A new variant of aberrant left brachiocephalic trunk in mam: case report and literature review
Folia Morphol 2005;64(1):47-50.
Abstract
Importance is placed on aberrant arteries in the radiological and surgical literature.
A normal left brachiocephalic trunk is characteristic for the right aortic arch.
However, an aberrant left brachiocephalic trunk arising as the last branch of the
aortic arch on the left side has not yet been described in the literature. Described
here is a new variant of the retro-oesophageal aberrant left brachiocephalic trunk,
occasionally observed in a patient during diagnostic investigation or surgical treatment
for steno-obstructive involvement of the carotid district. The triple anomaly
of the left aortic arch consisted of: 1. the presence of a hypoplastic left brachiocephalic
trunk behind the oesophagus, 2. the absence of a brachiocephalic trunk
on the right side and 3. separate origins of the arteries on the right side, with the
right common artery preceding the right subclavian artery. In front of the trachea
an 8-mm prosthetic PTFE was implanted from the proximal segment of the right
subclavian artery to the junction of the left common carotid and left subclavian
arteries. The author demonstrates the inadequacy of auxiliary investigations to
detect aberrant arteries, which may only be identified precisely intra-operatively.
