Orthopedic DVT/PE Prophylaxis Practices

Despite the existence of evidence-based guidelines, DVT/PE prophylaxis practices reported by THA/TKA surgeons participating in NBCA’s survey vary widely: 70% pneumatic compression, 69% ambulation, 58% compression stockings, 47% LMWH, 28% warfarin, 15% LMWH with transition to warfarin, and 14% aspirin.

The survey findings validate the need for interventions to address anticoagulant treatment barriers, and the need to better define optimal DVT/PE prophylaxis for THA and TKA patients to overcome longstanding therapeutic obstacles. This can be accomplished with comparative effectiveness research, combined with consensus building efforts — such as a CDC/NIH Consensus Development Conference, for example — to optimize prophylaxis among at-risk THA/TKA patients.

🌍 Today is World Diabetes Day.

Did you know that people with diabetes have a higher risk for blood clots? Both Type 1 and Type 2 diabetes can create conditions that make clots more likely, but awareness and prevention can make a lifesaving difference.

👉 How diabetes increases clot risk:

• High blood sugar can damage blood vessels and increase inflammation.

• Obesity and low activity levels raise the risk further.

• Related conditions like heart disease, stroke, and high blood pressure also contribute.

• Circulatory issues, such as peripheral artery disease, make clots more likely, especially in the legs.

👉 What you can do:

✅ Stay active and manage your blood sugar.

✅ Know the warning signs — leg pain or swelling, redness, chest pain, or sudden shortness of breath.

✅ Talk to your healthcare provider about your personal risk.

🩸 Take a moment to assess your risk: Link in bio.

Let’s raise awareness this #WorldDiabetesDay — share this post to help others understand the connection between diabetes and blood clots.

🎉 Exciting new research offers hope for safer blood clot prevention after knee replacement surgery.

A team of researchers led by NBCA Medical and Scientific Advisory Board member Dr. Jeffrey Weitz of @McMasterU tested two new medicines that block a clotting protein called factor XI. They found that one of them prevented blood clots better than today’s standard treatments after knee surgery, without increasing bleeding complications.

Dr. Weitz presented these findings last week at the @american_heart's Scientific Sessions 2025 in New Orleans.

This research could pave the way for a new type of blood thinner that prevents dangerous clots while reducing bleeding risks for patients after surgery.

“It was a couple of days after traveling when I

“It was a couple of days after traveling when I first noticed something wasn’t right. I had switched birth control pills within the last several months. I was at a conference, mid-presentation, when I realized that I couldn’t quite get through full sentences without pausing for breath. I told myself it was just nerves. Even at the gym that week, I felt more fatigued than usual — nothing alarming, just off.

When I got home, I noticed it again walking up stairs, and then during a mountain-bike ride, it became undeniable. I was short of breath riding from the parking lot to the trailhead, and my heart rate had jumped to 130 — much higher than normal for that effort. I sat down, felt a dull ache in my calf that I’d ignored earlier in the week, and suddenly it all clicked. I likely had a DVT and pulmonary embolism.

Even then, I hesitated to go to the hospital — it didn’t feel that bad, and I worried I’d be embarrassed if it was nothing. It wasn’t nothing. I was admitted and underwent a thrombectomy for a significant pulmonary embolism.

Looking back, I realize how easily this could have been missed — especially in athletes. My resting heart rate was only in the 90s, higher than normal for me but not technically tachycardic, and I never had chest pain. That’s what makes it so unsettling: the symptoms can be incredibly mild.

In a recent Stop the Clot video, @TatyanaMcFaddenUSA talked about how hard it was to return to activity — and I really relate to that. I underestimated how difficult it would be to get back to endurance exercise. I’m used to being in shape, and even though I didn’t take much time off, it took me nearly a year to get back to where I was before it happened. Even now, I still have to fight the panic that comes with shortness of breath — especially during mountain-bike races. I know it’s probably not another PE, but that fear still lives in my body.

It’s normal to feel anxious and uncertain after a clot. I got better with time—and therapy helped most.”

Today is Genetic Counselor Appreciation Day!

Genetic counselors play an important role in helping patients and families understand inherited clotting risks, known as thrombophilia.

