Our Areas Of Research For Thrombosis
For many children with rare or hard-to-treat conditions, clinical trials provide new options. Participation in any clinical trial is completely voluntary. We will take care to fully explain all elements of the treatment plan prior to the start of the trial, and you may remove your child from the medical study at any time. Currently, our hematology team is studying several new oral blood thinners in children for treatment and prevention of blood clots. We are also involved in an international study of the length of anticoagulation needed to treat thrombosis. Your hematologist may mention opportunities to participate in these studies, but you should feel free to ask about current research studies relevant to your child.
Researchers at Dana-Farber/Boston Childrens perform scientific and clinical research on platelets and related aspects of hemostasis and thrombosis. A particular focus is antiplatelet therapy, including the characterization of:
- how newly discovered molecules and mechanisms could help control platelets and clotting
- how antiplatelet drugs affect normal blood clotting and aspects of the immune system
- the relationship between the strength of antiplatelet treatments and the balance between thrombosis and hemorrhage
- how tests of platelet function could help guide antiplatelet therapy in the clinic
What Are The Symptoms Of Axillo
Symptoms of ASVT may include:
- Cyanosis, or bluish tint to the skin of your arm.
- Heaviness or fatigue in your arm.
- Sudden swelling in your arm.
In 10% to 20% of cases, the clots can dislodge from upper arm veins and travel to your lungs. This clot is called a pulmonary embolism . A PE can cause serious lung damage or even death.
Treatment For Blood Clots
If you have been told you have a blood clot, your doctor may give you medicine to treat it. This type of medicine is called a blood thinner . In most cases, your doctor will tell you to follow this treatment plan:
- For the first week you will receive medicine called heparin that works quickly.
- This medicine is injected under the skin. You will learn how to give yourself these shots, or a family member or friend may do it for you.
- You will also start taking Coumadin® âgeneric name: warfarin âpills by mouth. After about a week of taking both the shots and the pills, you will stop taking the shots. You will continue to take the Coumadin®/warfarin pills for about 3 to 6 months or longer.

What Are The Causes Of Broken Blood Vessels On Arm

- Broken Blood Vessels on Arm caused by Injury/Trauma: Injury is the commonest cause of broken blood vessels in the arms. The injury could be from a fall or banging against furniture which leads to rupturing of the blood vessels in the arm.
- Broken Blood Vessels on Arm caused by Medications: Medications is another cause for broken blood vessels in the arm. There are certain drugs which make the capillaries fragile and weak, resulting in rupture of the capillaries with only slight pressure. This especially occurs when the patient is given an injection on the arm.
- Broken Blood Vessels on Arm caused by Aging: Aging increases the fragility of the skin which in turn makes the capillaries delicate hence the blood vessels on arm break easily with little pressure.
- Broken Blood Vessels on Arm caused by Fracture: This is another common cause for broken blood vessels in arm. If fracture is the cause, then the broken blood vessels may be deeply seated accompanied with severe pain.
- Broken Blood Vessels on Arm caused by Medical Conditions: Medical conditions like blood dyscrasias and liver failure can also cause broken blood vessels in arm in some people.
- Broken Blood Vessels on Arm caused by Weather: Extreme hot and cold weather conditions may also break the superficial blood vessels.

Blood Clot In Arm Symptoms Causes Diagnosis Treatment
We often hear people talking about blood clots but we never understand how harmful it can be. Blood clots can be dangerous at times and most of the people who suffer from a blood clot in arm tend to ignore this fact. A blood clot is a mass of blood that state of which is changed from liquid to something like a slimy gel.
Though it is understood that clotting is a process that is important as it prevents from the loss of blood during an injury, but the clots that form inside of our veins are the ones that do not get dissolved on their own. This condition can be dangerous at times and can also lead to life threatening situations.
When the blood clot is formed inside on the veins of the arm, it can be immobile and such a clot is harmless. But, with time and if not treated properly, it can move and also become dangerous at times. There are cases when the blood clot can break free and can travel via the veins to the heart and the lungs. This can thus get stuck and prevent the flow of blood, causing a medical emergency.
Who Is At Risk Of Blood Clots
Usually a combination of things leads to a blood clot. You are more likely to develop a blood clot if:
- you dont move around for a long period of time
- you arent moving because you have had surgery
- you arent moving due to an injury, especially a leg injury
- you have had a blood clot before
- you have a blood disorder or other condition that makes clotting more likely
Other factors that increase the risk of a blood clot include:
- you are taking some kinds of birth control pill

