascularization using the left internal thoracic artery (LITA) has become a standard method for coronary artery bypass graft (CABG) surgery due to its long-term graft patency and lower repeated revascularization rate compared to a saphenous vein graft. The prevalence of significant subclavian artery stenosis was reported to be 0.2-6.8% in patients undergoing CABG surgery using LITA. We present a case of 49-year-old female patient who complained of resting chest pain and left arm pain after CABG surgery using the LITA. NSTEMI was caused by de novo subtotal left subclavian artery stenosis proximal to the LITA. The left subclavian artery was successfully stented, and the patient experienced complete relief of pain.

Subclavian steal syndrome is understood to be an occlusion or stenosis of the subclavian artery proximal to the origin of the vertebral artery with a retrograde flow of blood through the ipsilateral vertebral artery. It is characterized most prominently and most consistently by unequal blood pressures of both arms. In this case, we found incidentally unequal arm pressures during emergence. After the surgery, the 95% stenosis of left anterior descending coronary artery and total occlusion of subclavian artery was proved angiographically. This patient had the risk factors of atherosclerosis such as male, DM, hypertension, smoking and hyperlipidemia. In conclusion, pressures should be taken from both arms during initial visit, when the patient has the risk factors of atherosclerosis.

Coronary-subclavian steal through the left internal mammary graft is a rare cause of myocardial ischemia in patients who have had a coronary bypass surgery. We report a 70-year-old man who presented with sustained monomorphic ventricular tachycardia 5 years after the surgical creation of a left internal mammary to the left anterior descending artery. Cardiac catheterization illustrated that the left subclavian artery was occluded proximally and that the distal course was visualized by retrograde filling through the left internal mammary graft. Clinical ventricular tachycardia was reproducibly induced with a single ventricular extrastimulus, and antitachycardia pacing terminated the tachycardia. Restoration of blood flow by way of a Dacron graft placed between the descending aorta and the subclavian artery resulted in the total relief of symptoms. Ventricular tachycardia could not be induced during the control electrophysiologic study after surgical revascularization.

We report a case of coronary-subclavian steal syndrome, which had been masked by a malfunctioning hemodialysis access vessel and then reappeared after a successful angioplasty of multiple stenoses in the arteriovenous fistula of the left arm in a 61-year-old man. This case suggests that coronary-subclavian steal syndrome should be considered before a coronary artery bypass grafting surgery using internal mammary artery conduit is done, especially when hemodialysis using the left arm vessels is expected.

A 37-year-old woman who had undergone coronary artery bypass grafting (CABG) surgery for left main and right coronary ostial lesions 2 years prior presented with angina and transient visual dimness. Computed tomography angiography showed a patent left internal mammary artery (LIMA) bypass graft and concentric narrowing with perivascular thickening around the arch vessels. The patient was diagnosed with Takayasu arteritis with coronary subclavian steal syndrome (CSSS). Thoracic angiography revealed severe stenosis of the left proximal subclavian artery (SCA) and reverse flow from the coronary artery to the distal left SCA via the LIMA graft. Successful percutaneous stenting of the left SCA was performed together with stenting of the right common carotid artery (CCA). The patient's symptoms were completely resolved. This case is informative since it shows that Takayasu arteritis can manifest as angina due to coronary ostial lesions and then can involve arch vessels, which can lead to CSSS in patients with CABG.

A 60-year-old man visited the outpatient clinic due to one month of recurrent exertional chest pain. Eleven years earlier he had undergone off-pump coronary artery bypass grafting using bilateral internal thoracic artery (ITA) Y-composite grafts based on the left ITA. Preoperative coronary angiography showed patent distal graft anastomoses and visualized the left ITA retrogradely. The arch aortography revealed near-total occlusion of the left subclavian artery at the level of the ostium. The patient underwent left carotid-to-subclavian artery bypass grafting using a 6 mm vascular conduit. Postoperative computed tomographic angiography revealed a patent bypass conduit between the left common carotid artery and left subclavian artery. The patient was discharged on postoperative day 4 with no symptoms or signs of myocardial ischemia.

Coronary-subclavian steal (CSS) can occur after coronary artery bypass grafting (CABG) using the internal thoracic artery (ITA). Subclavian artery (SA) stenosis proximal to the ITA graft causes CSS. We describe a technique for cardiac and cerebral protection during endovascular stenting for CSS due to right SA origin stenosis after CABG. A 64-year-old man with a history of CABG using the right ITA presented with exertional right arm claudication. Angiogram showed a CSS and retrograde blood flow in the right vertebral artery (VA) due to severe stenosis of the right SA origin. Endovascular treatment of the right SA stenosis was planned. For cardiac and cerebral protection, distal balloon protection by inflating a 5.2-F occlusion balloon catheter in the SA proximal to the origin of the right VA and ITA through the right brachial artery approach and distal filter protection of the right internal carotid artery (ICA) through the left femoral artery (FA) approach were performed. Endovascular stenting for SA stenosis from the right FA approach was performed under cardiac and cerebral protection by filter-protection of the ICA and balloon-protection of the VA and ITA. Successful treatment of SA severe stenosis was achieved with no complications.