They provide compassionate guidance, helping patients:

💬 Understand the role of genetics in blood clots
🧭 Decide whether testing is the right choice
📄 Interpret complex test results
💞 Communicate important information with family members

We’re very thankful for the genetic counselors who empower patients with knowledge, support, and clarity, and who help make personalized care possible for those at risk of blood clots.

New research shows how quickly blood clot treatmen

New research shows how quickly blood clot treatment is evolving.

A national study found that thrombectomies, or procedures to remove pulmonary emboli from the lungs, have increased more than 700% since 2017.

Experts say this sharp rise reflects major improvements in technology that now make these minimally invasive treatments safer and more effective than they were a decade ago.

Most of these procedures are now done in outpatient hospital settings, reflecting how treatment for blood clots is becoming less invasive and more accessible.

🌟 November 12 is CTEPH Awareness Day. Chronic t

🌟 November 12 is CTEPH Awareness Day. Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare but serious complication that can occur after a pulmonary embolism (PE).

It happens when blood clots don’t fully dissolve, leaving behind scar-like tissue that blocks or narrows the arteries in the lungs. Over time, this can cause high blood pressure in the lungs and strain on the heart.

Common symptoms include fatigue and unexplained shortness of breath. Some people may also experience a dry cough, chest pain, or rapid heartbeat. About 1 in 25 people who have a PE could develop CTEPH.

👉 Last year, the National Blood Clot Alliance hosted a PEP Talk with Dr. Timothy Fernandes, pulmonologist at UC San Diego Health, to discuss CTEPH and other post-clot complications.

Dr. Fernandes emphasized that CTEPH is often underdiagnosed and that listening to patients’ symptoms is key to early detection. He also urges patients to push for answers.

🎖️ This Veteran’s Day, we honor those who have served — and continue to serve — our country with courage and sacrifice.
As we salute our heroes, we’re also raising awareness about an important health issue affecting many in the military and veteran community: blood clots.

Military personnel and veterans face a higher risk for developing blood clots due to factors like:

1️⃣ Injuries and surgeries: Combat-related trauma, surgical recovery, and long periods of immobility can damage blood vessels and increase clotting risk.

2️⃣ Prolonged immobility and travel: Extended flights, deployments, or recovery periods with limited movement can all contribute to clot formation.

3️⃣ High stress levels: Physical strain and emotional stress, including post-traumatic stress disorder (PTSD), may cause inflammation that elevates clotting risk.

4️⃣ Underlying health conditions: Veterans have higher rates of hypertension, diabetes, or other cardiovascular conditions that can further increase risk.

🩸 Recognizing the signs — leg pain or swelling, chest pain, or shortness of breath — can lead to faster diagnosis and lifesaving treatment.

Today and every day, we honor our veterans by protecting their health and spreading awareness that saves lives.

🏒 Today we’re thinking of @Penguins forward @FilipHallander, who was recently diagnosed with a blood clot in his leg and is expected to be sidelined for at least three months.

Although pro athletes are often young and healthy, the physical demands of sports can raise clot risk:

• Dehydration from intense training

• Injuries or surgeries that limit movement

• Long travel to games or events

• Repetitive motions that compress veins (like pitching or cycling)

Knowing the signs, including sudden arm or leg pain and swelling or unexplained shortness of breath, can save lives.

The National Blood Clot Alliance wishes Filip a full and speedy recovery.

👉 “In February 2025, while at work, I started

👉 “In February 2025, while at work, I started developing a terrible headache, fever, chills, and body aches. I assumed I was coming down with the flu. I spent a day in bed watching TV and resting. Two days later, the flu-like symptoms subsided, but I developed stiffness and pain in my neck. Within 24 hours, that pain moved from my neck to my arms, and then to my legs. Something felt off, so I went to the ER.

My platelets were high, but the doctors sent me home with a diagnosis of “post-viral inflammation.” I left feeling anxious and uneasy, with a strong sense that something was seriously wrong. The next morning, I went back to the ER—again, I was sent home, and my platelets were even higher. On day three, I returned. Sent home. Day four, the same thing. Each time, my anxiety grew stronger. I just couldn’t shake the feeling that something was being missed.

