A dialysis fistula bulge medically becomes an aneurysm and is treated differently depending on the size of the aneurysm, including localized bandaging for protection and surgical excision for repair to achieve elimination. If the same blood vessel is repeatedly punctured during dialysis treatment, a local aneurysm, also known as a dialysis fistula bulge, may form. In this regard, the number of punctures in the same blood vessel should be reduced. If the aneurysm diameter is <3cm or there is no risk of rupture, surgery is generally not needed, and the doctor should be cooperated with the local bandage treatment, i.e., elastic bandage protection. If the aneurysm is relatively large, i.e., the diameter is greater than 3cm, and at the same time there are symptoms of compression of nerves, other veins, and aneurysm infection, surgical resection is required to promote the repair of the vascular puncture site. For the case of dialysis fistula bulge, it is recommended to combine with the professional doctor's opinion, timely treatment in accordance with medical advice, so as to avoid delaying the condition.
