Patients with multivessel coronary artery disease are more likely to have extensive atherosclerosis that involves other major arteries. Critical subclavian artery (SCA) stenosis can result in coronary subclavian steal syndrome that may present as recurrent ischemia and even myocardial infarction in patients with coronary artery bypass graft (CABG). In patients with concomitant severe native cor...

Fig. 1. CTaxial image (a) evidences the anomalous origin of both carotid arteries from a unique trunk and demonstrates the presence of an aberrant right subclavian artery which passes ahead the thoracic spine inducing extrinsic compression of the esophagus. The origin of the bi-carotid trunk, which arises directly from the aortic arch, is more clearly viewable in the MPR image (b). Fig. 2. Pre-...

The Subclavian Steal Syndrome is a condition that results from the stenosis or occlusion of the subclavian artery proximal to the origin of the vertebral artery. The blockage causes the reversal of the normal direction of blood flow in the vertebral artery which is termed the "steal", because it steals blood from the cerebral circulation. Blood is drawn from the contralateral vertebral, basilar...

Subclavian artery dissection is rarely reported in the medical literature. We describe the case of a 54-year-old male who presented with multifocal ischemic stroke and was found to have a subclavian artery dissection. We provide an overview of the current literature discussing previously reported cases, clinical features, and treatment.

INTRODUCTION Collateral muscular artery aneurysm is exceedingly rare. We report the first case of subscapular artery aneurysm in a patient with type 1 neurofibromatosis and ipsilateral chronic subclavian artery occlusion. CASE PRESENTATION A 74-year-old Caucasian woman with a medical history of type 1 neurofibromatosis, presented a sudden left pectoral mass, later diagnosed as a ruptured aneu...

The present report describes an anomalous case of the left vertebral artery arising from the aortic arch between the left common carotid artery and the left subclavian artery in a male cadaver during dissection in an anatomical laboratory. Aortic origin of the vertebral artery is a rare anatomic variant. Detailed knowledge of anomalous origin is important for patients who undergo four-vessel an...

Fig. 1. Upper left oblique view using a volume rendering technique from heart and great vessels. Ascending aorta (AA) is medial and gives rise first to left carotid artery (LCA), then to right carotid artery (RCA) and right subclavian artery (RSCA), left subclavian artery (LSCA) arising from the upper part of the descending aorta. The aortic arch is right sided (RAA) and its distal portion is v...

BACKGROUND Variations of vessels arising from the aortic arch are numerous. One of the common anatomical variations is the right subclavian artery originating as the last branch of the aortic arch. This is a report of a case of an adult male cadaver with a retroesophageal right subclavian artery. OBJECTIVE To highlight the significance of a retroesophageal right subclavian artery, especially ...

S artery injury in blunt trauma is uncommon. The surgical repair of such an injury can be a major challenge. Because penetrating injuries are more common, many trauma surgeons have relatively little experience in dealing with blunt subclavian artery injury. This case is the first report of acute or immediate endovascular repair with pseudoaneurysm stenting of the subclavian artery, as a result ...

OBJECTIVE The objective of this work is to present an objective, practical, and reproducible method for evaluating the functional limitation caused by occlusive arterial disease in upper limbs: a stress test using an isokinetic dynamometer. METHODS Twenty-three patients with unilateral subclavian artery occlusive disease were included in the study, forming group 1. Seven patients of similar a...
