Asymptomatic DVT is not considered an indication for endovascular intervention at this time. The incidence of PTS at 5 years after asymptomatic calf or proximal DVT is low, at 5%. [13] The absence of symptoms may reflect the lack of the obstructive effect that is proposed to initiate the syndrome. On the other hand, while the incidence of PTS may not warrant endovascular treatment, some reports suggest that treatment of asymptomatic DVT may be necessary to prevent most cases of PE that are diagnosed at autopsy. Asymptomatic proximal DVT had a mortality risk of 13.7% versus 2% in patients without DVT.
