Overview
Deep vein thrombosis is classified based on the site of occlusion or clot formation. Symptom presentation and complication is largely influenced by location of the embolus.
Classification based on site of thrombus formation
- Upper extremity DVT: DVT of the upper limbs.
- Lower extremity DVT: DVT of the lower limbs, which is subdivided into two categories:
- Proximal vein thrombosis.
- Distal (calf) vein thrombosis.
Proximal vein thrombosis
Proximal vein thrombosis involves the proximal veins like popliteal, femoral, or iliac vein. Proximal vein thrombosis is responsible for more than ninety percent of acute Pulmonary embolism and thus higher mortality. [1] Clinically, proximal vein thrombosis is of greater importance as it is more commonly associated with serious, chronic diseases like:
- Active cancer.
- Congestive heart failure.
- Old age (greater than 75 years).
- Respiratory insufficiency.
Distal vein thrombosis
Distal vein thrombosis is confined to the deep calf veins. It is often associated with transient risk factors like travel, prolonged immobilization and recent surgery.[1]