How Is Thrombophilia Classified
Thrombophilia refers to a group of disorders that increases a childs tendency to develop dangerous blood clots. There are two main types of thrombophilia:
- Inherited thrombophilia is caused by certain genetic conditions.
- Acquired thrombophilia is caused by lifestyle factors or medical conditions, including immobility, obesity, sedentary lifestyle, trauma, smoking, or oral contraceptive use.
What Causes Blood Clots
Your body reacts to an injury or cut by clotting your blood just the way it should. These types of clots are not a problem. Sometimes a blood clot will form without a trigger . This is more likely to happen with certain risk factors or conditions. Risk factors include:
- Prolonged sitting
- Prolonged bed rest
- Birth control pills/hormone replacement therapy/breast cancer medicines
- Certain cancer types
- Some types of major surgery
- A family history of blood clots
- Autoimmune disorders
- Certain infections

Whats The Outlook After Diagnosis
If you stick with your treatment plan, your overall outlook after a blood clot in your arm is good.
But blood clots can recur, especially if you need to keep a central venous catheter for ongoing treatments. If you experience any unusual symptoms, consult with a doctor.
There are several steps you can take to prevent blood clots from forming in your arms:
- Ask a doctor if youll need blood thinners or compression garments during an extended hospital stay.
- Ask a doctor how to prevent blood clots if you have a pacemaker or central venous catheter.
- Exercise regularly.
- Maintain a moderate weight.
- Dont sit still for too long. Move your feet, ankles, hands, wrists, and arms to keep your blood flowing.
- Get regular checkups to look for and treat heart disease, diabetes, and cancer.
When To See A Doctor
If you happen to experience any of the serious symptoms mentioned above, it would be a good idea to seek medical care as soon as possible. Having a blood clot in the arm may not be immediately life-threatening, but it can be an indicator of excessive clotting. This may lead to more clots elsewhere in the body that should be identified right away. The following should prompt you to see a doctor right away:
- Shortness of breath

What Is The Long
Some deep vein thromboses may resolve without treatment. Treatment is given to help get rid of the blood clot and to minimize complications of thrombosis. If the blood clot remains, other veins will enlarge to bypass the blockage. Sometimes these veins are visible, like varicose veins. After a blood clot some people develop long-term pain and swelling in the leg called post-thrombotic syndrome, which is caused by reduced blood flow and damage to the affected vein. Some patients also have changes in skin color, which may not develop for a year or more afterward.
Blood clots in the thigh are more likely to break off and travel to the lungs than blood clots below the knee or in the arms. A pulmonary embolism can be a life-threatening emergency, requiring immediate medical attention.
Types Of Broken Blood Vessels

There are two different types of broken blood vessels that may appear on your arm:
- Common bruising is the first type of broken blood vessel that appears as a purplish bruise/welt on the arm.
- Blood spot on arm is another type of broken blood vessel that appears as redness spreading in the affected area.

What Is A Pulmonary Embolism
A pulmonary embolism is a blood clot that develops in a blood vessel in the body . It then travels to a lung artery where it suddenly blocks blood flow.
A blood clot that forms in a blood vessel in one area of the body, breaks off, and travels to another area of the body in the blood is called an embolus. An embolus can lodge itself in a blood vessel. This can block the blood supply to a particular organ. This blockage of a blood vessel by an embolus is called an embolism.
The heart, arteries, capillaries, and veins make up the body’s circulatory system. Blood is pumped with great force from the heart into the arteries. From there blood flows into the capillaries . Blood returns to the heart through the veins. As it moves through the veins back to the heart, blood flow slows. Sometimes this slower blood flow may lead to clot formation.
Blood Clot In The Arm: Symptoms Causes And Home Treatment
A blood clot, also referred to as deep vein thrombosis , is the result of activated clotting factors and components found in the blood stream. Blood clots can appear in the arm, but can also present elsewhere in the body. They have a multitude of causes, but one of the most common is prolonged immobility, like in the case of a long flight. Certain conditions and risk factors may also increase the likelihood of blood clots appearing, including pregnancy, smoking, and hormone therapy.
Having the ability to recognize the symptoms of a blood clot and knowing when to seek medical attention can mean the difference between life and death. In most cases, blood clots do not pose an immediate threatif you have a blood clot in your arm, some home remedies may be able to provide some relief.

