What is a aberrant artery?

Abstract. 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 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%).

What is aberrant Retroesophageal right subclavian artery?

An aberrant right subclavian artery (ARSA) is an anomaly with a reported incidence of 0.5% to 2%. Usually the aberrant artery follows a retroesophageal course; rarely it takes a course anterior to the esophagus or the trachea. The proximal aberrant artery was mobilized behind the esophagus.

What is aberrant anatomy?

(ab-er’ฤƒnt) 1. Wandering off; said of certain ducts, vessels, or nerves deviating from the normal course or pattern.

Is ARSA serious?

Most patients with ARSA are asymptomatic, but aneurysms in this location can cause serious compli- cations, such as distal embolization, rupture, and com- pression of neighboring structures [3]; therefore, its sur- gical treatment is crucial.

How serious is aberrant right subclavian artery?

The presence of an aberrant right subclavian artery poses a substantial risk of life-threatening hemorrhage in patients undergoing surgery like esophagectomy. Moreover, the recurrent laryngeal nerve does not follow the orthodox course, which is important in thyroid and parathyroid surgeries 6.

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.

How do you use aberrant in a sentence?

  2. When the astronomer looked into the telescope, he was shocked by the sight of a star moving in an aberrant path.
  3. If my aunt does not take her medication, she will have aberrant mood swings.

Can aberrant right subclavian artery be cured?

Aberrant right subclavian arteries are rare, but when present, can be accompanied by a Kommerell diverticulum, which requires intervention at > 3 cm in orificial diameter and > 5 cm in depth. When patients present with symptoms, they can be treated with both endovascular and open strategies.

How is an aberrant subclavian artery usually found?

Aberrant subclavian artery is a rare vascular anomaly that is present from birth. It usually causes no symptoms and is often discovered as an incidental finding (such as through a barium swallow or echocardiogram ).

What happens if the aberrant artery is dissected?

DISCUSSION. The injury to the aberrant artery will cause mediastinal hemorrhage or even arterioesophageal fistula in long-term. [ 7, 12] Dissecting and mobilization of esophagus through cervical or transhiatal routes might pose a great risk of injury and complication on the aberrant artery if the surgeon was not aware of it.

What happens if an aberrant artery passes through the esophagus?

Since the aberrant artery may pass the space between esophagus and vertebral column or the gap between esophagus and trachea in the midline, this anomaly may cause compression to the esophagus, which results in dysphagia.
