In uremic hemodialysis patients, vascular access becomes the lifeline of the patient. It is wise to go to a specialized hospital early to establish an arteriovenous endovascular fistula. For various reasons, most patients enter dialysis without long-term hemodialysis vascular access and need to establish temporary vascular access, i.e., deep vein placement, which is risky and not to mention the fact that our department often encounters swelling of the limbs after the establishment of endovascular fistula due to infection and thrombosis caused by the placement of the tube, and if the internal jugular vein placement leads to obstruction of the superior vena cava, it will directly lead to the temporary inability to establish endovascular fistula in the upper limbs, and the patient will suffer a lot. The patient will suffer a lot of pain and cost. Therefore, if the creatinine of a patient with chronic renal insufficiency rises to about 400-500, although there are no obvious symptoms, it is advisable to consider establishing an arteriovenous endovascular fistula if peritoneal dialysis is not considered, which will significantly improve the patient’s quality of life.
