The purpose of this study is to assess whether it is possible to improve the healing process after vascular microsurgery by using a cuff of lyophilized heterologous collagen. This should act as a biological support to improve healing in arterial microanastomoses. This study, on experimental animals, involved the preparation of aortic termino-terminal anastomoses. Histological studies were made 7, 14, 28 and 60 days postoperatively. Preliminary results seem to exclude that collagen significantly helps vascular repair in vascular microsurgery.

Abstract
The purpose of this study is to assess whether it is possible to improve the healing process after vascular microsurgery by using a cuff of lyophilized heterologous collagen. This should act as a biological support to improve healing in arterial microanastomoses. This study, on experimental animals, involved the preparation of aortic termino-terminal anastomoses. Histological studies were made 7, 14, 28 and 60 days postoperatively. Preliminary results seem to exclude that collagen significantly helps vascular repair in vascular microsurgery.
