Risk calculators and risk factors for Deep vein thrombosis triggers

Overview

Venous thromboembolism (VTE) consists of deep vein thrombosis (DVT), pulmonary embolism (PE), or both. In these chapters on VTE, the word risk factors refers to those epidemiologic and genetic variables that expose someone to a higher risk of developing venous thrombosis. The word triggers refer to those factors in the patients immediate history or environment that may have led to the occurrence of the venous thrombosis. The triggers of VTE include injury to a deep vein from surgery, a fracture, or other trauma, especially a paralytic spinal cord injury.[1] Another trigger for VTE is prolonged immobilization that causes stasis in the deep veins which may occur after surgery, prolonged bed-rest, or prolonged seating during travel.

Triggers

Shown below is a list of triggers of VTE.[1][2] The triggers are classified as strong, moderate, or weak depending on how strongly they predispose for a VTE.

Strong triggers Moderate triggers Weak triggers
Bone fracture (hip or leg)

Hip replacement surgery
❑ Knee replacement surgery
Major general surgery
Significant trauma
Spinal cord injury

❑ Athroscopic knee surgery

Central venous lines
Chemotherapy

❑ Bed rest for more than 3 days

❑ Prolonged car or air travel
Laparoscopic surgery
❑ Prepartum

Triggers for Upper Extremity DVT

Shown below is a list of triggers for upper extremity DVT:[3]
