A New Surgical Approach to the Management of Symptomatic Aberrant Right Subclavian Artery

Anomalous Right Subclavian Artery-Esophageal Fistulae

“…In most cases, esophagoscopy cannot be used to assist in diagnosis of acute hemorrhage because of the extreme volume of hematemesis [ 3 ]. Upper endoscopy has been used in six reported cases and was able to identify the source of bleeding in only three patients [ 11 – 13 ]. This is comparable to the sensitivity of EGD in diagnosing artery-esophageal fistulas of 38% [ 11 ].…”

Aneurysms of an aberrant right subclavian artery: Report of two cases

“…An ARSA is the most common arch anomaly with an incidence of 0.5–0.8% in the general population 1 . It results from the regression of the right fourth arch between the carotid and subclavian artery.…”

“…It results from the regression of the right fourth arch between the carotid and subclavian artery. The ARSA persists as a branch of the descending thoracic aorta and courses upwards and towards the right, behind the trachea and the oesophagus in 80% of cases, in between the two in 15% of cases, and anterior to the trachea in 5% of cases 1 . The pathology produced by ARSA was first described as dysphagia lusoria or ‘sport of nature’ by Bayford in 1794.…”

A retroesophageal right subclavian artery with the right vertebral artery originating from the right common carotid artery

“…In the newborn and infants the esophagus and trachea may be distorted and surgical treatment becomes necessary (Arciniegas, 1979;Binet and Langlois, 1977;Lam et al, 1978;McFaul et al, 1981;Richardson et al, 1981). On the other hand the dysphagia may be initially noticed in later years due to vascular arteriosclerotic changes and aneurysmal dilatation of Kommerell's diverticulum (Kalke et al, 1987;Lam et al, 1978;Lazar et al, 1987;Lemire et al, 1977;McIntyre and Lynn, 1980;Richardson et al, 1981).…”
