Overview

DVT is divided on the the basis of site of occlusion:

• Upper extremity DVT: DVT of upper limb.
• Lower extremity DVT: DVT of lower limb. DVT of the lower extremity is subdivided into two categories:
  • Proximal vein thrombosis.
  • Distal (calf) vein thrombosis, in which thrombi remain confined to the deep calf veins.

Proximal vein thrombosis

Proximal vein thrombosis occurs when thrombosis involves the proximal veins like popliteal, femoral, or iliac vein. 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.
