Coronary subclavian steal syndrome (CSSS) is a rare cause of angina. It occurs in patients with prior coronary artery bypass grafting and, specifically, a left internal mammary artery (LIMA) to left anterior descending artery (LAD) graft and co-existent significant subclavian artery stenosis. In this context, there is retrograde blood flow through the LIMA to LAD graft to supply the subclavian artery beyond the significant stenosis. This potentially occurs at the cost of compromising coronary artery perfusion dependent on the LIMA graft...

The prevalence of subclavian artery (SA) stenosis is approximately 2%. The exact prevalence of extracranial vertebral artery (VA) stenosis is undetermined, with estimates ranging from 7% to 40%. Nearly 25% of ischaemic strokes involve the vertebrobasilar circulation, and arteriosclerotic disease and narrowing of the proximal VA may be the cause for up to one-fifth of these incidents. The bulk of SA stenoses occur proximally to the ostium of the VA. Vertebrobasilar ischaemia can be caused both by VA and SA stenosis...

Objectives and Background: To review technical details and long-term outcomes of endovascular treatment of chronic total occlusion (CTO) of the subclavian artery. Methods: From January 2010 to May 2017, 23 patients (17 male; median age, 65 years) underwent endovascular treatment for CTO of the subclavian artery. All lesions had been diagnosed by duplex scanning or computed tomography angiography before treatment. Sixteen (70.0%) patients had symptoms of vertebrobasilar insufficiency, 6 (26.1%) patients had symptoms of arm ischemia, and 2 (8...

An 81-year-old man presented with shortness of breath and was referred to our hospital with suspected acute pulmonary embolism. Enhanced computed tomography revealed a right aberrant subclavian artery with a thrombosed Kommerell diverticulum (KD), as well as deep vein thrombosis in the left leg and bilateral pulmonary artery thrombosis. Thrombosis in the KD disappeared after one month of anticoagulation treatment with rivaroxaban. Thrombosis of a KD is a rare condition that may cause distal emboli and subclavian steal syndrome, although this syndrome was not present in this case...

BACKGROUND Thyrocervical trunk pseudoaneurysms are rare complications that have been documented after internal jugular or subclavian venous cannulation. Even less common, these pseudoaneurysms can arise after blunt or penetrating trauma. Clinical hallmarks include an expanding supraclavicular mass with local compressive symptoms such as paresthesias, arterial steal syndrome, and Horner's syndrome. Patients may be asymptomatic, however, or present with overlying ecchymosis or the presence of a new bruit or thrill...

The first line approach for subclavian steal syndrome is PTA-stenting of subclavian artery. When the ipsilateral vertebral artery origin is involved or in closed proximity of the atherosclerotic lesion in the subclavian artery PTA-stenting is at risk of ipsilateral vertebral artery coverage. Herein we report our experience with DEB to address lesions involving the subclavian artery and the origin of the ipsilateral vertebral artery. From January 2017 to February 2019, patients presenting subclavian artery lesion involving the origin of the ipsilateral vertebral artery and treated using primary DEB, were included...

BACKGROUND: Patients with DeBakey type II aortic dissection or ascending aortic aneurysms involving the right innominate artery require hemiarch replacement and placement of a right innominate artery graft. Traditional aortic hemiarch replacement surgery must be performed under right axillary artery cannulation perfusion and moderate or deep hypothermia circulatory arrest. However, the axillary artery perfusion is always associated with left subclavian artery "steal blood", and it cannot guarantee blood supply to the left cerebral hemisphere in patients with an incomplete circle of Willis, and hypothermia and hypoperfusion cause damage to the brain and spinal cord; therefore, postoperative complications of the nervous system are common...

BACKGROUND: We investigated the mid-term results of carotid-axillary bypass (CAB) in the setting of zone II thoracic endovascular aortic repair as an alternative method for the left subclavian artery (LSA) revascularization. METHODS: Our retrospective single cohort study included all 69 patients from March 2015 to December 2018 with zone II thoracic endovascular aortic repair and CAB for the revascularization of the LSA. Demographics and clinical data were collected...

Extracranial vertebral artery (VA) atherosclerosis is responsible for 14% to 32% of posterior circulation infarctions.1 In the posterior circulation, narrowing of the VA > 30% is significantly associated with strokes. Subclavian artery (SCA) atherosclerosis can produce subclavian steal. Retrograde VA flow around an occluded SCA decreases blood flow to the posterior circulation and causes vertebrobasilar insufficiency (VBI). Flow augmentation to the posterior circulation can be achieved by VA endarterectomy, arterial stenting, VA-common carotid artery (CCA) transposition, or bypass using an interposition graft...

OBJECTIVE: Subclavian steal syndrome results from hemodynamic impairment due to stenosis or occlusion of subclavian artery. Therefore, it is important for subclavian steal syndrome patients to assess hemodynamic status during endovascular therapy. METHODS: Eleven subclavian steal syndrome patients undergoing endovascular therapy attended this study. Pressure wire was used to measure trans-stenosis pressure difference (ΔP). Digital subtraction angiography, Transcranial Doppler and Electronic sphygmomanometer were introduced to assess stenotic rate, steal grade and inter-arm systolic pressure difference, respectively...

We herein report a case of direct carotid-cavernous fistula(direct CCF)in a patient with masked hypertension caused by bilateral subclavian artery stenosis. A 74-year-old woman presented with headache, right-sided proptosis, double vision, and pulsatile tinnitus since past 10 days. The patient was diagnosed with direct CCF. Transarterial embolization in the region of the right internal carotid artery was performed, after which her symptoms resolved. However, additional interventions in the form of subclavian artery stenting were required, because of the complications of left subclavian artery occlusion and right subclavian artery stenosis...

Left subclavian artery revascularization during endovascular repair of aortic dissection is often accomplished by left carotid-subclavian artery bypass or transposition. In-situ fenestration of thoracic stent grafts provides an alternative method of revascularization without manipulation of the left carotid artery. We describe a case whereby in-situ laser fenestration, combined with catheter-directed thrombectomy was utilized to revascularize a thrombosed left subclavian artery following a frozen elephant trunk repair of type A aortic dissection...
