IPCCC Term ABERRANT ORIGIN OF LEFT SUBCLAVIAN ARTERY
IPCCC Code 09.30.04
ICD-11 Code PENDING
IPCCC Definition A congenital cardiovascular malformation in which the left subclavian artery arises distal to the right subclavian artery in the setting of a right arch.
This superior view of the arterial trunks in this heart with concordant ventriculo-arterial connections demonstrates a right aortic arch with mirror image branching of the brachiocephalic arteries and distal origin of the left subclavian artery. Note the left arterial extending from the left subclavian artery to the pulmonary trunk, encircling the trachea (yellow star) and esophagus (red star). The proximal part of the aberrant left subclavian artery represents the distal remnant of the left aortic arch and is typically referred to as the diverticulum of Kommerell.
