If the thrombus that embolizes is small (which is frequently the case when it is located in the calf), the embolus is usually asymptomatic and clinically insignificant, although the cumulative effect, if there are repeated showers of small emboli, can cause cor pulmonale.The dose is then adjusted to maintain the activated partial thromboplastin time (aPTT) at the upper limit of the normal range.Treatment of Acute Deep Venous Thrombosis and Pulmonary Embolism.Because of their fear of recurrent venous thrombosis, patients often become concerned if they develop even minimal exacerbations of symptoms or signs.Anticoagulation reduces mortality and recurrence in patients with acute PE and reduces recurrence in patients with DVT. 143 144 145.
