Background

Autologous arteriovenous fistula is one of the vascular access for hemodialysis treatment of patients with End-Stage Renal Disease (ESRD, i.e., uremia). While vascular access is the route by which blood from a patient is continuously drawn outside the body and returned back to the body. The self-body arteriovenous internal fistula forming technology is that a certain artery with close distance is communicated with a superficial vein vessel under the skin through operation to artificially form a straight-through pipeline between the arteriovenous in the body; aiming at utilizing the advantage of the superficial vein that the puncture is convenient; on the other hand, blood is directly supplied through the artery, so that the superficial vein blood flow is increased to meet the treatment requirement. The autoarteriovenous fistula has been widely accepted as the first blood vessel access for patients with uremia to receive maintenance hemodialysis treatment, and has obvious advantages compared with other types of access (such as central venous catheterization, artificial blood vessel and the like), such as: 1. the incidence of stenosis is low; 2. the thrombosis rate is low; 3. can puncture repeatedly and heal automatically, and has low infection incidence; 4. has less complication and long service life.
