PURPOSE: This paper proposes a model of training surgical skills using vascular anastomosis in an animal model that simulates the size, consistency and resistance arteries and veins, to use it to chicken trachea and esophagus, respectively. METHODS: We used chicken necks where the esophagus and trachea were dissected and after preparation were followed every step of the procedure of vascular anastomosis. The flow of the anastomosis was confirmed by direct observation and testing of filling (empty-and-refill test) immediately after the anastomosis. RESULTS: All samples proved to be viable by the criteria described above. CONCLUSION: For the first time presents an interesting experimental model used to train vascular sutures, because it is endowed with all the necessary requirements for the learning of experimental vascular surgery.

Mammalian endothelial cells lining hepatic sinusoids have been found to be widely fenestrated. Previous SEM studies (1,2) have noted two general size catagories of fenestrations; large fenestrae were distributed randomly while the small type occurred in groups. These investigations also reported that large fenestrae were more numerous and larger in the endothelial cells at the afferent ends of sinusoids or around the portal areas, whereas small fenestrae were more numerous around the centrilobular portion of the hepatic lobule. It has been further suggested that under some physiologic conditions small fenestrae could fuse and subsequently become the large type, but this is, as yet, unproven.We have used a reproducible experimental model of hypoxia to study the ultrastructural alterations in sinusoidal endothelial fenestrations in order to investigate the origin of occurrence of large fenestrae.
