Inclusion criteria

Inclusion criteria: The following are the guidelines for PTA: vascular diameter of the shoulder radial vein is less than 2.5 mm, brachial artery blood flow is less than 400 ml/min, and RI is greater than 0.60. Other clinical symptoms include prolonged hemostasis time during dialysis of 20 minutes or more, elevated venous pressure of 180 mmHg or more, or enlarged shunt varices or elevated shunt pressure on examination. PTA was indicated when clinical symptoms included prolonged hemostatic time on dialysis of 20 minutes or more, elevated venous pressure of 180 mmHg or more, or enlarged shunt varices or elevated shunt pressure on examination.

Exclusion criteria

Exclusion criteria: Patients will be excluded from the study if they meet any of the following criteria 1.Patients who underwent stenting during PTA 2.Cases in which the patient died or did not receive medical attention and the progress could not be confirmed 3.Other patients who were judged to be inappropriate for inclusion in the study by the physician.

Design outcomes

Primary

MeasureTime frame
This study compared the duration of lesion patency among hemodialysis patients who underwent PTA for CAS, grouping them into a non-compliance balloon (NCB) group, a drug-coated balloon (DCB) group, and a peripheral cutting balloon (PCB) group based on the devices used.

Secondary

MeasureTime frame
As secondary endpoints, we evaluated the primary patency rates at the lesion site at 90 and 180 days postoperatively. We also examined the factors that influenced the patency rate at 120 days.
