Randomized Study Comparing Pulmonary Embolism Rates After Endovascular Treatment of Thrombosed Dialysis Fistulas Using Balloon Thrombectomy or Thromboaspiration

What this Trial Is About

This research aims to compare the occurrence of pulmonary thromboembolism PTE in patients with acute thrombosis of native or prosthetic arteriovenous fistulas AVF undergoing endovascular treatment. The study evaluates two treatments balloon thrombectomy and thromboaspiration systems. It also examines the primary patency rate, clinical success rate, and costs associated with each thrombectomy technique. Participants will receive either balloon thrombectomy, where a catheter with an inflatable balloon removes the clot by pressure, or a thromboaspiration system, which uses suction to gently remove the clot. Both procedures are guided by imaging techniques to ensure accurate placement. The study is randomized and double-blind, with patients assigned to one of these two treatment groups. During the study, the presence of PTE will be assessed within 24 hours after treatment using AngioCT, and the resolution of PTE will be evaluated one month later. Researchers will monitor clinical success, patency rates of the fistulas, and treatment costs. Participants will be followed closely to measure these outcomes and safety over the study period.
