Bibliography: Mismetti et al237 There is uncertainty whether these patients should be anticoagulated for two reasons. First, because the abnormalities are small, a diagnosis of subsegmental PE is more likely to be a false-positive nding than a diagnosis of PE in the segmental or more proximal Second, because a true subsegmental PE is likely to have arisen from a small DVT, the risk of progressive or recurrent VTE without anticoagulation is expected to be lower than in patients with a larger PE.110,111,117,118 Our literature search did not identify any randomized trials in patients with subsegmental PE. There is, however, high-quality evidence for the ef cacy and safety of anticoagulant therapy in patients with larger PE, and this is expected to apply similarly to patients with subsegmental PE.1 Whether the risk of progressive or recurrent VTE is high enough to justify anticoagulation in patients with subsegmental PE is There were no episodes of recurrent VTE in retrospective reports that included about 60 TABLE 17 ] Summary of Findings: Elastic Compression Stockings vs No Elastic Compression Stockings to Prevent PTS of the Leg Outcomes No.
