The intimal healing of microvascular anastomoses.

Examination with the S.E.M. shows that 5 days after surgery the microanastomoses area is covered with pseudointima, and the regeneration of the intima is completed within two weeks. Comparing the two different suture techniques (large bites and small bites), there are no differences between them in the resultant patency rates. The large bites produce less immediate leakages. There were no significant differences in the process of intimal healing.
