What is ARSA in fetus?

Aberrant right subclavian artery (ARSA) is the most common congenital abnormality of the aortic arch [1-6]. In ARSA, the right aortic arch regresses between the right common carotid and right subclavian arteries, instead of being distal to them.

Does aberrant right subclavian artery need to be treated?

Aberrant right subclavian artery (RSA) is a rare congenital anomaly that usually does not produce symptoms. Symptomatic patients require surgical intervention.

What causes an 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].

Is aberrant right subclavian artery a congenital heart defect?

Aberrant right subclavian artery, also known as arteria lusoria, is one of the rarer congenital vascular malformations of the left sided aortic arch which arises distal to the left subclavian artery, following a retroesophageal course to the right side causing compression of the trachea or esophagus and resulting in a …

Is aberrant right subclavian artery life threatening?

Aberrant Right Subclavian Artery: A Life-threatening Anomaly that should be considered during Esophagectomy.

How rare is aberrant right subclavian artery?

Aberrant right subclavian artery (also known as Arteria Lusoria) is the most common congenital anomaly of the aortic arch occurring in 0.5% to 1.8% of the population based on cadaveric studies.

Is ARSA life threatening?

ARSA-esophageal fistula is an uncommon and potentially fatal cause of GI bleeding.

How many people have an aberrant right subclavian artery?

The right subclavian artery has an aberrant origin in 0.5% to 1% of the population. 1, 2, 3 Presence of associated symptoms is, however, even more uncommon. The most common symptoms include dysphagia, cough, and stridor, which are usually associated with evident compression of the appropriate structure.

Can you live with ARSA?

Abstract. An aberrant right subclavian artery (ARSA) is the most common aortic arch anomaly, but only 19 previous cases of ARSA-esophageal fistula have been reported. Six patients have survived their bleeding episode. We describe the case of a 44-year-old woman who developed massive hemoptysis.

Is ARSA hereditary?

There seems to be a genetic component in ARSA. Genetic counseling can help to determine your individual risk of recurrence, which depends on whether a cause for the ARSA was found in the first place as well as your age and other factors.
