How Many Types of DVTs?

Provoked DVTs occur in association with acquired risk factors, such as surgery, oral contraceptives, trauma, immobility, obesity, or cancer; cases without acquired states are called unprovoked or idiopathic.

Acute DVT is characterized by pain and swelling and is usually occlusive, which means that it obstructs blood flow, whereas non-occlusive DVT is less symptomatic. The label “chronic” has been applied to symptomatic DVT that persists longer than 10 to 14 days.DVT that has no symptoms, but is found only by screening, is labeled asymptomatic or incidental.

DVT in the legs is proximal (or iliofemoral ) when above the knee and distal (or calf ) when below the knee.

DVT below the popliteal vein, a proximal vein behind the knee, is classified as distal and has limited clinical significance compared to proximal DVT.An initial episode of DVT is called incident and any subsequent DVT is termed recurrent.

Bilateral DVT refers to clots in both legs while unilateral means that only a single leg is affected.