While waiting hours in the ER (15 to 18 hours each visit), I started researching my symptoms and examining my lab results—I have a small medical background—and kept asking if they were checking for blood clots. I was told I wasn’t at risk and to stop Googling. No one, not even my parents or my husband, took me seriously.

On day five, I went back to the ER again. After waiting 18 hours, a doctor came in, and I told him I wasn’t leaving until they ran a D-dimer test. He finally agreed. Within an hour, he returned and told me it was positive. I was immediately taken for a CT scan, which revealed a bilateral pulmonary embolism (PE).

That week, I saved my own life.

I still don’t have answers. I’m on blood thinners and following up with a hematologist, but no one can tell me why it happened. I continue to advocate for myself and keep searching for answers.

I struggle with health trauma and daily anxiety. Every ache and pain sends me into a spiral of fear. I’m terrified to stop blood thinners or even catch a cold, because I don’t know what caused this to happen.

Listen to your gut no matter what friends, family or professionals say. If you don’t feel right in your body, advocate for yourself!”

🩸 Your story could save a life.

Telling your blood clot story is an act of courage, empathy, and healing. Many survivors find that sharing their experience helps them process what they’ve been through while also helping others recognize the signs, seek help sooner, and find hope and understanding as they begin their own recovery.

Because blood clot symptoms often mimic other conditions, diagnosis is sometimes delayed. Your story could be the reason someone recognizes the signs sooner and gets the help they need.

Whether you were misdiagnosed at first, faced a long recovery, or are still navigating life after a clot, your story matters. 💬

❤️🩸 “I’m 30 years old and have a complicated medical history. As a teenager, I was diagnosed with fibromyalgia and Ehlers-Danlos syndrome, and today I manage more than 20 different health conditions.

On April 20, 2021, I felt severe pain in my left leg. It was swollen, purple, and hot to the touch. I called my doctor, who told me to go to the ER right away because it could be a blood clot.

I remember thinking, ‘I’m only 25 — how could I have a blood clot?’ But tests confirmed it: I had a deep vein thrombosis (DVT) in my left leg, and scans showed blood clots in both lungs (pulmonary embolisms). I was shocked and scared.

Because the ER wasn’t connected to a hospital, I was transferred by ambulance and started on a blood thinner through an IV. I spent a day there and was sent home on medication called rivaroxaban. Later testing showed I have a genetic condition called factor V Leiden, which makes blood clots more likely. Some of my relatives had it too and sadly died from clots.

Six months later, I developed more clots in both legs. I spent six days in the hospital and learned that the first medication hadn’t worked for me. My doctors switched me to warfarin, another blood thinner that requires regular testing to make sure it’s working safely.

Because I couldn’t easily leave home, my mom helped me advocate to get blood tests done at home. Insurance approved it, and now I use a small device to test my blood by pricking my finger—just like someone checking their blood sugar.

No matter how young or healthy you think you are, blood clots can happen to anyone—especially if you have a condition like factor V Leiden. I never thought it could happen to me, but it did. And I hope my story reminds others to listen to their bodies and speak up if something doesn’t feel right.”

In response to our recent post, so many of you sha

In response to our recent post, so many of you shared your experiences with blood clotting disorder testing — also called thrombophilia testing — and no two stories were the same.

➡️ One person learned she had a prothrombin gene mutation after five miscarriages and was later diagnosed with antiphospholipid syndrome.

➡️ Another experienced a clot during military training that was initially dismissed as a muscle strain. Testing later showed she is positive for factor V Leiden.

➡️ Some learned about their inherited risk after multiple pulmonary emboli and now worry about whether their children could have inherited the same condition.

➡️ Others have faced repeated clots without a clear answer despite extensive testing.

These stories show just how complex thrombophilia testing can be and why communication, timing, and access to care are so important.

Join us for our next PEP Talk, Thrombophilia Testing While on Blood Thinners, on Tuesday, November 11 at 7 p.m. ET to learn more about who should get tested, when, and why. Plus, your rights and options if you’re interested in testing that isn’t routinely recommended.
