Is Arsa related to Down syndrome?
The meta-analysis showed that ARSA is a significant risk factor for Down syndrome (pooled LR+ = 26.93, 95% CI, 19.36-37.47, P for effect < 0.001, P for Q = 0.3, I(2) = 17.3%), whereas normal RSA is a significant protective marker (pooled LR- = 0.71, 95% CI, 0.51-0.99, P for effect = 0.043, P for Q = 0.9, I(2) = 0%).
Is aberrant right subclavian artery a 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 …
What does aberrant right subclavian artery mean?
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.
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 aberrant right subclavian artery hereditary?
Although the diagnosis of an aberrant right subclavian artery is beginning to be used as a sonographic marker of aneuploidy and congenital heart defects, the etiology of this vascular abnormality could be related to genetic disorders.
What is ARSA baby?
Introduction. 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.
Is aberrant right subclavian artery genetic?
What causes Arsa?
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.
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.
Is ARSA treatable?
The present case shows that an ARSA aneurysm with the appropriate anatomy can be successfully treated with a Zenith iliac plug combined with surgical ligation for aneurysm exclusion.
How is aberrant subclavian artery treated?
A muscle-sparing right thoracotomy was used in the pediatric patients, and a supraclavicular approach was used in the adult. Patients were treated successfully by division of the aberrant right subclavian artery and translocation to the right common carotid artery, without graft interposition.
What does the right subclavian artery do?
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.
