If you've ever had a blood clot in a deep vein in your leg or arm, known as Deep Vein Thrombosis (DVT) , you may have some lingering problems. It's like a wound that heals, but it can leave a small scar or some discomfort. Today, we're going to talk about a condition that can have a long-term effect on some people after a DVT. This is what doctors call Post-Thrombotic Syndrome or Postphlebitic Syndrome .
What is Post-Thrombotic Syndrome? Simply put...
Imagine you have a deep vein thrombosis (DVT) in your leg or arm. Even if we treat it well, sometimes the clot can cause some damage to the vein. It's like something stuck in a water pipe and if you remove it, it still causes some damage to the pipe.
This damage can cause the veins to lose their flexibility and the valves that help blood flow do not work properly. This causes blood to pool in the damaged veins instead of returning to the heart. When blood pools in this way, the pressure inside the veins increases, causing symptoms such as pain and swelling . This is what we call the collection of symptoms (Post-Thrombotic Syndrome). Some people may have very mild symptoms, but others may be so severe that they cannot even function in their daily lives.
If you have had DVT within the past two years and are now experiencing these symptoms, see a doctor immediately. They can assess your condition and start appropriate treatment to bring you relief.
How common is this condition?
Post-Thrombotic Syndrome is actually a common condition among people who have had DVT. It affects between 20 and 50 out of every 100 people within two years of a DVT diagnosis. That means it affects a significant number of people.
If you have Post-Thrombotic Syndrome, it's very difficult for the blood in that damaged vein to return to the heart. This pooling of blood is what causes all sorts of problems.
What are the symptoms of this? How do we feel?
Post-Thrombotic Syndrome (PTS) symptoms primarily affect the leg or arm where the DVT occurred. You may experience things like:
- Pain: Pain in the leg, especially when walking or standing. This is sometimes called claudication .
- Pain or aching as if a vein is being rolled .
- Feeling of heaviness and fatigue in the arms/legs.
- Itching (Pruritus) .
- Numbness, tingling, and unusual sensations (Paresthesia) .
These symptoms may be mild for some people, but can be very severe for others. You may find that these symptoms worsen after standing or walking for a long time, and improve after a short rest. These discomforts may also increase towards the end of the day. For some people, these symptoms may be constant, or they may come and go.
What are the outward signs of Post-Thrombotic Syndrome?
Symptoms are things we feel. Signs are things we can see. Your doctor will also check for these signs.
- Swelling (Edema): Swelling of the affected arm or leg.
- Skin redness or discoloration.
- Thickening of the skin , a feeling like leather.
- The appearance of new varicose veins .
- The appearance of small spider veins .
- If the condition becomes severe, non-healing wounds (venous ulcers) may develop.
Why does this (Post-Thrombotic Syndrome) occur? What is the cause?
The simplest reason is damage to your veins due to Deep Vein Thrombosis (DVT) .
The deep veins in our legs and arms have one-way valves that allow blood to flow only in one direction. Like a door, it can only open in one direction. These valves help blood flow back toward the heart. However, when a blood clot forms inside a vein, the blood clot can damage those valves. Then the valves don't work properly.
As a result, blood travels very slowly. Instead of flowing efficiently towards the heart, blood pools in the veins. This increases the pressure inside the vein walls, causing the symptoms mentioned earlier.
Who is most at risk for this condition?
Anyone who has had a DVT can develop Post-Thrombotic Syndrome. However, the risk is higher if you have had repeated DVT , especially in the same arm or leg. That is, if you have had multiple blood clots in the same place.
Also, your risk is even higher if you have had any of these symptoms of a previous blood clot:
- If it had spread to a large part of the vein.
- A blood clot in the upper thigh or pelvis (called a proximal DVT ) is more dangerous than a blood clot in the calf (called a distal DVT ). The risk is especially high if the clot forms in the iliac vein or the common femoral vein .
- If you have a blood clot in a large vein in your upper body, shoulder, or upper chest (this is called axillo-subclavian vein thrombosis) .
- If there was a blood clot (residual thrombosis) that did not completely dissolve even after treatment.
In addition, there are several other risk factors:
- If you have a pre-existing condition such as chronic venous insufficiency (CVI) .
- If your Body Mass Index (BMI) is more than 30 (that means obesity).
How do doctors diagnose Post-Thrombotic Syndrome?
Doctors diagnose this condition mainly through a physical exam . During this exam, your doctor will:
- Ask about your medical history (such as how you have had DVT in the past, what treatments you have received).
- They ask about your symptoms and how they affect your daily life.
- Your legs and arms will be examined for signs of Post-Thrombotic Syndrome (such as swelling and skin changes).
Based on this information, the doctor will determine whether you have Post-Thrombotic Syndrome and, if so, how severe it is.
What is the Villalta scale?
You may have heard your doctor talk about the 'Villalta scale' . This is a standard way that doctors use to diagnose this condition and assess its severity. It's like a checklist with a score. It includes 5 symptoms and 6 points. The doctor gives a score for each symptom and sign:
- 0 points: It doesn't exist.
- Score 1: Slightly present.
- Score 2: Moderately present.
- Score 3: Very bad.
The doctor then adds up all these scores. If the total score is less than 4, you do not have Post-Thrombotic Syndrome. If you have 5 or more points, you have the condition.
The condition is further classified as mild, moderate, or severe based on these scores:
- Score 5 to 9: Mild condition.
- Scores 10 to 14: Moderate condition.
- If there are ulcers, or a score of 15 and above: severe condition.
Your doctor will explain these results to you and tell you what they mean.
Are there any special tests to diagnose this condition?
