[The adventitia wrapping technique in microvascular surgery].
The success of microvascular anastomosis on fine vessels is essential not only for expanding the possibility of surgical treatment in such cases as replanting severed fingers of children, and vascularized nerve and joint grafting, but also for diminishing the damage to donors as well. This report describes the details of our study on a adventitia wrapping technique in which the adventitia was utilized for wrapping anastomosis. This study demonstrates that the advantages of the adventitia wrapping technique are as follows; (1) Adventitia wrapping technique provides a higher patency rate in smaller microvascular anastomosis. (2) Adventitia wrapping technique aids in reducing operative time and stitches. (3) Adventitia wrapping technique increases tolerable pressure of the anastomosis site and prevents aneurysm. (4) Immediate postoperative hemorrhage at the anastomosis site is lesser than that of the standard suture technique. These results indicate that this technique utilizes the tissue in site, therefore, is simple and useful for microvascular anastomoses.
