A retroesophageal right subclavian artery, arising from the arch of the aorta as the terminal branch and passing dorsal to the esophagus, was found in five (1.2%) of 428 bodies donated for student dissection at Kumamoto University between 1993 and 2008. The presence of a retroesophageal right subclavian artery has been generally explained to be caused by the persistence of the normally eliminated part of the right dorsal aorta caudal to the seventh intersegmental artery and the disappearance of the normally patent right fourth aortic arch and the part of the right dorsal aorta cranial to the seventh intersegmental artery during the developmental process. However, the parts which remain or disappear are different in each case. With the aim of determining the portions eliminated or persisting and thereby gaining an understanding of the developmental process of the retroesophageal right subclavian artery in each instance, we made schematic diagrams showing the various components of the embryonic aortic arch complex as the prototype just before the anomaly occurred. Based on these diagrams, we conclude that immediately preceding the disappearance of the distal part of the right dorsal aorta and the dorsal part of the right sixth aortic arch, the third intersegmental artery was situated opposite to the fourth aortic arch and the seventh intersegmental artery was situated cranial to the point of junction of the right and left dorsal aortae.

Aortic arch reconstruction in the Norwood procedure is occasionally associated with postoperative airway and branch pulmonary artery stenosis, as well as recoarctation. This study investigated geometr...
Anomalies of the aortic arch are frequent congenital malformations, which rarely form partial or complete vascular rings. A rare form of vascular ring is the encircling, or circumflex, aortic arch.
Double aortic arch (DAA) is the most common congenital anomaly of the aortic arch system, in which the trachea and esophagus are completely encircled by connected segments of the aortic arch and its b...
The purpose of this study is to access the outcomes of aortic bypass graft placement in children. This is a retrospective review of all children having aortic bypass graft placement for aortic arch ob...
This study aimed to simplify an until-now complex procedure for the treatment of proximal aortic arch pathology (zones 0 and 1), where a deep hypothermic circulatory arrest even with selective cerebra...
The ARCH is a controlled trial with a sequential design and with a prospective, randomized, open-label, blinded-endpoint (PROBE) methodology. The objective is to compare the efficacy and t...
Abnormalities of the aorta have been identified in patients who have undergone repair of coarctation of the aorta by various surgical techniques. These abnormalities are thought to contri...

The purpose of this study is to look at the safety (what are the side effects) and efficacy (how well does it work) of Magnevist (the study drug) used for MRI of the aortic arch and cerebr...
Perioperative blood loss continues to be a serious problem in complex aortic arch surgery using deep hypothermic circulatory arrest (DHCA). Major blood loss causes increased morbidity and ...
Small clusters of chemoreceptive and supporting cells located near the ARCH OF THE AORTA; the PULMONARY ARTERIES; and the coronary arteries. The aortic bodies sense PH; CARBON DIOXIDE; and oxygen concentrations in the BLOOD and participate in the control of RESPIRATION. The aortic bodies should not be confused with the PARA-AORTIC BODIES in the abdomen (which are sometimes also called aortic bodies).
A birth defect characterized by the narrowing of the AORTA that can be of varying degree and at any point from the transverse arch to the iliac bifurcation. Aortic coarctation causes arterial HYPERTENSION before the point of narrowing and arterial HYPOTENSION beyond the narrowed portion.
The first and largest artery branching from the aortic arch. It distributes blood to the right side of the head and neck and to the right arm.
A cardiovascular procedure performed to create a blood supply to the PULMONARY CIRCULATION. It involves making a connection between the subclavian, or carotid branch of the AORTA, or the AORTIC ARCH to the PULMONARY ARTERY.
Small masses of chromaffin cells found near the SYMPATHETIC GANGLIA along the ABDOMINAL AORTA, beginning cranial to the superior mesenteric artery (MESENTERIC ARTERY, SUPERIOR) or renal arteries and extending to the level of the aortic bifurcation or just beyond. They are also called the organs of Zuckerkandl and sometimes called aortic bodies (not to be confused with AORTIC BODIES in the THORAX). The para-aortic bodies are the dominant source of CATECHOLAMINES in the FETUS and normally regress after BIRTH.
Barrett’s esophagus is a condition in which the tissue lining the esophagus—the muscular tube that carries food and liquids from the mouth to the stomach—is replaced by tissue that is similar to the intestinal lining. This process is ca...
