“…Szawlowsky (1888) mentioned a slightly enlarged origin of this artery; in addition, a drawing in an article by Paterson (1884) shows a widening at the beginning of the RRVA, but no respective comments were made in the text. An initial dilatation of the right retroesophageal subclavian artery (RRSA) occurs in about 60% of these cases; it is named aortic diverticulum or diverticulum of Kommerell by clinicians and is usually interpreted as residue of the right dorsal aortic root (Schmidt, 1953;Walker and Geller, 1987).…”

“…Esophageal indentation, for example, recognized as a specific radiologic sign for an RRSA (Kommerell, 19361, may, in fact, be caused by a dilatation of an RRVA; such "aortic diverticula" can produce various clinical symptoms and angiographic misinterpretations (Walker and Geller, 1987). Proximal stenosis of a subclavian artery may lead to collateral blood flow from the vertebrobasilar arteries to the arm and to brain ischemia, a phenomen called "subclavian steal syndrome."…”

We describe a case of an aortic arch with five primary branches arising in a sequence that has previously never been reported. From right to left, the brachiocephalic trunk and left common carotid, left vertebral, and subclavian arteries originated from the convexity of the aortic arch. The last branch was the right vertebral artery that arose from the dorsal aspect of the aortic arch opposite the ligamentum arteriosum. Presenting a dilatation at its commencement, the right vertebral ran to the right behind the esophagus and entered the foramen transversarium of the seventh cervical vertebra, whereas the left vertebral passed to the foramen transversarium of the fifth cervical vertebra. The left vertebral artery gave off the left thyroid artery; a thyrocervical trunk was absent on the left side. A thyroidea ima arose from the brachiocephalic trunk. The embryology of this complex anomaly as well as its potential clinical significance are discussed.

“…The incidence is reportedly 0.05% for ALSA with right aortic arch and 0.5% to 2.0% for ARSA with left aortic arch 1 . The left aortic arch with ARSA is the most common aortic arch anomaly involving the subclavian artery 2,3 .…”

Two cases of aberrant subclavian arteries were detected incidentally during computed tomography scan of the thorax for other medical conditions. The patients did not have weight loss or dysphagia lusoria. The origin and course of the aberrant subclavian arteries are related to the anomaly of the aortic arch. The variations of aberrant right subclavian artery with left aortic arch and aberrant left subclavian artery with right aortic arch on computed tomography are discussed.

“…Abnormal elastic fibers and muscular planes of the vessel wall have been implicated in congenital true aneurysm and/or dissection of congenitally abnormal vessel such as the extraordinary widening of an aberrant right subclavian artery, unusually large ductus diverticula or aneurysm of a cervical arch or an unusually large diverticulum of Kommerell [9][10][11][12].…”

Aortic dissection with extension to a patent ductus arteriosus

An 81-year-old woman presented with shortness of breath and fever of 3 days duration. An enhanced CT of the chest revealed a patent ductus arteriosus (PDA) communicating with the true lumen of an aortic arch dissection. Neither the aortic dissection nor the PDA was suspected. The patient had no history of a connective tissue abnormality or other condition which would predispose to dissection other than systemic hypertension. It is likely that propagation of the aortic dissection partially re-opened the ductus arteriosus.
