ABSTRACT
PURPOSE:
To investigate the neovascularization after exposure of the external jugular venous endothelium in an experimental model.METHODS:
The sample was composed of 60 male rats of Wistar OUT B breed provided by animal colony of the Medicine College of Juazeiro do Norte, weighing 250 to 350g, aged 90-120 days. Randomized study in OUT B Wistar rats, open, with 60 days duration. The animals were distributed into three groups of 20 specimens and were subjected to the following Group 1 neck incision with dissection, ligation and section of the external jugular vein. Group 2 neck incision with dissection and ligation of the external jugular vein. Group 3 cervicotomy without dissection of the external jugular vein without ligation or section. The animals were sacrificed, half of them in 30 days and the other half within 60 days. The material in block harvested from the operated site were sectioned and stained for immunohistochemistry with CD34 marker.RESULTS:
Neovascularization occurred with level of significance when compared group 1 to group 3 at 30 days (p=0.0076) and the same occurred at 60 days (p=0.0001) (Newman-Keuls test).CONCLUSION:
The group with exposure of the venous endothelium showed a significant increase of neovascularization when compared with other groups.
