A microsurgical technique for the creation of arteriovenous fistulas.

A new method for creating arteriovenous fistulas employing microvascular techniques is described. It is proposed that this method should be used in problem cases where conventional means have failed or as a first procedure in cases in which technical problems are envisaged. A two-stage microvascular procedure has been used to create adequate fistulas in these difficult cases. Satisfactory fistulas have been formed in 15 out of 16 patients in whom these techniques have been used.