Signs And Symptoms Of Blood Clot In Arm
Blood clotting is a normal part of the body and is not necessarily harmful. If the body didnt have this ability, a simple cut would cause you to bleed out. The human body is a delicate ecosystem that is constantly analyzing and repairing damaged tissue, and this goes for blood vessels too, as they are often subjected to constant stress and trauma from blood circulation. If a blood clot forms in a blood vessel in the arm that is large, it may cut off blood circulation and present with the following symptoms:
Swelling of the affected arm: This occurs due to the buildup of blood, as it cannot proceed past the blockage.
Arm pain or tenderness: This can be initially described as a cramp. The blockage of blood to the rest of the arm can result in tissue damage. This manifests as pain in the affected area, and it may also be tender to touch.
Reddish or bluish skin discoloration: More easily identified in lighter skinned individuals, this discoloration is a hallmark sign of what a blood clot in the arm looks like.
The arm is warm to the touch: The area affected is often of higher temperature than the rest of the body. Stagnated blood may irritate the blood vessels, causing the area to become relatively warmer than the opposite arm.
Vein distension: The appearance of engorged or stretched veins. With the blood having nowhere else to go, it results in the veins of the arm stretching themselves in an attempt to accommodate the increased volume seen at the clot site.

Who Is At Risk For A Pulmonary Embolism
Risk factors for pulmonary embolism include:
-
Genetic conditions that increase the risk of blood clot formation
-
Family history of blood clotting disorders
-
Surgery or injury or orthopedic surgery
-
Situations in which mobility is limited, such as extended bed rest, flying or riding long distances, or paralysis
-
Previous history of clots
You may also have symptoms of deep vein thrombosis , such as:
-
Pain in the affected leg
-
Swelling in the leg
-
Soreness, tenderness, redness, and/or warmth in the leg
-
Redness and/or discolored skin
If your healthcare provider thinks you have a PE, he or she will check your legs for signs of deep vein thrombosis.
The type and extent of symptoms of a PE will depend on the size of the embolism and whether you have heart and/or lung problems.
The symptoms of a PE may look like other medical conditions or problems. Always talk with a healthcare provider for a diagnosis.
Can Blood Clots Be Prevented Or Avoided
Blood clots are highly preventable. To prevent or avoid a blood clot, know your personal risk factors and control the risks you can. For example, if you smoke, stop. If you are obese, lose weight. If you take birth control pills, talk to your doctor about an effective alternative. If you are inactive, get moving. If you have a family history of blood clots, talk to your doctor. Your doctor may determine whether you should be taking blood-thinning medicine to prevent clots.
There are several situations in life that increase your risk for blood clots. These include:
- When you are pregnant
- When you have just had major surgery
- When you have cancer

How To Treat Blood Clots In The Arm
Serious blood clots often require a visit to the emergency room, as they can be potentially fatal if not caught in time. Anticoagulantsthey essentially dissolve the clot and prevent new ones from formingwill probably be provided in the emergency room. These are designed to inhibit blood clot factors vital for the clotting process. Antiplatelet medication may also be used for the same reasons, but to dissolve platelets instead.
What If You Have Symptoms

If you have new symptoms indicating the possibility of a DVT or a PE, and if you cant speak immediately to your doctor or nurse, go to the emergency room. “Its an emergency, not something to check out on Monday if its Friday,” Dr. Scovell says.
Treatment typically involves taking a blood thinner for several months or longer. “We also have to figure out why you got the blood clot. If we cant find a reason, you may need to take a blood thinner for a longer time,” Dr. Scovell says. “And we dont want you to ever get a blood clot again, so youll need to be proactive about avoiding future risks.”

A Few Takeaways From This Study
This study has a few suggestions for clinicians as well as patients. We list them here.
- Clinicians should test for both deep vein thrombosis and COVID-19 in patients who present with complaints of unexplained swelling.
- Patients who test positive for COVID-19 should seek medical attention if they have declining oxygen levels, shortness of breath and any unexplained swelling.
- Be vigilant is you have an earlier diagnosis of deep vein thrombosis or any chronic medical illness that may cause blood clots. You have a higher risk for recurrence of a deep vein thrombus if you catch the COVID-19 infection.
What Is A Blood Clot
Blood clots are gel-like collections of blood that form in your veins or arteries when blood changes from liquid to partially solid. Clotting is a normal function that stops your body from bleeding too much when you get hurt. However, blood clots that form in some places and dont dissolve on their own can be dangerous to your health.
Normally, a blood clots start as a response to injury of a blood vessel. At first, the blood stays in one place. Two substances platelets and fibrin combine to form what is called a platelet plug to stop up the cut or hole.
When a blood clot forms where it should not have developed, it is called a thrombus. A blood clot is also called a thrombus. The clot may stay in one spot or move through the body . The clots that move are especially dangerous. Blood clots can form in arteries or veins .
The symptoms of a blood clot, and the recommended treatment, depend on where a clot forms in your body and how much damage it could cause. Knowing the most common blood clot signs and risk factors can help you spot or even prevent this potentially life-threatening condition.
