Overview
Thrombus formation usually starts in the calf veins, then progresses to the proximal veins and then ultimately to the pulmonary artery leading to pulmonary embolism. Most of the times, calf DVT's are assymptomatic.
Natural History
- Untreated proximal DVT
- Clinical PE occur in 1/3rd to 1/2 patients.
- Subclinical PE occurs in another 1/3rd.
- Untreated PE tends to recur in days to weeks.
- Post-phlebitic syndrome(10-30% of DVT)
- Pain, edema, skin discoloration, and ulceration associated with chronic venous insufficiency.
Death occurs in about 6 percent of DVT cases within one month of diagnosis. [1]
According to a study done on 826 patients in Medical University of Vienna the risk of recurrence was almost four times as great among men as among women.[2]
Complications
Proximal vein thrombosis is responsible for more than ninety percent of acute pulmonary embolism which has high mortality if not treated promptly. [3]
The major outcomes of venous thrombosis are
- Recurrence,
- Major bleeding due to anticoagulation,
- Death.
Other complications include:
- Post-thrombotic syndrome,
- Phlegmasia alba dolens,
- Phlegmasia cerulea dolens,
- Lemierre syndrome
- Septic pelvic thrombophlebitis
Thrombosis is also associated with impaired quality of life, particularly when post-thrombotic syndrome develops[4]. Death occurs within one month of an episode in about 6% of those with DVT and 10% of those with PE
