Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this clinical trial is to compare the efficacy and safety of cutting balloons versus drug-coated balloons in treating venous stenosis of autologous arteriovenous fistulas.The main questions it aims to answer are:

1. Will drug-coated balloons achieve a better CD-TLR rate compared to cutting balloons?
2. What medical problems do participants have when receiving treatment with drug-coated balloons or cutting balloons?

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study will recruit 180 patients with venous segment stenosis of autologous arteriovenous fistulas at multiple centers from June 2024 to December 2025. Patients will be divided into two cohorts based on the treatment method: the Cutting Balloon group and the Drug-Coated Balloon group. The primary outcomes observed will be the primary patency rates of the target lesion at 1, 3, 6, and 12 months post-operation, re-intervention rates of the target vessel, and the technical success rates and procedural success rates of the two devices, along with major adverse events during the perioperative period.

Interventions

Learn about the drugs, procedures, or behavioral strategies being tested and how they are applied within this trial.

Endovascular therapy

Endovascular therapy is a minimally invasive interventional approach that utilizes the vascular system as a pathway to access and treat various pathological conditions within the body. By employing specialized catheters and devices, endovascular techniques enable precise delivery of therapeutic agents or interventional procedures directly to the target site, without the need for conventional open surgery.

Intervention Type PROCEDURE

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

Subjects aged between 18 and 75 years. Subjects possess a mature upper limb autologous arteriovenous fistula (AVF) and have undergone at least one hemodialysis session.

Target lesion must be located in the venous segment of the upper limb AVF. Doppler ultrasound confirms that the target lesion stenosis is ≥50%, accompanied by at least one of the following clinical manifestations: elevated venous pressure during dialysis, abnormal fistula signs, significant reduction in blood flow (\<200ml/min).

Guidewire and balloon successfully pass through the lesion and complete dilation. 6.Subjects or their legal representatives must understand the purpose of the trial, voluntarily participate in the clinical trial, and sign an informed consent form, while also being willing to adhere to the specific follow-up schedules set by this trial.

Exclusion Criteria

Target lesion located in the arterial segment or anastomosis of the AVF. Target lesion located in the lower limb AVF. Subjects with previous stent implantation in the AVF. Patients diagnosed with symptomatic central venous occlusive disease: AVF flow reduction accompanied by swelling of the ipsilateral limb, chest, or facial area, with DSA confirmation of central venous occlusive disease.

Subjects with two or more target lesions in the AVF (when two stenoses are less than 3 cm apart, they are considered as one target lesion).

Subjects with acute thrombosis in the AVF or who have undergone AVF thrombolysis or thrombectomy within the past 30 days.

Subjects who have undergone or plan to undergo surgical intervention on the AVF within 30 days.

Subjects with AVF infection or concurrent systemic active infection. Subjects planning renal transplantation or switching to peritoneal dialysis within the next 12 months.

Subjects with diseases causing coagulopathy, such as thrombocytopenic purpura. Subjects undergoing immunotherapy or suspected/diagnosed with vasculitis. Subjects with allergies or contraindications to heparin or contrast agents. Subjects who are pregnant or breastfeeding. Subjects with a life expectancy of less than 12 months.
