Kommerell diverticulum (KD) is a developmental anomaly of the aortic arch characterized by a diverticulum at the proximal descending aorta of left or right arch configuration that gives rise to an aberrant subclavian artery..
Similarly one may ask, what is aortic diverticulum?
Abstract. The aortic diverticulum, a large bulge on the lesser curvature of the aortic isthums, is an occasional variation found during thoracic aortography in patients with a left aortic arch and normal origin of the brachiocephalic arteries.
Also Know, what causes aberrant right subclavian artery? The aberrant origin of the right subclavian artery is caused by the involution of the right fourth vascular arch and proximal right dorsal aorta and the persistence of the seventh intersegmental artery originating from the proximal descending thoracic aorta, forming the abnormal course of the artery lusoria [5, 6].
Similarly one may ask, what does Lusoria mean?
Dysphagia lusoria (or Bayford-Autenrieth dysphagia) is an abnormal condition characterized by difficulty in swallowing caused by an aberrant right subclavian artery. It was discovered by David Bayford in 1761 and first reported in a paper by the same in 1787.
What causes right aortic arch?
This condition is most often associated with congenital cardiac defects including tetralogy of Fallot, pulmonary atresia, atrial septal defects, truncus arteriosus, patent ductus arteriosus, and right-sided aortic arch, and is also often associated with pulmonary hypertension.

What is a ductus bump?
ABSTRACT : The ductus arteriosus may appear as a left mediastinal mass, the "ductus bump," on chest roentgenograms of the newborn infant. These lead to the conclusion that the ductus bump is a "normal" mass, transient and physiologic, presenting on chest roentgenogram of infants in the first day of life.Is right sided aortic arch dangerous?
A right-sided aortic arch does not cause symptoms on itself, and the overwhelming majority of people with the right-sided arch have no other symptoms. However when it is accompanied by other vascular abnormalities, it may form a vascular ring, causing symptoms due to compression of the trachea and/or esophagus.What is a right aortic arch?
A right aortic arch occurs when the aortic arch traverses over the right bronchus instead of the left bronchus (which defines a left aortic arch). Embryologically, this develops when the right dorsal aorta persists, and the left dorsal aorta regresses.What is an aberrant left subclavian artery?
Aberrant subclavian artery, or aberrant subclavian artery syndrome, is a rare anatomical variant of the origin of the right or left subclavian artery. This abnormality is the most common congenital vascular anomaly of the aortic arch, occurring in approximately 1% of individuals.What is a double aortic arch?
DAA. Double aortic arch is a relatively rare congenital cardiovascular malformation. DAA is an anomaly of the aortic arch in which two aortic arches form a complete vascular ring that can compress the trachea and/or esophagus.What is Arteria Lusoria?
Arteria Lusoria or aberrant right subclavian artery (ARSA) is the most common congenital arch anomaly in which the right subclavian artery originates from the descending aorta, distal to the left subclavian at the ductus arteriosus [1].What is an aberrant subclavian artery?
Aberrant right subclavian artery (ARSA) is a rare anomaly, in which the right subclavian artery arises directly from the aortic arch instead of originating from the brachiocephalic artery. This anomaly should be taken into consideration during surgical procedures around esophagus, such as esophagectomy.What happens if the subclavian artery is blocked?
Subclavian artery disease involves a narrowing of the arteries that supply blood to your upper body. Often, subclavian artery disease does not cause any symptoms because the disease progresses slowly or the body creates blood vessels around the blockage to maintain flow—or both.How common is aberrant right subclavian artery?
Aberrant right subclavian artery (ARSA) is the most common anomaly of the aortic arch. Its incidence varies from 0.5 to 2.5 % [1]. The artery originates on the left side as a last branch of the aortic arch beyond the left subclavian artery.What causes ARSA heart?
An aberrant right subclavian artery (ARSA) is a rare vascular anomaly that is believed to induce feeding and swallowing difficulties in 20% of the patients, caused by dorsal compression of the esophagus by the anomalous artery.What does the right subclavian artery do?
They receive blood from the aortic arch. The left subclavian artery supplies blood to the left arm and the right subclavian artery supplies blood to the right arm, with some branches supplying the head and thorax.Is aberrant right subclavian artery hereditary?
A case of a maternal and fetal aberrant right subclavian artery like the one we report here could be an incidental finding, close to 1 per 10,000. However, it can be useful to consider that an aberrant right subclavian artery could be a possible inherited malformation.What is ARSA heart?
What is an Aberrant Right Subclavian Artery (ARSA)? ARSA is a relatively common variation of the vessels of the Aortic Arch. The Aorta is one of the great blood vessels that deliver blood from the heart: it supplies oxygen-rich blood to the head and body.Where does subclavian vein drain?
It is one of the deep veins of the neck. The subclavian vein originates at the outer border of the first rib, it runs in the subclavian groove, then laterally to the medial border of the anterior scalene. At this point, the subclavian vein joins with the internal jugular vein to form the brachiocephalic vein.What is a vascular ring?
A vascular ring is a congenital defect in which there is an abnormal formation of the aorta and/or its surrounding blood vessels. The trachea and esophagus are completely encircled and sometimes compressed by a "ring" formed by these vessels, which can lead to breathing and digestive difficulties.What causes subclavian stenosis?
The most common cause of subclavian artery stenosis is atherosclerosis but other causes include congenital abnormalities such as arteria lusoria (aberrant subclavian artery) or right sided aortic arch that can cause compression of the right subclavian artery leading to congenital subclavian steal syndrome,,.Is the aorta on the left or right?
The aorta is the largest artery in the body. The aorta begins at the top of the left ventricle, the heart's muscular pumping chamber. The heart pumps blood from the left ventricle into the aorta through the aortic valve. Its small branches supply blood to the ribs and some chest structures.Is right aortic arch hereditary?
Persistent right aortic arch is a relatively common congenital birth defect often referred to as a “ring anomaly.” These are abnormalities in the major blood vessels at the base of the heart. While these abnormalities are inherited, the exact hereditary mechanism is unknown.What is aortic arch syndrome?
The aortic arch is the top part of the main artery carrying blood away from the heart. Aortic arch syndrome refers to a group of signs and symptoms associated with structural problems in the arteries that branch off the aortic arch.
