Right subclavian steal syndrome in a patient with aberrant right subclavian artery, common carotid trunk and hypoplastic left vertebral artery
نویسندگان
چکیده
Introduction: Subclavian steal syndrome refers to the reversal of vertebral blood flow in the setting of proximal subclavian or innominate artery severe stenosis or occlusion resulting in the symptoms of vertebrobasilar insufficiency related to exercise of the upper extremities. It is more common on the left side. Case report: We reported a case of subclavian steal syndrome on the right side in a patient with aberrant right subclavian artery (ARSCA), hypoplastic left vertebral artery and common carotid trunk (CCT) branching in to the left and right common carotid arteries. Conclusion: Till now, combination of ARSCA, CCT and left vertebral artery hypoplasia in the same person has not been reported and this combination causes ischemia in large area of brain if the patient develops hemodynamically significant stenosis or occlusion in both CCT and ARSCA proximal to the origin of right vertebral artery.

Two Cases of Aberrant Right Subclavian Artery and Right Vertebral Artery that Originated from the Right Common Carotid Artery
We present here two patients that had an aberrant right subclavian artery and an anomalous origin of the right vertebral artery from the right common carotid artery. We review the previous literature and discuss herein the embryologic mechanism and clinical implications of this variation.
متن کاملCritical carotid and vertebral arterial occlusive disease and cough syncope.
BACKGROUND AND PURPOSE Cough syncope typically occurs in patients with known chronic lung disease. The mechanism usually involves a combination of decreased venous return, increased cerebrospinal fluid pressure, and secondary hypocapnia, all resulting in cerebral arterial vasoconstriction. Cough syncope has not in the past been associated with occlusive cerebrovascular disease. CASE DESCRIPTI...

متن کاملRight subclavian steal associated with aberrant right subclavian artery.
The subclavian steal syndrome is a well-recognized clinical and radiographic entity that involves the left subclavian artery far more commonly than the right. Atherosclerotic stenoses are the most common underlying cause [1-3]. Right subclavian stenosis with associated steal is markedly less common. Although an aberrant right subclavian artery is one of the most common anomalies of the great ve...
متن کاملArch of aorta with bi-carotid trunk, left subclavian artery, and retroesophageal right subclavian artery.
We report a case of left sided aortic arch with three branches - a bi-carotid trunk, left subclavian, artery and right subclavian artery. The anomalous right subclavian artery presented a retroesophageal course. A right non-recurrent laryngeal nerve was noticed. The embryonic development of this branching pattern is discussed.
