1/178. Bilateral subclavian steal syndrome through different paths and from different sites--a case report.Cases of cerebro-subclavian steal syndrome have been reported in the medical literature since 1960. This most often occurs on the left side because of the higher rate of involvement of the left subclavian artery in comparison to the other brachiocephalic branches of the aortic arch. With the use of the internal mammory artery as a conduit for coronary artery bypass, in the past three decades increasing numbers of coronary-subclavian steal in addition to the cerebro-subclavian steal have been observed. The authors report a case of bilateral subclavian steal syndrome through both vertebral arteries, the right common carotid artery, and the left internal mammory artery, without significant signs and symptoms of cerebral ischemia or anginal pain.- - - - - - - - - - ranking = 1keywords = artery, carotid, carotid artery (Clic here for more details about this article) |
2/178. Subclavian steal syndrome and flow-related aneurysm. Another reason to treat.A 48-year-old woman presented with a symptomatic right subclavian steal syndrome due to proximal subclavian artery stenosis. Anatomically the innominate artery was absent. collateral circulation followed the vertebro-vertebral pathway with reversal of blood flow in the ipsilateral vertebral artery. There was also multiple dilated intervertebral collaterals and an associated saccular aneurysm on one of them. Surgical carotid-subclavian transposition permitted relief of clinical symptoms, disappearance of collateral circulation and subtotal regression of the aneurysm. This spontaneous evolution confirmed the role of high-flow in the pathogenesis of some aneurysms and the habitually good prognosis of flow-related aneurysms with correction of the cause. Arteriography still appears essential in diagnosis, pretherapeutic assessment and sometimes post-treatment evaluation in subclavian steal syndrome.- - - - - - - - - - ranking = 0.60331359279732keywords = artery, carotid (Clic here for more details about this article) |
3/178. coronary-subclavian steal syndrome: treatment with percutaneous transluminal angioplasty and stent placement.The aim of this study was to assess the efficacy of percutaneous transluminal angioplasty (PTA) and stenting in the management of the coronary-subclavian steal syndrome (CSSS). A 56-year-old man presented with CSSS due to occlusion of the left subclavian artery. He was treated with PTA and placement of two stents in the left subclavian artery. Systolic blood pressure became equal in both arms and dizziness disappeared. There were no complications. Percutaneous transluminal angioplasty and stenting can effectively and safely manage CSSS.- - - - - - - - - - ranking = 0.31570652743257keywords = artery (Clic here for more details about this article) |
4/178. Right aortic arch with isolation of the left subclavian artery, moderate patent ductus arteriosus, and subclavian steal syndrome: A rare aortic arch anomaly treated with the Gianturco-Grifka vascular occlusion device.We present the first described use of the Gianturco-Grifka Vascular Occlusion Device to close a moderate patent ductus arteriosus associated with the rare congenital condition of right aortic arch with isolation of the left subclavian artery. Left vertebral artery "steal" through the moderate patent ductus arteriosus was eliminated by this transcatheter technique. Cathet. Cardiovasc.

5/178. Endoluminal stenting for subclavian artery stenosis in Takayasu's arteritis.We describe a patient with Takayasu's arteritis (type I): occlusion of all large vessels of the aortic arch except the left subclavian artery which was, however, almost completely occluded, resulting in a characteristic subclavian steal syndrome. Elective left main subclavian artery balloon angioplasty followed by endoluminal stenting was performed with excellent results. After prolonged immunosuppressive treatment, at the 12-month follow-up there was no evidence of restenosis. In selected patients with Takayasu's arteritis and subclavian stenosis, elective endoluminal stenting can be used as a definitive procedure or as a bridge to surgical revascularization.- - - - - - - - - - ranking = 0.94711958229772keywords = artery (Clic here for more details about this article) |
6/178. Coronary-subclavian steal associated with severe aortic stenosis treated with combined percutaneous stenting and minimally invasive aortic valve replacement.We describe coronary-subclavian steal restricting flow to the left internal mammary artery (LIMA) associated with critical aortic stenosis treated with combined percutaneous transluminal stenting and minimally invasive aortic valve replacement (AVR). An 86-year-old patient had coronary artery bypass graft placement (CABG) seven years prior with the LIMA anastomosed to the left anterior descending coronary artery (LAD). At the time of CABG, the patient had mild aortic stenosis and normal left ventricular function. By the time of re-presentation with refractory angina and heart failure, the patient had developed critical aortic stenosis. Because repeat CABG with median sternotomy risked damaging the LIMA, pre-operative revascularization was planned to minimize the likelihood of peri-operative ischemia. Stenting of the subclavian artery was performed prior to minimally invasive AVR.- - - - - - - - - - ranking = 0.63141305486515keywords = artery (Clic here for more details about this article) |
