Clipado parcial de vaso receptor asociado a sutura microvascular: modelo experimental en ratas

Objetive: to determine the possibility of partial clamping and maintaining small arteries flow within a modified clip. To perform an end to side anastomosis in an artery partially clamped and demonstrate its permeability. Method: partial carotid clamping in rats and intraluminal flow measurement. End to side anastomosis suture of the vessels clamped. Histopathologic study of the brains. Results: the persistence of flow during partial clamping of the vessel. Anastomosis remained permeable after the procedures. Eas confirmed no signs of ischemia in brains fixed were reported. Conclusion: this modification in the clip allows an end to side anastomosis with partial clamping of the recipient vessel, keeping the flow within in, in small vessels.(AU)