There is no specific diagnostic test to diagnose Post-Thrombotic Syndrome. However, in some cases, doctors may order a 'Duplex ultrasound' to see how blood is flowing through the veins.
What are the treatments for Post-Thrombotic Syndrome?
Treatment usually includes compression therapy, lifestyle changes, and exercise . Some people may need surgery or treatment for venous ulcers. Doctors will tailor treatment to each person's needs. The primary goal of treatment is to reduce your symptoms and improve your quality of life.
Compression therapy
Your doctor may tell you to wear special compression stockings . These are the most common type of compression therapy. These stockings should be worn regularly (usually daily). They put pressure on your leg muscles and improve blood flow in your veins. They may feel tight, but they should not be painful.
There are different types of socks that provide different levels of compression. Your doctor will prescribe the right type of socks for your needs.
It may take some time for you to get used to wearing these (compression stockings). It is important to talk to your doctor about how they feel and whether you can wear them properly. Your doctor may also adjust the level of compression depending on how you feel and how much relief the stockings provide for your symptoms.
Other treatments for thrush include:
- A venous-return assist device: For example , the Venowave® . This is a pump-like device that you wear around your neck to help improve blood flow. You can wear it at home or while you're out and about.
- Intermittent pneumatic compression (IPC) device: This is a pneumatic sleeve worn on the leg in a hospital setting.
Lifestyle changes
Making small lifestyle changes can go a long way in reducing your symptoms. Your doctor may recommend things like:
- Keep your legs above the level of your heart , whether you are sitting or lying down.
- Maintain a healthy body weight .
- Use moisturizers to prevent skin from drying out or cracking.
Exercise
Exercise can help improve blood circulation and reduce symptoms. For example, if Post-Thrombotic Syndrome has affected your legs, your doctor may recommend exercises that strengthen your leg muscles.
That's because your calf muscles are powerful pumps that act like a "second heart." When you walk, the contraction of your calf muscles helps pump blood from your legs and feet back to your heart. So, when you strengthen those muscles, your veins get the help they need to properly carry blood.
Exercise improves your flexibility and cardiovascular endurance. Always talk to your doctor before starting a new exercise program. He or she will tell you what exercises are safe and suitable for your needs.
Surgery
In some special cases, doctors may recommend surgery or endovenous treatment (for example, stenting) to improve blood flow in the veins. Your doctor will tell you whether such treatment is suitable for you.
Treatment for venous ulcers
If the condition becomes severe , venous ulcers can develop. It is very important to treat these ulcers properly and carefully. If not, serious complications, such as amputation, can occur. Your doctor may recommend one or more of the following:
- Antibiotics.
- Bandages or dressings to cover the wound.
- Compression bandages or stockings.
- Daily wound cleaning.
- Ointments.
- Pain relievers.
- Debridement is the removal of dead tissue.
- Referral to specialists to help manage chronic diseases like diabetes.
How long does Post-Thrombotic Syndrome last?
Post-thrombotic syndrome is a chronic condition . This means that your doctor can help you manage it, but it cannot be cured . Treatment can reduce your symptoms and improve your ability to function, socialize, and have fun as you would like.
Can Post-Thrombotic Syndrome be prevented?
Post-Thrombotic Syndrome cannot always be prevented. This is because Deep Vein Thrombosis (DVT) cannot always be prevented. However, you and your doctor can work together to reduce your risk:
- Identify and reduce risk factors for DVT: The best way to prevent DVT (Post-Thrombotic Syndrome) is to prevent it from developing in the first place. Try to reduce the risk factors that you can change. For example, you can reduce your risk by avoiding tobacco products, staying active, and maintaining a healthy weight. Your doctor will tell you which risk factors you should pay attention to and how to develop a plan for them.
- Early diagnosis and proper treatment of DVT: If you have a DVT, early diagnosis and treatment can help minimize the damage to your veins. It can also help prevent future DVTs. This is because if you have another DVT, you are at increased risk of developing post-thrombotic syndrome. Your doctor will determine the best treatment plan for you. This usually involves taking anticoagulant medication for several months or longer.
How do I take care of myself?
Your doctor will give you instructions on how to take care of yourself while you're at home. Follow those instructions carefully, and ask questions if anything is unclear. You can usually do things like this:
- Take your medicine exactly as prescribed .
- Keep your legs elevated when sitting or lying down.
- Avoid sitting for long periods of time as much as possible. Take short breaks to walk around and stretch your body.
- Use moisturizer to keep your skin healthy.
It's also important to take care of your mental health . Living with Post-Thrombotic Syndrome can be mentally and emotionally stressful. People with this condition can experience depression, anxiety, and low self-esteem. They may worry about having another blood clot. They may also feel sad because they can no longer do things they used to do because of their symptoms.
If you are experiencing these feelings, talking to a counselor or therapist can be a great help. They can help you deal with these feelings and find solutions that make you feel better.
When should I see my doctor?
Your doctor will give you follow-ups to monitor your condition. It is very important to attend all of these appointments so that your doctor can adjust your treatment plan as needed.
If you develop any new symptoms or if your symptoms change , call your doctor immediately.
What questions should I ask my doctor?
These questions will help you learn more about your diagnosis:
- Do I really have Post-Thrombotic Syndrome? If so, how serious is it?
- What treatments do you recommend for me?
- What changes do I need to make in my lifestyle?
- What exercises are suitable for me?
- What will my outlook be?
When you receive a diagnosis of Post-Thrombotic Syndrome, you may have many questions and fears. But don't worry, your doctor is there to answer your questions and guide you through treatment. Although this condition is common, your needs and concerns are unique. Work with your doctor to find resources that support your physical and mental health.
