OBJECTIVE: A minor part of patients with subclavian or innominate artery occlusive disease (subclavian artery stenosis [SAS]) experience symptoms of vertebrobasilar insufficiency, upper extremity exertional ischemia (UEEI), or cardiac ischemia owing to subclavian-coronary steal (SCS) in some instances. The study aimed to assess the impact of percutaneous transluminal angioplasty (PTA) of symptomatic SAS on symptom resolution and to determine factors related with SAS recurrence. METHODS: Symptom resolution and incidence of restenosis (RS) were evaluated for up to 15 years in patients who had undergone successful PTA of SAS...

Kommerell's diverticulum (KD) is defined as a bulbous dilatation of the origin of an aberrant subclavian artery due to a remnant of the left fourth aortic arch. We report the case of an asymptomatic woman in whom progressive thrombosis of the KD extending to the prevertebral tract of an aberrant right subclavian artery was detected at multidetector computed tomography imaging for lung cancer staging performed before and after the beginning of chemotherapy. Reversed blood flow in the ipsilateral vertebral artery due to subclavian steal phenomenon was also observed by color Doppler ultrasound examination...

The subclavian-vertebral artery steal syndrome (SSS) is the hemodynamic phenomenon of blood flow reversal in the vertebral artery due to significant stenosis or occlusion of the proximal subclavian artery or the innominate artery. Occasionally, SSS is diagnosed in patients not harboring arterial stenosis. With the exception of arterial congenital malformations, the limited case reports of SSS with intact subclavian artery are attributed to dialysis arteriovenous fistulas (AVFs). Interestingly, these cases are more frequently symptomatic than those with the classical atherosclerotic SSS forms...

PURPOSE: To report the use of a coronary bioresorbable vascular scaffold to treat subclavian artery disease. CASE REPORT: A 58-year-old man was admitted for left subclavian steal syndrome. Angiography showed significant left subclavian stenosis in proximity to the ostium of the left vertebral artery. To maximize radial support and minimize restenosis risk while avoiding the chance of vertebral compromise, a coronary bioresorbable vascular scaffold (3.5×28 mm) was implanted after predilation...

The study of steal mechanisms caused by vessel obstructions is of the utmost importance to gain understanding about their pathophysiology, as well as to improve diagnosis and management procedures. The goal of this work is to perform a computational study to gain insight into the hemodynamic forces that drive blood flow steal mechanisms caused by subclavian artery stenosis. Such condition triggers a flow disorder known as subclavian steal. When this occurs in patients with internal thoracic artery anastomosed to the coronary vessels, the phenomenon includes a coronary-subclavian steal...

BACKGROUND: Increased flow in the subclavian artery feeding a vascular access for hemodialysis can induce steal phenomena in the vertebral (VA) and internal mammary artery (IMA). The aim of this study was to describe the hemodynamic effects of access flow on the VA and IMA in patients with native fistulas and grafts. PATIENTS AND METHODS: Peak systolic (PSV) and end diastolic (EDV) velocity measurements of the VA, IMA and carotid arteries, as well as flow volume measurements of the subclavian artery, were performed...

BACKGROUND: Palliative procedures performed before the Fontan procedure may require ligation of the subclavian arteries, thereby affecting flow to the vertebral arteries. In adults with functionally univentricular heart disease, the implications of altered brainstem vascular anatomy for perioperative management of failing Fontan circulation are not known. METHODS: We identified abnormal posterior circulation anatomy in an adult patient with failing Fontan circulation who experienced a brainstem stroke after Fontan conversion...

BACKGROUND: Coronary subclavian steal syndrome (CSSS) is defined as retrograde flow in the internal mammary artery graft, after coronary artery bypass surgery, resulting in anterior wall myocardial ischemia. If undiagnosed, it may lead to significant infarction. Its incidence has been under-reported. CASE REPORT: A 74-year-old woman presented with sudden onset of typical angina, which was associated with dyspnea, nausea, and vomiting. Her medical history was significant for coronary artery disease, with prior coronary artery bypass surgery (CABG), chronic obstructive pulmonary disease (COPD), hypertension, diabetes type 2, dyslipidemia, hypothyroidism, and depression...

Subclavian artery stenosis can cause a flow reversal-so-called steal-not only in the ipsilateral vertebral artery, but also in the internal mammary artery in patients with a history of coronary-artery bypass grafting. Subclavian artery stenosis is also associated with peripheral artery disease elsewhere. We report a novel finding of axillo-femoral bypass steal due to subclavian artery stenosis identified by vascular ultrasonography.

Isolated subclavian artery arising from the pulmonary artery is exceedingly rare. Most cases are associated with other forms of congenital heart disease and typically present with subclavian or pulmonary steal syndromes. We report the case of a patient with pulmonary hypertension which masked the isolated subclavian artery, allowing it to masquerade as another common congenital heart lesion.

INTRODUCTION: In symptomatic subclavian steal syndrome, endovascular treatment is the first line of therapy prior to extra-anatomic surgical bypass procedures. Subintimal recanalization has been well described in the literature for the coronary arteries, and more recently, in the lower extremities. By modifying this approach, we present a unique retrograde technique using a heavy tip microwire to perform controlled subintimal dissection. METHODS: We present two cases of symptomatic subclavian steal related to chronic total occlusion of the left subclavian artery and right innominate artery, respectively...

PURPOSE: The study sought to evaluate the efficacy of magnetic resonance imaging (MRI) in patients with suspected subclavian steal syndrome (SSS) using both contrast-enhanced (CE) MR angiography and phase-contrast (PC) MRI. METHODS: Fifteen suspected SSSs from 13 patients were evaluated using CE-MR angiography and PC-MRI. Ten patients also received dynamic CE-MR angiography. RESULTS: All MRI examinations were technically successful. By combining CE-MR angiography with PC-MRI, 10 SSSs were diagnosed in 9 patients...

INTRODUCTION: In this case series, different modalities of treatment for patients with ischaemic symptoms of subclavian stenosis are described, including the different operative strategies that can be adopted in more challenging cases. This is the first case series describing these four management options. PRESENTATION: Case 1: A seventy-one year-old female presented with acute on chronic ischaemia of her left arm following a fall and developed dry gangrene of her left thumb...

UNLABELLED: Using recently developed diagnostic and treatment methods, we successfully diagnosed and treated a case of subclavian steal syndrome. Syncope and left upper arm weakness suggested ischemia of the cerebral and left upper arm circulation. Volume-plethysmographic blood pressure measurements clarified the differences between the upper arms simultaneously. A high-resolution Doppler instrument revealed a retrograde left vertebral artery waveform, indicating subclavian steal syndrome...

Right aortic arch with isolation of the left subclavian artery is a rare anomaly. The incidence of bilateral ductus arteriosus is sporadic, and a right aortic arch with isolation of the left subclavian artery in association with bilateral ductus arteriosus is therefore extremely rare. Since the symptoms and signs of isolation of the left subclavian artery can include the absence or underdevelopment of the left arm, subclavian steal syndrome, or pulmonary artery steal syndrome, the proper therapeutic approach is controversial...
