What is Thrombosis
Thrombosis occurs when a blood clot forms inside a blood vessel or heart chamber. These clots can obstruct blood flow in vessels or detach and travel to other parts of the body. If a clot lodges in a critical area such as the lungs or brain, it can lead to a life-threatening emergency by disrupting blood flow to the affected organ. Symptoms vary depending on the clot’s location and may include chest pain, difficulty breathing, and changes in skin appearance.
Certain individuals are at a higher risk of thrombosis due to medical conditions or other factors. Understanding your risk can aid in prevention, while awareness of symptoms can help detect issues promptly if they arise.
Types of thrombosis
Thrombosis manifests in two primary types:
Arterial thrombosis: Occurring when a blood clot forms within an artery, typically those carrying blood from the heart to the rest of the body. Arterial thrombosis is a leading cause of heart attacks and strokes.
Venous thrombosis: This type develops when a blood clot forms within a vein, which is responsible for returning blood from the body to the heart. Venous thrombosis is the primary cause of pulmonary embolisms, where a blood clot lodges in the lung.
Thrombosis poses a significant risk regardless of its location, as it can:
- Cause blockages at the site of formation, potentially growing in size until it obstructs blood flow. The severity of this blockage depends on the location and size of the clot.
- Trigger secondary blockages elsewhere in the body. When a clot detaches and becomes an embolus, it can travel through the bloodstream and lodge in smaller blood vessels, causing an embolism. Such events often lead to conditions like stroke and pulmonary embolism.
What are the symptoms of thrombosis?
Thrombosis symptoms vary depending on factors such as the clot’s size, location, and resulting complications. Blockages are more likely to occur in areas with tiny blood vessels, notably the lungs, brain, and the deeper regions of the legs and arms. Below are common symptoms associated with each location:
Lungs (pulmonary embolism):
- Sharp chest pain, extending to adjacent areas like the jaw, neck, shoulder, back, or arm.
- Pain exacerbated by breathing in.
Brain or neck (transient ischemic attack or stroke):
- Weakness or difficulty controlling muscles on one side of the body.
- Slurred or unclear speech.
Heart (heart attack):
- Chest pain or discomfort, often described as angina.
- Breathing difficulties.
- Dizziness or loss of consciousness.
Belly (mesenteric ischemia):
- Severe abdominal pain, particularly after eating.
- Bloating, accompanied by nausea and vomiting.
- Diarrhea, potentially containing blood.
- Fever.
Artery in arm or leg:
- Paler skin in the affected area.
- Coolness to the touch.
- Weakness and limited movement in the affected limb.
Vein in arm or leg:
- Redder or darker skin tone in the affected area.
- Pain, especially around the site of the clot.
How is thrombosis treated?
Treatment for thrombosis encompasses various approaches, including medications, minimally invasive procedures, and surgical interventions. Your healthcare provider will customize the treatment plan based on your specific needs.
Potential treatments include:
-
Anticoagulation: These medications prevent excessive blood clotting.
-
Thrombolytic therapy: This involves using medications to dissolve blood clots, particularly beneficial for clots in critical areas. Known as “clot-busting drugs,” they are crucial emergency treatments for conditions like heart attacks, strokes, and other thrombosis-related complications.
-
Thrombectomy: This procedure directly removes a clot by surgical access. Surgeons utilize either open or minimally invasive techniques to access and extract the clot.
Additional treatments may be necessary to address complications arising from thrombosis. Your healthcare provider will provide insights into any additional treatments required and their rationale.
