چکیده

three major arteries normally originate from the aortic arch. variations of the aortic arch branches are observed in some cases. rare variation of the aortic arch branches is originated from the retroesophageal right subclavian (rrs) artery as the last branch of the aortic arch. variation of artery is possibly associated with the variation of the recurrent laryngeal nerve. this research provides an in vivo report of retroesophageal right subclavian artery during examination of the cervical vessels using magnetic resonance angiography (mra). it is very important to consider the variation of the right subclavian artery during head and neck surgery. non-invasive techniques such as mra of cervical arteries can be used in order to examine them.

A Rare Variation of Right Subclavian Artery Origin from Posterior Surface of Aortic Arch

Purpose: Several variations of aortic arch have been reported yet. In present study another variation of aortic arch was reported. Right subclavian artery arises from posterior surface of the distal end of the aortic arch. Case Report: we present a variation of an aorticarch in which right subclavian artery arisesfrom posterior surface of the distal end of the aortic arch and passing behind eso...

Right Aortic Arch with a Retroesophageal Left Subclavian Artery and an Anomalous Origin of the Pulmonary Artery from the Aorta

We report the case of a newborn with a rare anatomic variation: a right aortic arch with a retroesophageal left subclavian artery and an anomalous origin of the pulmonary artery from the aorta. This variation was diagnosed using echocardiography and computed tomography, and we treated the condition surgically.

Arch 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.

Three cases of retroesophageal right subclavian artery.

We have experienced three cases of retroesophageal right subclavian artery. Two cases were cadavers, and one case was a live human. In the two cadavers of a 68-year-old and a 76-year-old, respectively Japanese and European males, the right subclavian artery originated from the aorta after the aorta branched the right carotid artery, the left carotid artery and the left subclavian artery. The ri...
