Endobronchial Valves + Blood Patch for Pneumothorax
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new method for treating persistent air leaks (PALs), which are stubborn lung air leaks that can slow recovery and extend hospital stays. Researchers aim to determine if endobronchial valves (tiny devices placed in the airways) combined with a blood patch (using the patient's blood to seal the leak) can expedite the repair of these leaks. Participants will undergo a bronchoscopy (a procedure to examine the lungs) to evaluate this combined treatment. This trial targets adults with PALs who cannot or choose not to undergo surgery. As an unphased trial, it offers patients the chance to explore innovative treatment options that might not be available elsewhere.
Do I have to stop taking my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that this technique is safe for treating persistent air leaks?
Research has shown that using endobronchial valves and blood patches is generally safe for treating ongoing air leaks in the lungs. In one study, about 61% of patients experienced cessation of air leaks within 30 days after receiving valve treatment, with no procedure-related deaths reported.
Another study found that the treatment successfully stopped air leaks in 36% of patients, with only a few experiencing a recurrence. While it might not work for everyone, most patients tolerate the treatment well.
Overall, these findings suggest that the treatment is safe, with most patients achieving good results and experiencing no serious side effects.12345Why are researchers excited about this trial?
Unlike the standard treatments for persistent air leaks, which often involve surgical interventions or prolonged chest tube management, this innovative approach uses a combination of endobronchial valve placement and endobronchial blood patching. Researchers are excited about this treatment because it offers a minimally invasive, nonsurgical option that directly targets and manages air leaks. This method could significantly reduce recovery times and complications associated with more invasive procedures, providing a new hope for patients who aren't suitable candidates for surgery or those who prefer to avoid it.
What evidence suggests that this technique is effective for persistent air leaks?
Research has shown that endobronchial valves (EBVs) can help treat persistent air leaks (PALs). In one study, about 60.6% of patients had their air leaks resolved within 30 days after receiving EBV treatment. Another study found that EBVs significantly reduced air leaks in 9% of patients. In this trial, participants will receive a combination of EBVs and a blood patch, which may improve these results, offering a promising option for those with PALs. Although complications can occur, no deaths related to the procedure have been reported. Overall, this method provides a less invasive way to manage air leaks, potentially leading to quicker recovery and shorter hospital stays.13467

Are You a Good Fit for This Trial?
This trial is for adults with persistent air leaks, a condition that can extend hospital stays and delay recovery. Participants must be undergoing bronchoscopy to locate the source of the air leak. Specific inclusion or exclusion criteria are not provided.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Treatment

What Are the Treatments Tested in This Trial?
Interventions
- Endobronchial Valve Placement and Endobronchial Blood Patching
Trial Overview
The PATCHVALVE study tests if combining endobronchial valve placement with blood patching speeds up the healing of persistent air leaks in patients' lungs. It involves standard bronchoscopy, instilling patient's own blood mixed with TXA into their lung, then placing a valve to seal off leaks.

Treatment groups
Experimental Treatment
This study will enroll patients with persistent air leaks (PAL) following lung resection or unrelated to lung resection, who have ipsilateral chest tubes in place and are either not suitable candidates for surgical intervention or have declined surgery. Participants will undergo a combined bronchoscopic approach involving endobronchial valve (EBV) placement and endobronchial blood-patch application, aiming to effectively manage air leaks through a minimally invasive, nonsurgical technique.
