چکیده
We report the case of a 1 1/2-year-old female child, who developed symptomatic hemorrhage from major aorto-pulmonary collaterals after surgery for Tetralogy 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.

The Case Report of Variation in Subclavian Branches
The Subclavian artery is a major branch of the Aorta. In the left the subclavian artery arises from aortic arch, and in the right it arises from the Brachiocephalic trunk This artery passes from the subclavian groove on the first rib and continues as Axillary artery. The Subclavian artery has several branches that supply chest wall, Thyroid gland and cervical region. Several variations about th...
متن کاملAnatomical Variations of Vertebral Artery
Introduction: Vertebral arteries arise from the root of the neck as the first branches from the superior-posterior aspect of the subclavian arteries. They ascend the neck to enter the cranial cavity and supply blood to the brain. Methods: A total of 20 cadavers (in 10 years) were dissected for the study of variations in the origin of the vertebral artery. This study was conducte...
متن کاملAnatomical Study of Subclavian Artery and Its Branches
Background: The branches of right and left subclavian arteries are important in conducting of blood to spinal cord, posterior cranial fossa, base of the neck, thyroid gland, wall of the thorax and abdomen. The routine use of internal thoracic artery as a conduit in coronary artery bypass grafting surgery requires appreciation of the anatomical variations of these vessels. So far, there is not a...
متن کاملA unique case of right cervical aortic arch with anomalous left common carotid artery and absent right common carotid artery
INTRODUCTION Cervical aortic arch is a rare anomaly where-in the ascending aorta arises normally from the left ventricle and extends in such a fashion that the aortic arch is situated high in the neck on either side. This anomaly should be suspected in any child exhibiting a pulsatile swelling in the neck. CASE COMMENTARY An 8 year old child presented with a pulsatile swelling on the right si...
متن کاملA Case Report of Variant Origin of Left Vertebral Artery from Aortic Arch and its Embryological Explanation
Vertebral artery is the first branch of subclavian artery. It merges with the same artery of the opposite side to form basilar artery and becomes one of the important source of blood supply to the brain. Variation in the origin of left vertebral artery was found in 65 year old female during magnetic resonance angiography of the neck vessels. It originated from aortic arch and was longer as ...
