A retroesophageal right subclavian artery with the right vertebral artery originating from the right common carotid artery

The right subclavian artery was found to be retroesophageal, and the right vertebral artery originated from the right common carotid artery in a 46-year-old female cadaver. The right subclavian artery stemmed from the upper portion of the thoracic aorta, posterior and inferior to the origin of the normal left subclavian artery. The right and left common carotid arteries originated from the aortic arch in close proximity. Compression of the trachea anteriorly could not be demonstrated. The right inferior laryngeal nerve was nonrecurrent. A brief review of the literature shows the importance of knowledge concerning the aberrant right subclavian artery for the roentgenologist and the surgeon in the treatment of patients with this vascular anomaly.     

右肾动脉、睾丸动脉及肾上腺下动脉变异1例

Posterior right diagonal artery

Background: There is general confusion about a branch of the posterior segment of the right coronary artery that has been referred to as 1) the lower trunk of a divided right coronary artery; 2) a posterior reflection of the right marginal artery; 3) the ramus lateralis; and 4) a posterolateral branch or a posterior descending artery. Materials: Three hundred human hearts were studied by direct observation, X-ray films, and corrosion casting. Results: This branch of the right coronary artery arises either after the right marginal artery (in 84% of hearts) or it constitutes the continuation of this artery in the remaining 16%. We named it the posterior right diagonal artery (PRDA). It was found in 14% of 266 hearts of right dominant type. It was present in 39% when the length of the posterior descending artery (PDA) was shorter than half of the length of the posterior interventricular sulcus (PIS) and in 6% when it was longer. When the PRDA originated directly from the RCA, the RMA appeared underdeveloped; the PRDA always occupied the inferior part of the PIS and appears either as continuation of a short PDA or as a replacement for a long PDA from the point where this artery leaves the PIS to enter the posterior wall of the left ventricle. The PDRA when present serves as a bridge between the RCA and the left anterior descending artery. Conclusions: These findings are of practical importance for the correct interpretation of coronary arteriographies and in the field of coronary artery surgery. © 1994 Wiley-Liss, Inc.     

Truncus bicaroticus with aberrant right subclavian artery and origin of right vertebral from right common carotid artery

We describe a rare constellation of variant anatomy of the aortic arch branches, seen on a magnetic resonance angiographic examination during the course of investigation for recent onset memory loss in a 52-year-old patient. There was a common origin of both the common carotid arteries (CCA), the common trunk being the first major branch of the aortic arch, the right vertebral artery arising from the right CCA and the right subclavian artery arising as the last branch of the arch. In isolation, the three components of this constellation have been reported with different frequencies, but as per the authors’ knowledge, this entire constellation has been rarely reported. We review the literature and propose an embryological mechanism for this variant anatomy.

Superdominant right coronary artery with absent left circumflex artery

Noninvasive imaging of coronary artery disease is rapidly replacing angiography as the first line of investigation. Multislice CT is the non-invasive modality of choice for imaging coronary artery disease and provides high speed with good spatial resolution. CT coronary angiography in addition to detecting and characterising atherosclerotic coronary artery disease is also a good imaging tool for evaluating anomalies of coronary arteries. Superdominant right coronary artery with absent left circumflex artery is one such rare coronary artery anomaly which is well evaluated with multislice CT angiography. The authors report one such case of superdominant right coronary artery with absent left circumflex artery imaged with 64-slice MDCT.
