Expansion of the venous outflow tract in arteriovenous grafts of the forearm using antebrachial venoplasty.

The use of venoplasty to widen the antecubital venous outflow during the placement of arterio-venous grafts in the forearm for angioaccess is described. This has allowed an increased use of grafts for the forearm for angioaccess in instances in which antecubital veins were otherwise believed to be inadequate in size. Expansion of the venous outflow tract may also increase the long term patency of these grafts.
