Comparison of clinical results between angioplasty balloon and venous angioplasty stent in dialysis dependent patients with upper extremity swelling due to venous hypertension following vascular access

Comparing the clinical outcomes between the endovascular balloon and stent methods in edema and upper extremity venous hypertension proceeding treatment via vascular access is an important subject to find a practical approach of modifying dialysis side effects, improve the quality of medical care, and increase the life span of patients. From ۲۰۱۶ to ۲۰۱۸, ۴۱ dialysis patients with central vein stenosis in Golestan Hospital of Ahvaz were randomly allocated into two groups: balloon angioplasty (۲۴ patients) and stent angioplasty (۱۷ patients). Patients were closely monitored in the ۱st, ۳rd, and ۶th months after angioplasty. Both groups underwent dialysis the following year. In this research, ۳۵ patients had upper left limb involvement (۸۵.۴%). The most common location of venous stenosis was the left brachiocephalic vein (innominate vein). Inflammation was mainly in the forearm and arm regions. There was a significant relationship in the therapeutic effect for reducing inflammation in each group (p<۰.۰۵), but the most remedial effects occurred in the first month after treatment. The primary patency and inflammation reduction in the ۳rd and ۶th month had been more in stent angiography. The difference between these two methods did not prove significant over a year according to their dialysis procedure. The present study results showed that the utilization of stent angioplasty is preferred over balloon angioplasty in the long term in patients suffering from edema and hypertension.
