J. Neuroradiol.2006 Mar 01; 27 AB - SUMMARY: We report the case of a 1\batchmode \documentclass[fleqn,10pt,legalpaper]{article} \usepackage{amssymb} \usepackage{amsfonts} \usepackage{amsmath} \pagestyle{empty} \begin{document} \(\frac{1}{2}\) \end{document}-year-old female child, who developed symptomatic hemorrhage from major aorto-pulmonary collaterals after surgery for Tetrology of Fallot. During the course of embolization of the aorto-pulmonary collaterals, we discovered the presence of direct origin of the left internal and external carotid arteries from the aortic arch. Further, there was cervical origin of right subclavian artery. We discuss the clinical significance and potential embryological mechanism in development of this anomaly.
