Outcomes of rectal artery embolization for bleeding hemorrhoids
This study looks at how well rectal artery embolization (a procedure that uses tiny particles to block blood flow to hemorrhoids) works for treating bleeding internal hemorrhoids. It aims to understand if this treatment improves quality of life and reduces symptoms.
Rochester, MinnesotaAges 18–90 - NCT06077747Recruiting
Lumbar vein treatment for chronic headaches with nutcracker anatomy
This study tests a procedure called lumbar vein embolization to treat daily headaches that feel like pressure and get worse when lying down. It's for people who have a rare anatomy where a vein in the kidney is pinched (nutcracker physiology), and standard headache medicines haven't helped.
Jacksonville, FloridaAges 18 years+ - NCT06041594Recruiting
Treating pulmonary embolism with the Laguna thrombectomy system
This trial tests a device (Laguna Thrombectomy System) to remove blood clots in the lungs. It may help people with a recent pulmonary embolism who are stable enough to undergo a minimally invasive procedure.
Birmingham, AlabamaAges 18–85 - NCT05791786Recruiting
Registry for suspected amniotic fluid embolism patients
This study builds a long-term registry and sample library for people diagnosed with suspected amniotic fluid embolism (AFE), and for certain related hospital deaths. It helps researchers understand what AFE looks like, how it affects health over time, and how to improve future care.
Houston, TexasAges Any age - NCT05697562Recruiting
Embolization treatment for hemorrhoid bleeding
This trial studies a procedure that blocks blood flow to bleeding hemorrhoids (called superior rectal arterial embolization). It may help people with hemorrhoid bleeding who are being considered for treatment, especially when bleeding is significant.
JetteAges 18 years+ - NCT05591118RecruitingPhase 3
Catheter treatment to remove blood clots in the lungs
This Phase 3 trial tests a catheter-based procedure to remove a lung blood clot (pulmonary embolism) and reduce strain on the heart. It may help people who have specific CT scan signs of right-heart strain.
Birmingham, AlabamaAges 18 years+ - NCT05482269Recruiting
Using CT scans to predict outcomes after lung blood clots
This trial uses an artificial intelligence (AI) system to read CT scan images of the lungs and predict outcomes after a pulmonary embolism (a blood clot in the lung). It may help doctors identify who is at higher risk, so treatment decisions can be faster and more accurate.
Shenyang, LiaoningAges 18 years+ - NCT05416567Recruiting
Embolization for meningioma using blood-vessel blockage
This trial studies whether a procedure that blocks the tumor’s blood supply (embolization) can help people with a typical meningioma that is growing or causing symptoms. It may help shrink or control the tumor by cutting off its main blood supply.
TrondheimAges 18 years+ - NCT05374681Recruiting
Test a minimally invasive add-on treatment for brain vessel swelling
This trial studies whether an add-on, minimally invasive procedure works better than standard care for a specific brain blood-vessel problem (CSH) that is larger than 10 mm. It may help reduce symptoms or prevent worsening, if you meet the size and location requirements.
Amiens, FranceAges 18 years+ - NCT05273762Recruiting
Removing blood clots from the lungs with a catheter
This trial tests a device called the FlowTriever to remove blood clots from the lungs in people with a pulmonary embolism that is not too severe. The goal is to see if this treatment can help improve heart function and symptoms without major surgery.
Mount Kisco, New YorkAges 18 years+ - NCT05098769Recruiting
Prediction tool for risks after acute pulmonary embolism scans
This trial studies a tool that uses CT scan results and heart blood tests to predict the chance of serious outcomes after an acute pulmonary embolism (a blood clot in the lung). It may help doctors identify higher-risk patients sooner.
Shenyang, LiaoningAges 18 years+ - NCT05103670Recruiting
PET/CT lung scan to assess recovery after pulmonary embolism
This study uses a special scan (PET/CT) and an inhaled/linked tracer to measure how well air and blood flow work in different lung areas after a pulmonary embolism. It’s meant to better understand regional lung function and how rehabilitation may help some people recover.
BrestAges 18–99 - NCT05015153Recruiting
Rehab after blood clot in the lungs to improve daily life
This study looks at whether pulmonary rehabilitation (a supervised exercise and support program for lung recovery) improves quality of life after a lung blood clot. It focuses on people who have ongoing breathing-related limits after treatment with blood thinners.
Brest, FranceAges 18 years+ - NCT05050617Recruiting
Ultrasound in the ER to predict risks in pulmonary embolism
This trial checks whether a bedside ultrasound done in the emergency room can help predict which people with an acute pulmonary embolism are more likely to have bad outcomes. If you qualify, your care team will compare ultrasound findings with your later results to see if it can guide treatment decisions sooner.
York, PennsylvaniaAges 18 years+ - NCT04902248Recruiting
Compare two procedures for hard-to-stop upper stomach bleeding
This trial studies whether a newer “OTSC” procedure works as well as a standard procedure called angiographic embolization to stop active, hard-to-control upper gastrointestinal bleeding. It may help people whose bleeding continues or comes back even after initial endoscopy treatment.
Beijing, Beijing MunicipalityAges 18 years+ - NCT04923984Recruiting
Procedure to stop bleeding in a brain bleed using a small plug
This trial looks at a minimally invasive procedure that may stop bleeding in the space between the brain and its outer covering (a subdural hematoma). It’s being offered to people being evaluated in Canada, and the main goals are to see if the approach is safe and practical for routine use.
