[Vascular microanastomosis by eversion and stapling using VCS forceps. Presentation of the technique and experimental evaluation of its reliability].

With the objective of further improving the reliability of microvascular anastomoses, several different procedures are now available to microsurgeons, including eversion-stapling by VCS forceps. The authors start by presenting the technique, emphasizing the need for specific instruments and compliance with certain principles determining the success of these anastomoses. In the context of an experimental protocol in the pig, on vessels measuring an average of 2.5 mm in diameter, 80 anastomoses were performed by VCS stapling-eversion and studied clinically, histologically and ultrastructurally, comparing the results to those of conventional anastomoses by approximation-suture with needle and suture. In light of the results, eversion-stapling anastomoses appear to be more reliable due to the absence of intraluminal foreign body, permanent endothelial continuity and effective re-endothelialisation before day 7.
