✦ Synopsis

This study was designed to clarify whether dryness of the vessel wall, especially of the intima, has any effect on thrombosis in microvascular anastomoses. The central artery of the ear of 30 rabbits was used as a model. The animals were divided into 3 groups of 10 each. In Group 1, each vessel was clamped and severed, the adventitia was removed, and the vessel ends were washed with heparinized saline (20 IU/ml). The vessel then was wrapped in gauze soaked with heparinized saline and allowed to sit for 60 minutes. Anastomosis of the vessel then was performed. In Group 2, the vessel underwent the same procedure, but was soaked with saline solution for 30 minutes and then left to dry for 30 minutes. In Group 3, the vessel was not soaked with the saline solution, but was left to dry for 60 minutes before anastomosis. Patency was checked 30 minutes after release of the clamps and 8 and 14 days after anastomosis. The patency rates were 100% (10/10) in Group 1, 80% (8/10) in Group 2, and 100% (10/10) in Group 3.