7/178. Relocation of the internal mammary artery graft in a case of coronary-subclavian steal.Reverse flow in the internal mammary artery coronary graft in the presence of subclavian stenosis is rare. We describe a 67-year-old man who 7 years after coronary artery surgery was admitted with left subclavian artery stenosis and retrograde flow in the pedicled left internal mammary artery graft. Subsequent redo triple coronary artery bypass grafts included regrafting the left internal mammary artery graft to a new vein conduit.- - - - - - - - - - ranking = 1.5785326371629keywords = artery (Clic here for more details about this article) |
8/178. Evaluation of coronary subclavian steal syndrome using sestamibi imaging and duplex scanning with observed vertebral subclavian steal.Coronary subclavian steal is defined as retrograde blood flow from the myocardium through the internal mammary artery graft, secondary to a proximal subclavian artery stenosis. The incidence of this syndrome in patients undergoing internal mammary artery grafts for coronary artery bypass is estimated to be 0.44%. angiography remains the definitive diagnostic test for confirming this condition. We describe a noninvasive method for evaluating coronary subclavian steal syndrome in a 57-year-old man, with a 50-55% subclavian stenosis confirmed by angiography. Noninvasive evaluation using duplex scanning demonstrated normal vertebral artery blood flow. technetium 99m-sestamibi (99mTc) imaging confirmed a fixed anterolateral defect. When left-arm isometric exercise was employed, retrograde vertebral artery blood flow was observed by Doppler imaging. A repeat 99mTc-sestamibi study documented an increase in tracer distribution in the anterolateral defect confirming reperfusion of the myocardium through the left internal mammary artery graft. The use of duplex scanning and 99mTc-sestamibi may serve as an adjunct in evaluating coronary subclavian steal syndrome as well as documenting transient vertebral subclavian steal in this patient population.- - - - - - - - - - ranking = 1.104972846014keywords = artery (Clic here for more details about this article) |
9/178. Isolated origin of the left subclavian artery from the left pulmonary artery.We describe two children with isolated origin of the left subclavian artery from the left pulmonary artery detected by echocardiography during the assessment of their congenital cardiac malformations. Both patients demonstrated pre-operative evidence of subclavian steal. This entity results from persistence of the dorsal segment of the sixth left arch, with regression of the left fourth arch and interruption of the left dorsal arch distal to the origin of the seventh left intersegmental artery. The significance of this finding relates to the potential for pulmonary overcirculation, which could have significant post-operative ramifications if not detected prior to surgical repair of an associated cardiac malformation. This entity differs from cases with a right aortic arch and aberrant left subclavian artery which has the potential to form a vascular ring, unlike cases with isolated origin of the left subclavian artery from the pulmonary artery that do not cause compression of the airway.- - - - - - - - - - ranking = 2.209945692028keywords = artery (Clic here for more details about this article) |
10/178. Symptomatic subtotal occlusion of the innominate artery treated with balloon angioplasty and stenting.PURPOSE: To report the endovascular treatment of a subtotal occlusion of the innominate artery giving rise to subclavian steal syndrome. methods AND RESULTS: A 60-year-old man in general good health was admitted to the hospital for sudden onset of amaurosis in the right eye. thrombosis of the central retinal artery was diagnosed. physical examination, color flow duplex imaging, and aortic arch angiography showed a subtotal occlusion of the innominate artery with right subclavian steal syndrome. One month later, balloon dilation and stenting of the innominate artery was performed through a right axillary access without cerebral protection. The innominate artery was recanalized with correction of the steal syndrome and restoration of the right radial pulse; no complications occurred. Twelve months later, color flow duplex sonography confirmed innominate stent patency and antegrade flow in the right vertebral artery. CONCLUSIONS: Our experience supports the view that percutaneous endovascular techniques are appropriate and are the preferred treatment for lesions of the supra-aortic vessels. Continued surveillance will determine their long-term durability.- - - - - - - - - - ranking = 1.5785326371629keywords = artery (Clic here for more details about this article) |
