What causes diverticulum of Kommerell?

What causes diverticulum of Kommerell?

Kommerell diverticulum, a remnant of the left dorsal arch, is located where the left aberrant subclavian artery originates, causing external posterior compression of the esophagus. Patients often become symptomatic in later decades as the arteries become tortuous and aneurismal.

Is Kommerell diverticulum an aneurysm?

Kommerell’s diverticulum refers to the aneurysmal dilatation of the descending aorta at the origin of an aberrant subclavian artery, which is seen in both right- and left-sided aortic arches.

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.

Is a right aortic arch a heart defect?

Right aortic arch anomalies occur in 0.01 to 0.1% of the general population. Abnormalities of aortic arch branching and orientation are associated with a variety of congenital heart defects (tetralogy of Fallot and truncus arteriosus), as well as chromosomal abnormalities, such as DiGeorge syndrome (22q11 deletion).

Does it hurt to walk with diverticulitis?

cramping. constipation, diarrhea, or other change in bowel habits. rectal bleeding. sharp pain with breathing or jarring movements such as walking.

Can diverticulitis cause breathing problems?

In such cases, its manifestation can be presented with various conditions, including thrombophlebitis of the leg, inguinal abscess, hip and buttock pain, subcutaneous emphysema, and shortness of breath [1,3-6].

What is a Kommerell aneurysm?

Kommerell aneurysm is an outpouching from a kommerell diverticulum. • Mimics include saccular aneurysm of the thoracic aorta, ductus diverticulum and dilated Kommerell diverticulum. • Kommerell aneurysm has the tendency to rupture, therefore, accurate diagnosis is critical.

What is a double aortic arch?

Double aortic arch is an abnormal formation of the aorta, the large artery that carries blood from the heart to the rest of the body. It is a congenital problem, which means that it is present at birth.

What causes right aortic arch?

Right aortic arch occurs due to the persistence of the right branch with the regression of the left branch. This means that the aorta arches to the right side. It is most commonly a normal variant.

What is vascular ring?

A vascular ring is a malformation of the aortic arch anatomy, where vessels partly or completely encircle the trachea and esophagus. A normal heart with a normal aortic arch is shown on the left. An example of a vascular ring — a double aortic arch — is shown on the right.

What causes a right sided aortic arch?

The causes of right-sided aortic arch are still unknown, 22q11 deletions have been found in some people with this condition. It has also been found in association with other genetic syndromes such as Trisomy 21 (Down syndrome).

Which side should aortic arch be on?

The aorta forms an arch in the chest and usually travels inside the chest on the left side. In some people the arch of the aorta turns to the right and travels down the chest on the right side. This is known as a right aortic arch.

Can a right aortic arch with Kommerell’s Diverticulum rupture?

Right aortic arch with Kommerell’s diverticulum (KD) is a very rare situation. Most patients with KD are asymptomatic; however the most serious issue in the course of aneurysm is its marked propensity towards rupture and dissection [1, 2]. As per earlier reports, all the patients who presented with rupture has died [1].

What is the origin of the Kommerell Diverticulum?

Kommerell diverticulum. It usually refers to the bulbous configuration of the origin of an aberrant left subclavian artery in the setting of a right-sided aortic arch. However, it was originally described as a diverticular outpouching at the origin of an aberrant right subclavian artery with a left-sided aortic arch.

Is the left side of the aortic arch dilated?

Right aortic arch and the aberrant origin of the left subclavian artery, which passes anterior to the esophagus, is dilated (Diverticulum of Kommerell). A Kommerell diverticulum refers to the bulbous configuration of the origin of an aberrant left subclavian artery in the setting of a right-sided aortic arch.

How big is the right side of Kommerell’s aneurysm?

Magnetic resonance angiography and an arch angiogram confirmed the presence of a right-sided aortic arch, an occluded aberrant left subclavian artery, and the presence of a Kommerell’s aneurysm measuring 3 cm ( Fig 1, B ). Fig 1. Case 1.
