What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study watches what happens to the lungs when doctors use a balloon to clear a clot in a dialysis patient's arm graft. Using a special belt that takes pictures of lung activity, researchers will check if tiny clot pieces briefly affect how air and blood flow in the lungs. Twenty adults with kidney failure on dialysis will be monitored before, during, and after the procedure.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could help doctors understand how small blood clots from angioplasty affect lung function, potentially improving safety during the procedure.
What could go wrong
This is a very small pilot study with only 20 participants, so results may not apply to everyone. It only observes changes and does not test a new treatment.

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Patients with end-stage renal disease (ESRD) undergoing maintenance hemodialysis who present with thrombosed arteriovenous grafts (AVG) requiring clinically indicated percutaneous transluminal angioplasty (PTA) to restore patency. The study population will consist of adult patients (18-80 years) admitted to the interventional radiology or dialysis access unit of the First Affiliated Hospital of Wannan Medical College (Yijishan Hospital). All participants will receive routine PTA treatment as part of standard care. EIT monitoring will be applied non-invasively to collect ventilation and perfusion signals before and after PTA. No additional interventions beyond routine clinical management will be introduced.

Ages

18 years and older

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Inclusion Criteria 1. Age ≥ 18 years. 2. Diagnosis of end-stage renal disease receiving maintenance hemodialysis. 3. Documented AVG thrombosis requiring PTA. 4. Able to cooperate and tolerate EIT monitoring. 5. Provided written informed consent. Exclusion Criteria 1. Severe respiratory failure incompatible with supine position. 2. Thoracic skin condition or deformity preventing EIT electrode placement. 3. Acute pulmonary embolism or acute pulmonary edema before procedure. 4. NYHA Class IV heart failure or hemodynamic instability. 5. Pregnancy or breastfeeding. 6. Any other circumstance judged unsuitable by investigator.
