Thromboembolic Disorders
VTE Toolk i t
• Acute coronary syndrome, ischemic or cardioembolic stroke, venous thromboembolic disease, acute limb ischemia• Acute vascular diseases are the commonest cause
of death• VTE (DVT, PE) 3rd commonest vascular disease• More deaths from PE than AIDS, breast cancer
and motor vehicle crashes combined• Risk of VTE increases with age

Thromboembolic Disorders
VTE Toolk i t
• Affects approximately 1/1,000 people annually • DVT alone accounts for 300,000–600,000 hospitalizations each year in the USA• PE causes nearly 200,000 deaths per year in the USA• Major costs of diagnosis, treatment

Risk Factors• Surgery• Trauma (major trauma
or leg injury)• Immobilization
(bedrest, stroke, paralysis)• Cancer and its
treatment (CTX, RTX, hormonal)• Acute medical illness
(heart or respiratory
failure, infection, inflammation)• Previous DVT or PE• Increased age• Estrogen use (BCP,
HRT), pregnancy, postpartum• Central venous lines • Blood clotting disorders
(thrombophilia)
