Dialysis arm bulge in kidney disease patients is mostly considered to be caused by aneurysm, if the local aneurysm is relatively small, no need to deal with. If the local aneurysm is small, there is no need to deal with it. If the aneurysm is big, then it needs to be treated by surgery. If there is aneurysm in the arm of dialysis patients with kidney disease, there will be localized bulging symptoms, if the localized bulging is relatively small, you can not take measures to treat it. If the local aneurysm is relatively large, it can be treated by aneurysm resection, revascularization, intra-aneurysm repair. In addition, patients usually need to keep the local skin clean and dry during dialysis, and should not repeat the puncture in the same area, and if the local puncture occurs after the need for timely compression to stop bleeding, to prevent the local endocardial fistula blockage. It is recommended that dialysis patients with kidney disease need to seek medical treatment from regular hospitals in time when arm bulge occurs during dialysis, and the doctor will choose appropriate measures to treat the patient’s condition.
