LilleAges 18 years+ - NCT04471740Recruiting
Study of hydrocephalus and sleep apnea
This study looks at people who may have normal-pressure hydrocephalus (fluid-related swelling in the brain) and also focuses on sleep apnea. It may help researchers understand whether treating or studying sleep issues could improve symptoms related to this condition.
Valencia, ValenciaAges 18 years+ - NCT04505618Recruiting
Eye scan study using special imaging for blood-vessel disease
This study uses a detailed eye scan (optical coherence tomography angiography) to look at how blood vessels in the retina are affected. It may help researchers better understand retinal vascular diseases, though some people will be excluded for safety or image-quality reasons.
Baltimore, MarylandAges 18–99 - NCT04584632Recruiting
Stent-like device for blocked leg arteries in the thigh or knee
This trial studies a new stent-like vascular scaffold to improve blood flow in people with symptomatic blockage in the thigh/knee artery. It may help reduce symptoms from narrowed or blocked arteries, but you must meet several artery and health requirements.
Sydney, New South WalesAges Any age - NCT04701749Recruiting
Stopping blood thinners with a left-atrial device in bleeding risk
This trial studies whether it’s safe to temporarily stop blood-thinning medicine in people with long-term atrial fibrillation who have bleeding from a radiation-damaged bladder. It uses a procedure with a device placed in the left atrium to help lower stroke risk while reducing bleeding risk.
Clermont-FerrandAges 18 years+ - NCT04760977Recruiting
HEMS care for bleeding trauma with low blood pressure
This trial studies how emergency helicopter (HEMS) teams manage trauma patients who have signs of shock from blood loss, especially when bleeding is suspected or ongoing. It may help teams choose the best pre-hospital approach to stabilize you sooner.
AlessandriaAges 18 years+ - NCT04831346Recruiting
Laser treatment to improve jaw opening in young women
This study tests whether low-level laser therapy can improve how far you can open your jaw and changes in jaw muscle activity in people with one-sided jaw muscle temporomandibular disorder (TMD). It may help reduce jaw movement limits related to that condition.
GizaAges 18–30 - NCT04861506Recruiting
Clot-removal treatment for blocked blood flow in the leg
This trial tests how safe and effective a clot-removal procedure done through the blood vessels is for people with acute or subacute blocked blood flow in the lower leg. It may help by improving circulation while carefully tracking risks and results.
Hangzhou, ZhejiangAges 18 years+ - NCT07523620Recruiting
Heart rhythm procedure with left atrial appendage closure
This trial tests a procedure that closes off a small pouch in the heart (left atrial appendage) while also treating irregular heartbeat (atrial fibrillation) with a catheter ablation procedure. The goal is to reduce your stroke risk and treat your symptoms without needing blood thinners long-term.
Brussels, B CAP RAges 18 years+ - NCT05100693Recruiting
FETO balloon removal during pregnancy for diaphragm hernia
This trial studies “smart removal” of a balloon placed in the womb to treat a baby’s congenital diaphragmatic hernia (CDH). It aims to see if removing the balloon in a planned, safer way can improve outcomes for the baby and keep mothers safe.
LeuvenAges 18 years+ - NCT05199662RecruitingPhase 3
IV clot-busting medicine for stroke when standard options don’t fit
This trial tests whether giving IV TNK (tenecteplase) plus standard stroke care can improve outcomes in some people who have a new stroke but cannot get alteplase (another clot-busting drug) and do not have a large blocked artery that can be treated with a procedure. It’s meant for strokes with “mismatch” findings on scans that suggest salvageable brain tissue.
