High patency rate of internal arteriovenous fistulae in non-uremic patients with normal veins.
Forearm arteriovenous (AV) fistulae were formed in seventeen patients with normal coagulation parameters as part of a controlled study of the effects of hemodialysis in schizophrenia. The 100% patency rate of AV fistulae in this group of patients compares favorably with the patency rates obtained with similar AV fistulae in renal failure patients, and it is significantly higher than the patency rates obtained for AV fistulae formed to improve venous access in patients with acute leukemia. The results suggest that uremic coagulopathy contributes little to the success of internal AV fistulae. Adequacy of forearm veins is thought to be of greater importance.
