In 1960, Brecia and Cimino made arterialized veins by subcutaneous arteriovenous anastomosis and made subcutaneous arteriovenous fistula, which opened up the access for long-term dialysis. At present, chronic dialysis still uses radial arteriovenous fistula as the main access, and percutaneous femoral and subclavian veins and jugular veins have become the main access for induction dialysis and emergency dialysis. The ideal vascular access should have the following conditions: 1. The blood flow should reach 100-300 ml/min to ensure effective dialysis. 2.It can be used repeatedly, simple to operate, and has little impact on patients’ daily life. 3.Safe and less prone to thrombosis, infection, rupture, bleeding and other comorbidities, and light burden on the patient’s heart.
