Objective: To carry out a 3D vector reconstruction of the nerves of the ventral region of the neck from anatomical sections of the “Korean Visible Human” for educational purposes. Materials and Methods: The anatomical subject was a 33-year-old Korean man who died of leukemia. He was 164cm tall and weighed 55kgs. A cryomacrotome sectioned the frozen body into 5960 sections. Sections numbered 1500 to 2000 were used for this study. A segmentation by manual contouring of each nervous anatomical element of the ventral region of the neck was done using Winsurf version 3.5 software on a laptop PC running Windows 10 equipped with an 8 gigabyte RAM. Results: Our vector 3D model of nerves in the ventral neck region includes the brachial plexuses, vagus nerves, inferior and superior laryngeal nerves, glossopharyngeal nerves, hypoglossal nerves and spinal nerves. This vector model has been integrated into the Diva3d virtual dissection table. It was also uploaded to the Sketchfab website and 3D printed using an ENDER 3 printer. Conclusion: Our 3D reconstruction of the nerves of the ventral region of the neck is an educational tool for learning the nerves of the ventral region of the neck and can also serve as a 3D atlas for simulation purposes for training in therapeutic gestures.

The birth defect of the right coronary artery from the aorta is an anatomical malformation characterized by the abnormal birth of the right coronary artery from the antero-left sinus. It has an abnormal initial path between the aorta and the pulmonary artery and is most often intramural in the aortic wall. It represents 0.1 to 0.3% of the population and exposes to a high risk of sudden death on exertion. The mechanism retained for sudden death is the occurrence of stress myocardial ischemia by compression of the abnormal artery between the two large vessels. The diagnosis can be confirmed by a careful echocardiographic examination. The coronarography confirms the diagnosis. Surgical treatment presents a very low risk and eliminates the risk of stress myocardial ischemia. It therefore appears necessary to look for this anatomical anomaly systematically, at least in all young adults who engage in intense sports activities.
