In general, arteriovenous endovascular fistulae are used by puncture after 8 to 12 weeks of maturity, and in young people they can be applied at 4 weeks after surgery, after which they can be placed in a tube for dialysis if emergency dialysis is needed. When end-stage renal disease, some patients need hemodialysis treatment, which requires the establishment of vascular access to ensure adequate blood flow through the dialysis machine. The usual surgical methods include direct anastomosis of the autologous arteries and veins and arteriovenous bypass grafting with autologous or artificial blood vessel grafts, with autologous arteriovenous fistulae being the preferred choice, and radial artery-cephalic vein end-to-end anastomosis at the wrist is often chosen to provide vascular access for hemodialysis for long term and effective extracorporeal circulation. Regardless of the surgical method, there will be damage to the blood vessels, requiring a period of recovery, and after arteriovenous fistula surgery, the physiological blood circulation is modified, and the body needs a period of time to be suitable for the new circulatory pattern, which is usually used after 8 to 12 weeks of postoperative maturation. Young people can start to apply 4 weeks after surgery. Prior to this time, if emergency dialysis is needed, tubing can be placed for dialysis. Arteriovenous endovascular fistula is the lifeline of dialysis patients, if there is any abnormality, such as vasovagal tremor weakening, etc., you need to consult the hospital in a timely manner, and improve the examination and treatment under the guidance of the doctor.
