Overview

Thrombus formation typically begins in the calf veins and naturally progresses to the proximal veins and ultimately, breaks free from the site formation and travels to the pulmonary artery where it is called a pulmonary embolism. In many cases, patients with a thrombus can be asymptomatic until it progresses into the proximal veins.

Natural History

  • Many patients with a deep vein thrombosis (DVT) originating in the calf veins are asymptomatic until proximal vein involvement.[1] However, even assymptomatic DVTs are associated with increased risk of death[2].
  • About half of all calf DVTs resolve spontaneously, without intervention.[1]
  • One-sixth of all calf DVTs progress to involvement with the proximal veins.[1]
  • Typical onset of thrombus formation may occur during the intraoperative period though there is a potential latent onset up to many months after the initial surgery.[1]
  • Surgeries characteristically responsible for thrombus formation include:
  • Knee replacement surgery is associated with twice the frequency of asymptomatic onset.[1]
  • Without treatment, one-fourth to one-third of symptomatic, isolated distal thrombi in the deep veins involve proximal veins.[1]
    • Patients with isolated calf DVT treated with five days of heparin therapy without a tandem oral anticoagulant therapy were at highest risk for recurrent or extension of DVT within three months of follow-up.[1]
  • Patients with untreated DVT have the potential to develop:
  • Mortality rates associated with venous thrombosis can be very high.
    • In one study, 6% of patients with DVT died within one month of diagnosis.[3]
    • Other research suggests that approximately one-fourth of all patients die within one year of venous thrombosis onset.[1]
    • Patients presenting with a venous thrombosis consistently have higher in-hospital mortality rates.[1]

Rule of 30's

  • 30% will die in 30 days.
  • 30% will have recurrence in 10 years. The actual number at 10 years has been reported to be 36%[4]
  • 30% will develop post phlebitic syndrome.

Complications

Venous thrombosis may lead to any of the following major complications:

  • Recurrence may occur unevenly across the sexes; with men being almost four times more likely than women for a venous thrombosis recurrence.[5]
  • Major bleeding due to anticoagulation
  • Death - Proximal vein thrombosis is responsible for more than ninety percent of acute pulmonary emboli. Acute PE is ultimately associated with a high mortality if not treated promptly. [6]

Other complications include:

The rate of complications in lower extremity DVT is higher from that in upper extremity DVT. Shown below is a table summarizing the differences in the rate of occurrence of complications.[8]

Complications Upper extremity DVT Lower extremity DVT
Pulmonary embolism 6% 15-32%
Recurrence of DVT 2-5% 10%
Post thrombotic syndrome 5% 56%

Prognosis

Probability of recurrence can be estimated with the HERDOO2 rule:[9]

  • Hyperpigmentation
  • Edema
  • Redness in either leg
  • D-dimer level ≥250 μg/L
  • Obesity with body mass index ≥30
  • Older age, ≥65 years

Per the authors, "Women with a first unprovoked VTE event and none or one of the HERDOO2 criteria have a low risk of recurrent VTE and can safely discontinue anticoagulants after completing short term treatment."[9]
