Clermont-FerrandAges 18 years+ - NCT05281055Recruiting
Registry of clot-removal treatment for sudden large-vessel strokes
This study keeps a record of people treated with a clot-removal procedure (endovascular thrombectomy) for a sudden stroke caused by a blocked large blood vessel in the brain. It focuses on outcomes for patients who can be treated within 24 hours and were independent before the stroke.
TaipeiAges 20 years+ - NCT05286710Recruiting
Thrombectomy treatment for new blood clots in the leg
This trial studies a procedure to remove an acute deep vein blood clot in the leg. It may help restore blood flow faster than standard treatment for certain clot locations.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT05320263Recruiting
Thrombectomy timing: aspiration tube vs stent for basilar stroke
This trial compares two ways to remove a blockage in the brain’s basilar artery: suction (aspiration) versus a retriever stent. It may help doctors learn which approach works better for restoring blood flow in acute stroke patients.
BordeauxAges 18 years+ - NCT05326932Recruiting
Extended-Time Thrombectomy for Large-Artery Stroke
This trial studies whether a mechanical procedure to remove a blocked artery can help people with an ischemic stroke caused by a large artery blockage, even when treatment starts 24–72 hours after symptoms began. It also checks that only patients with “salvageable” brain tissue on CT scans are treated.
ShanghaiAges 18 years+ - NCT05554588Recruiting
Thrombus-finding treatments for heart attack during angioplasty
This trial compares two ways to remove or break up a blood clot during emergency heart artery opening (primary PCI) for a specific type of heart attack (STEMI). It may help patients with a high clot burden by testing whether one approach works better than the other to improve outcomes.
Beijing, Beijing MunicipalityAges 18–80 - NCT05561088Recruiting
Head acupuncture after stroke clot removal
This trial studies whether doing head acupuncture after a procedure to remove a stroke-causing blood clot can improve recovery and safety. You may be considered if you had endovascular clot removal within 24 hours and meet specific brain-scan and stroke-severity measures.
Xi'an, ShaanxiAges 18–100 - NCT05868161Recruiting
Registry for patients treated with a thrombectomy device
This registry collects past treatment information from people who had a clot procedure using the Pounce Thrombectomy System. It helps researchers understand how this device is used in real-world care and what outcomes may look like.
Peoria, IllinoisAges 18 years+ - NCT05892510RecruitingPhase 2/Phase 3
Tenecteplase after clot removal for no-reflow stroke
This trial tests whether giving tenecteplase directly into the brain artery after a thrombectomy can improve outcomes when blood flow doesn’t fully return (“no-reflow”) in an emergency stroke. It may help some people by reducing ongoing clot-related blockage after the main clot is removed.
Gold Coast, QueenslandAges 18 years+ - NCT05983757Recruiting
Clot retrieval for smaller brain artery strokes
This trial tests if removing clots from smaller arteries in the brain (not the main ones) helps people who had a stroke and can't get standard clot-busting medicine. It compares clot removal to usual care for strokes caused by these medium-sized vessel blockages.
Atlanta, GeorgiaAges 18 years+ - NCT06051032Recruiting
Comparing balloon vs. suction for clotted dialysis fistulas
This study compares two ways to clear a sudden clot in a dialysis fistula (AVF). It uses either a balloon (to push the clot out) or a suction device (to pull the clot out) to restore blood flow.
Valencia, ValenciaAges 18 years+ - NCT06200753Recruiting
Late stroke treatment study for large vessel blockages
This study looks at patients who had an ischemic stroke (a type of stroke caused by a blood clot) more than 24 hours ago and have a blockage in a large brain artery. It compares outcomes for those who get a procedure to remove the clot versus those who get only medical treatment.
Tianjin, Tianjin MunicipalityAges Any age - NCT06210633Recruiting
Clot removal trial for very large strokes
This trial tests a procedure called endovascular thrombectomy (clot removal through a catheter) for people with very large strokes. It aims to see if removing the clot can help even when a large part of the brain is already damaged.
Xiangtan, HunanAges 18 years+ - NCT06288906Recruiting
Mechanical Clot Removal for Deep Vein Thrombosis
This trial tests a mechanical device that removes blood clots from deep veins in the pelvis or leg. It may be an option if you have a large clot and are at low risk for bleeding.
Milan, ItalyAges 18 years+ - NCT06289985Recruiting
Expanding clot removal for medium vessel strokes
This trial tests a new approach to see if removing clots from medium-sized brain blood vessels can help more patients recover from stroke. It aims to expand the use of a standard clot-removal procedure to people with less severe symptoms or blockages in smaller vessels.
Birmingham, AlabamaAges 18 years+ - NCT07687576RecruitingPhase 2/Phase 3
Comparing clot removal methods for heart attack patients
This trial tests if a special device that sucks out blood clots during a heart attack is better than standard care for reducing clot size before placing a stent. It may help patients who have a large clot and a blocked artery.
Oxford, OxfordshireAges 18 years+ - NCT06559241RecruitingPhase 3
Arm or leg cuff treatment for large clot stroke recovery
This trial tests whether a simple, non-invasive treatment (repeated inflation of a blood pressure cuff on your arm or leg) can help people recover better after a stroke caused by a large clot. You must be having a mechanical thrombectomy (clot removal) within 24 hours of your stroke.
Suzhou, AnhuiAges 18 years+ - NCT06559475Recruiting
Testing a new aspiration catheter for large vessel stroke
This trial tests a new catheter (Super-Bore 8/7F) to remove blood clots in people having a major stroke caused by a blocked large artery in the brain. The goal is to see if it is safe and effective at restoring blood flow when used within 24 hours of stroke symptoms starting.
Hefei, AnhuiAges 18 years+ - NCT06663631RecruitingPhase 1
Hibernation-like therapy for stroke recovery after clot removal
This trial tests if a hibernation-like therapy can improve recovery after a stroke caused by a large blood clot in the brain. It is for people who are having a stroke and are scheduled for a procedure to remove the clot.
Linyi, ShandongAges 18–80 - NCT07115940Recruiting
Clot removal after 24 hours for stroke patients
This trial tests if removing a large blood clot from the brain up to 3 days after a stroke improves recovery compared to standard medical care alone. It is for patients who have a severe stroke and are otherwise healthy enough for the procedure.
Chicago, IllinoisAges 18–85 - NCT06741332Recruiting
AI software to speed up stroke clot removal referrals
This trial tests whether a special AI software can help doctors speed up the process of referring patients with acute stroke for a procedure that removes a blood clot (thrombectomy). If you have stroke symptoms and a recent CT scan, the AI may help identify if you could benefit from this treatment.
Granollers, BarcelonaAges 18 years+ - NCT06752096Recruiting
Robot-Helped Brain Blood Vessel Procedures
This trial uses a robot to assist with brain blood vessel treatments, like checking for blockages, treating tumors, or removing clots. It may help make these procedures more precise and safer.
Seoul, KoreaAges 18–80 - NCT06825897Recruiting
Direct to angiography suite for stroke clot removal
This trial compares two ways to treat severe stroke patients with a large vessel blockage. One way is the standard approach of first imaging you and then deciding. The other way takes you directly to the angiography suite for immediate clot removal by the doctor. The goal is to see if this faster, direct approach helps you get better results.
