A unilateral, left-sided aberrant origin of the long thoracic nerve
Background
Variations in the roots of the brachial plexus and their branches may cause unexpected complications during surgical procedures of the neck. In this report, we show an extremely rare variation of the long thoracic nerve.
Methods
During routine dissection of the posterior triangle of the neck in a white female cadaver, a variation in a branch of the brachial plexus was observed and documented. Further dissection of the axilla and anterolateral thoracic wall were performed to follow the course of the anomalous superficial nerve.
Results
The abnormal nerve was discovered to be a variation of the long thoracic nerve (LTN) formed from a supraclavicular union of only the C6 and C7 spinal nerve roots.
Conclusions
Variations in the anatomy of the brachial plexus are not uncommon, but variations of the LTN are rare. Awareness of the LTN in relation to the brachial plexus is useful for the head and neck surgeon operating in less often encountered spaces to prevent injury.
期刊介绍:
Translational Research in Anatomy is an international peer-reviewed and open access journal that publishes high-quality original papers. Focusing on translational research, the journal aims to disseminate the knowledge that is gained in the basic science of anatomy and to apply it to the diagnosis and treatment of human pathology in order to improve individual patient well-being. Topics published in Translational Research in Anatomy include anatomy in all of its aspects, especially those that have application to other scientific disciplines including the health sciences: • gross anatomy • neuroanatomy • histology • immunohistochemistry • comparative anatomy • embryology • molecular biology • microscopic anatomy • forensics • imaging/radiology • medical education Priority will be given to studies that clearly articulate their relevance to the broader aspects of anatomy and how they can impact patient care.Strengthening the ties between morphological research and medicine will foster collaboration between anatomists and physicians. Therefore, Translational Research in Anatomy will serve as a platform for communication and understanding between the disciplines of anatomy and medicine and will aid in the dissemination of anatomical research. The journal accepts the following article types: 1. Review articles 2. Original research papers 3. New state-of-the-art methods of research in the field of anatomy including imaging, dissection methods, medical devices and quantitation 4. Education papers (teaching technologies/methods in medical education in anatomy) 5. Commentaries 6. Letters to the Editor 7. Selected conference papers 8. Case Reports
