Endovascular fistula, or arteriovenous endovascular fistula, is a technique in which the superficial arteries of a limb are anastomosed directly to the veins, mainly for hemodialysis. Arteriovenous endovascular fistula is suitable for patients with renal insufficiency who need long-term hemodialysis. Through arteriovenous endovascular fistula, a new blood channel can be established, so that the blood flow in the vein can be increased, which is conducive to puncture for dialysis treatment. As the lifeline of dialysis, arteriovenous endovascular fistula can greatly improve the quality of life of patients. The specific use of arteriovenous endovascular fistula is recommended to consult a professional doctor, the patient in the process of arteriovenous endovascular fistula surgery or any discomfort after surgery, should promptly inform the doctor so as to carry out the appropriate treatment. Patients who need to perform endovascular fistula are recommended to consult a regular hospital in time and follow the doctor’s instructions for standardized treatment.
