How serious is aberrant right subclavian artery?

Any unintentional injury of this artery during surgical procedures could be extremely life threatening. A 56-year-old woman presented with dysphagia, with concurrent aberrant subclavian artery and esophageal cancer.

What is aberrant right subclavian artery 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.

Is an 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.

How common 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.

What is the treatment for aberrant right subclavian artery?

Results. Treatment was performed as a hybrid procedure in eight patients. This included thoracic endoluminal graft exclusion with revascularization of the ASA, a pure endovascular procedure with two occluders in one patient, and an open procedure in one patient with ligation of the aberrant artery through a thoracotomy …

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].

What are the symptoms of an aberrant right subclavian artery?

The most commonly reported symptoms related to compression of adjacent structures by aberrant right subclavian artery (arteria lusoria) were dysphagia (71.2%), dyspnea (18.7%), retrosternal pain (17.0%), cough (7.6%), and weight loss greater than 10 kg over a 6-month period (5.9%).

How is ARSA diagnosed?

An ARSA was diagnosed when this vessel was not seen in the normal position and an arterial vessel was seen crossing behind the trachea towards the right arm, arising as a fourth branch of the aortic arch, at a lower level than normal.

Is ARSA life-threatening?

ARSA-esophageal fistula is a rare sequela that can present with a life-threatening upper gastrointestinal (GI) bleed. Case Report: We report the case of an 88-year-old male who presented with signs of upper GI bleeding.

Is ARSA treatable?

Conclusions: Complete anatomical repair of the ARSA aneurysm could be performed through the combination of the supraclavicular approach and the left posterolateral thoracotomy, with excellent results. Exclusion of the ARSA aneurysm without revascularization resulted in a suboptimal outcome.

What is hanuld aberrant right subclavian artery?

Aberrant right subclavian artery is a rare phenomenon, but also the most common abnormality of the aortic arch. Hanuld was first described this arterial anomaly in 1735, but its symptomatic form was first described by Bayford in 1787 as the term of “dysphagia lusoria” or the freak of nature in patients with dysphagia.

What is the origin of the right subclavian artery?

Essentially, right subclavian artery originates from the brachiocephalic artery, but in 0.4-1.8% of the general population it may arise directly from the aortic arch distal to the left subclavian artery.[1,2,3] ARSA on its way to the right arm crosses the midline posterior to esophagus.

What are the signs and symptoms of subclavian artery anomaly in children?

Swallowing symptoms in children may present as feeding difficulty and/or recurrent respiratory tract infection. When aberrant subclavian artery causes no symptoms, treatment is not needed. If the anomaly is causing significant symptoms, treatment may involve surgery.

What happens if the subclavian artery is damaged during surgery?

Any unintentional injury of this artery during surgical procedures could be extremely life threatening. A 56-year-old woman presented with dysphagia, with concurrent aberrant subclavian artery and esophageal cancer.
