Common Trunk Origin of the Brachiocephalic and Left Common Carotid Arteries from the Aortic Arch
ثبت نشده
چکیده
The arch of the aorta lies in the superior mediastinum and extends from the level of the second right sternocostal joint and ascends diagonally and to the left anterior to the trachea and descends to the left of the fourth thoracic vertebral body continuing as the descending thoracic aorta [1]. The arch of the aorta normally gives rise to three branches namely the brachiocephalic, left common carotid and left subclavian arteries. This is the most common pattern occurring in about 65-75% of the population [1-6].

Anatomical Variations in the Branching Pattern of Human Aortic Arch: A Cadaveric Study from Central India
Variations of the branches of aortic arch are due to alteration in the development of certain branchial arch arteries during embryonic period. Knowledge of these variations is important during aortic instrumentation, thoracic, and neck surgeries. In the present study we observed these variations in fifty-two cadavers from Indian populations. In thirty-three (63.5%) cadavers, the aortic arch sho...

Absolute contraindications to percutaneous tracheostomy due to anomaly of aortic arch branches origin and running A 77-year-old patient required percutaneous tracheost-omy. A first clinical evaluation showed a pulsating mass in the suprasternal region. Computed tomography (CT) revealed the presence of anomaly of the aortic arch branches (Fig. 1). We did not perform any type of tracheostomy due ...

In this study, the aim was to investigate the anatomy of the aortic arch arteries in mole-rats (Spalax leucodon). Six adult mole-rats were used for this purpose. Coloured latex was injected into the left ventriculus of the hearts of all animals. The materials were carefully dissected and the arterial patterns of arteries originating from the aortic arch were examined. The brachiocephalic trunk,...

The variant anatomy of the branches of the aortic arch is of profound surgical relevance. Altered course of these arteries, if unsuspected, could lead to accidental injury to these vessels and subsequent hemorrhage. During routine dissection of a sixty-five year old female cadaver of Indian origin, we observed a rare compendium of vascular variations in the anterior cervical region. These inclu...

The variations in the aortic arch and its branches are of surgical interest. Many anomalies of the aortic arch and great vessels are uncovered as serendipitous findings on imaging studies, in the anatomy laboratory, or at surgery. A 56-year-old woman had an arch angiogram as part of an evaluation for cardiovascular disease. A two-vessel left aortic arch was identified consisting of the brachioc...
