We have studied the vasa vasorum of the human thoracic aorta using a polyester resin casting technique, coupled with the tissue clearing method of Spalteholz. We found that the vasa vasorum originated from intercostal arteries. They ramified and formed networks within the aortic adventitia and the outer layers of the media. Venous networks were identified in the adventitia as wall. In addition to being a usefull research tool, the methodology utilized in this study produces specimens that can be used in teaching vascular anatomy to medical students.
