Abstract
Principles of microvascular anastomotic surgery are uncertain in contrast to the standardized suture methods for the repair of large arteries. Complications of early thromboses or late stricture at the microvascular anastomotic line can be related to the inherent biologic response of these delicate tissues to penetrating needle and suture. A new method for microvascular reconstruction based on the principle of flanged, nonpenetrated, intimal approximation by an arcuate-legged clip has proven biologically and technically superior to the penetrating microsuture. These conclusions are based on extensive testing in multiple surgical laboratories of the following parameters: long- and short-term patency, morphology of wound repair, and burst and tensile strength. Details of the new surgical system and experimental studies are described.
