RESUMO
We report on a very rare case of co-existence of os acromiale with suprascapular osseous bridge in a dry scapula. The frequency of os acromiale alone ranges from 1.3 to 15%, while the frequency of suprascapular osseous bridge varies between 0.036% and 12.5%. We review the relative literature and emphasize the fact that such knowledge is important for a physician in order to avoid misdiagnosis of an acromion fracture and lytic lesion of the scapula.

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.

A technique to prepare casts of the renal vessels using unsaturated polyester resin solutions is described. The dimensions, morphology and relations of the vessels are very well represented by the casts. The methods is economical and easy to apply and the casts can be used for both teaching and pathologic research.
