Vascular capstone course
Welcome to the Emory vascular capstone course. The following links will help you get access to the cases you need to scroll through the course and give you some additional information.
Normal case
This is a case of a 30-year-old woman with a cervical spine fracture after trauma. Because of the extent of injuries, she underwent a CT angiogram to assess her vascular structures. In this case, the vasculature of her neck is normal. Use this case to practice your search through the vessels of the head and neck for injury.
