[End-to-side anastomosis made with a short circulatory interruption in the receiving vessel. Experimental model in the rat].
End to side microsurgical anastomoses between vessels of small calibre require interruption of blood flow of about 25-40 min. In terminal vascular beds this time may be incompatible with the cellular survival. The authors refer their experience in rats with a partly original experimental technique requiring less time of clamping the receiving vessel (about 3-4 min), as the main part of the anastomosis is performed between the wall of the donor vessel and the adventitia of the receiving vessel, without interruption of blood flow in this latter. Histological examinations, performed 21 days later, reveal a patency rate of 60%.
