Deep Venous Thrombosis (DVT)
Prognosis for Deep Venous Thrombosis
Without adequate treatment, lower extremity DVT has a 3% risk of fatal PE ( Prognosis references ); death due to upper extremity DVT is very rare. Risk of recurrent DVT is lowest for patients with transient risk factors (eg, surgery, trauma, temporary immobility) and greatest for patients with persistent risk factors (eg, cancer), idiopathic DVT, or incomplete resolution of past DVT (residual thrombus). A normal D-dimer level obtained after anticoagulation is stopped for 3 to 4 weeks may help predict a relatively low risk of DVT or PE recurrence, more so in women than in men. Risk of venous insufficiency is difficult to predict. Risk factors for post-thrombotic syndrome include proximal thrombosis, recurrent ipsilateral DVT, and body mass index (BMI) 1.Yamashita Y, Murata K, Morimoto T, et al.
