Iliac vein stenting for chronic post-thrombotic venous ulcers
This trial tests whether placing a stent (a small mesh tube) in the iliac vein can help heal chronic leg ulcers caused by prior blood clots. The goal is to improve blood flow and reduce symptoms.
CairoAges 18–70 - NCT06753786Recruiting
Blood thinner timing study for bleeding stroke patients
This study looks at when it is safest to start blood thinners to prevent blood clots (deep vein thrombosis) after a type of bleeding stroke called hypertensive intracerebral hemorrhage. Researchers want to find the best time to start this prevention treatment.
MoscowAges 18 years+ - NCT06729021Recruiting
Predicting leg blood clots after heart or lung surgery
This study tests whether a simple score (Modified Caprini) and a blood test (D-dimer) can help predict and prevent blood clots in the legs after heart or lung surgery. If you are having cardiothoracic surgery and will be in the hospital for a few days, you may be able to join.
BaghdadAges 18 years+ - NCT06886516RecruitingEarly Phase 1
Blood thinner study for cancer patients with low platelets
This study tests if the blood thinner apixaban is safe and effective for cancer patients who have low platelets and a recent blood clot. It may offer a treatment option for those who cannot take standard blood thinners.
Boston, MassachusettsAges 18 years+ - NCT05588284Enrolling by invitation
Check whether a special treatment protects vein valves after clot
This study enrolls people with an acute blood clot in the thigh or pelvis veins to see how well a procedure called PCDT (using a Zelante device) preserves the function of vein valves. It may help reduce complications like ongoing vein problems after a clot.
Chuzhou, AnhuiAges 18–80 - NCT07372170Recruiting
Blood thinners for preventing another clot in low-risk APS
This study looks at how well blood thinners prevent blood clots from coming back in people with antiphospholipid syndrome (APS) who are considered low risk. It compares two types of medicines: direct oral anticoagulants (DOACs) and vitamin K antagonists.
Madrid, MadridAges 18 years+ - NCT06909240Recruiting
Walking training after first leg blood clot: a study
This study tests whether a progressive walking program helps people recover better after their first leg blood clot (DVT). You would be part of a walking training group and researchers will see if it improves walking ability and leg symptoms.
Hvidovre, Capital RegionAges 18 years+ - NCT05041569Recruiting
MRI study of brain vein damage and swelling patterns
This pilot study uses an MRI scan that involves an injected contrast to look at how brain blood-flow pathways are being blocked or narrowed. The goal is to better understand the kind of damage caused by these vein problems, which may help doctors monitor and plan care.
Paris, ParisAges 18 years+ - NCT07140211RecruitingPhase 3
Low-dose heparin to prevent blood clots after childbirth
This trial is testing a short course of a low-dose blood thinner (heparin) to prevent dangerous blood clots in the legs or lungs after childbirth. It is for women who have certain risk factors that make clots more likely.
BadenAges 18 years+ - NCT04924322RecruitingPhase 2/Phase 3
Early blood clot prevention after certain central line insertions
This trial tests whether starting enoxaparin (a blood-thinner) within 24 hours after placing a specific type of central line can prevent dangerous clots. It may help reduce clot risk in people whose line is placed in the neck or thigh vein, while also tracking bleeding side effects.
Birmingham, AlabamaAges Up to 17 years - NCT05789108Recruiting
Study of first leg blood clot and long-term effects
This study looks at people having their first blood clot in the leg and how it can affect them long-term. It may help doctors better predict complications and improve follow-up care after an emergency visit.
Hvidovre, CopenhagenAges 18 years+ - NCT05881798Recruiting
Vena cava filter data study for specific filter type
This study checks outcomes and safety using real-world health data from people who received a specific type of vena cava filter. It may help improve future care by understanding how these devices perform after placement.
Los Angeles, CaliforniaAges 18 years+ - NCT06731673Recruiting
HSP47 protein study in blood clots
This study looks at a protein called HSP47 in people with blood clots, heart attacks, or strokes caused by atrial fibrillation, compared to healthy volunteers. It aims to learn more about how blood clots form and may lead to better treatments.
Aarhus, Central RegionAges 18 years+ - NCT06780462RecruitingPhase 3
Steroids with or without blood thinners for Behçet's vein clots
This trial tests whether adding a blood thinner (anticoagulant) to steroid therapy is more effective than steroids alone for treating deep vein thrombosis (a blood clot in a large vein) in people with Behçet's syndrome. It aims to find the best way to prevent future clots and reduce side effects.
BordeauxAges 18 years+ - NCT06998745Recruiting
Anticoagulant therapy support for colorectal cancer patients with blood clots
This trial tests whether a medication therapy management (MTM) model helps make blood thinner treatment safer and more effective for colorectal cancer patients who have also developed dangerous blood clots. It aims to improve how well patients stick to their medication and reduce complications.

Blood Clots in Veins of the Gut During Pancreatitis
This study looks at how often blood clots form in veins near the gut (called splanchnic venous thrombosis) in people with acute pancreatitis. It also checks if the clots are linked to how severe the pancreatitis is. The goal is to help doctors better understand and possibly prevent these clots.

Donate blood for a heart and metabolism research biobank
This study builds a “biobank,” which is a collection of blood and related samples, to support future research on heart and metabolic (sugar/body-fat) conditions. It may help researchers better understand these diseases and improve future prevention and treatments.
