Thrombosis is a condition where a blood clot forms inside a blood vessel, restricting or stopping blood flow. It has two main categories: venous thrombosis, where a clot forms in a vein, and arterial thrombosis, where a clot forms in an artery. Thrombosis can be caused by abnormalities in blood coagulation, injuries to blood vessels, or slowed blood flow. Risk factors include inherited blood disorders, prolonged bed rest, obesity, smoking, cancer, and pregnancy. Symptoms vary depending on the location and severity of the clot. Treatment involves anticoagulant medications, compression stockings, filters, endovascular procedures, or surgery.

Thrombosis
Also Known As: Blood Clot
What is Thrombosis?
Thrombosis is a general term describing the condition that occurs when a blood clot develops within a blood vessel, causing the
blood flow to be restricted or completely stopped. This blockage causes pressure to build up, and can result in very serious life
threatening issues.
The two main categories of Thrombosis are:
• Venous Thrombosis: When a blood clot forms in a vein
• Arterial Thrombosis: When a blood clot forms in an artery
Causes
Virchow’s Triad (or the Triad of Virchow), describes the three broad categories that are thought to contribute to Thrombosis:
• Hypercoagulability: Abnormalities in blood coagulation, fibrinolytic pathways and in platelet function
• Vascular Wall Injury/Dysfunction: Injuries and/or trauma to the interior lining of blood vessels
• Circulatory Stasis: The slowing or stopping of blood flow
Factors that can increase the risk of developing some form of Thrombosis include:
• Inheriting a blood-clotting disorder
• Prolonged bed rest, such as during a long hospital stay, or paralysis
• Injury or surgery
• Pregnancy
• Birth control pills (oral contraceptives) or hormone replacement therapy
• Being overweight or obese
• Smoking
• Cancer and cancer treatments
• Heart failure
• Inflammatory Bowel Diseases
• May-Thurner Syndrome
• A personal or family history of deep vein thrombosis or pulmonary embolism
• Sitting for long periods of time, such as when driving or flying.
Symptoms
The symptoms of Thrombosis vary depending on the area affected and the severity of the condition.
If a person notices any symptoms of Thrombosis, it is crucial to seek immediate medical attention, because severe life-threatening
complications can occur.
Diagnosis & Treatment
Thrombosis is diagnosed by a Doctor using a physical examination and blood tests.
Depending on the type of Thrombosis, the Doctor may also order the following tests:
• CT Scan
• Ultrasound Scan© 2018 – 2028 Mediv8. All Rights Reserved.

2. • D-Dimer blood test
• Venogram
• Electrocardiogram (ECG)
The exact type and stage of the Thrombosis will determine the treatment used. The main treatments include:
• Anticoagulant Medications
• Antiplatelet Medications
• Compression stockings
• Inferior Vena Cava Filter
• Endovascular treatment
• Surgery
• Thrombolytic Medications
Additional Information
There are various types of Thrombosis that can occur in the veins and arteries, including:
• Deep Vein Thrombosis (DVT)
• Superficial Vein Thrombosis (SVT)
• Pulmonary Embolism (PE)
• Femoral Vein Thrombosis
• Effort Thrombosis
• Myocardial Infarction (Heart Attack)
• Superior Vena Cava Syndrome
• Jugular Vein Thrombosis
• Thrombotic Stroke
• Cerebral Venous Sinus Thrombosis
• Cavernous Sinus Thrombosis
• Retinal Vein Occlusion
• Portal Vein Thrombosis
• Budd-Chiari Syndrome
• Renal Vein Thrombosis
• Critical limb Ischemia (CLI)
