  • Description: <jats:sec><jats:title>Background</jats:title><jats:p> The incidence and clinical significance of pulmonary residual thrombosis 6 months after an acute pulmonary embolism (PE) are still not well-known. </jats:p></jats:sec><jats:sec><jats:title>Purpose</jats:title><jats:p> To evaluate the association between residual vascular obstruction and the risk of venous thromboembolism (VTE) recurrence or death. </jats:p></jats:sec><jats:sec><jats:title>Material and Methods</jats:title><jats:p> Computed tomography pulmonary angiography (CTPA) was repeated in 97 consecutive patients 6 months after an acute episode of hemodynamically stable pulmonary embolism. We assessed the long-term consequences of residual thrombosis on vital status and incidence of recurrent VTE. </jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p> Six patients were lost for follow-up. The remaining 91 patients were classified according to the presence (Group 1: 18 cases) or absence (Group 2: 73 cases) of residual pulmonary vascular obstruction. After a mean ± SD of 2.91 ± 0.99 years, there were eight (8.8%) deaths and 11 (12.1%) VTE recurrences. Groups 1 and 2 did not differ in the incidence of death or VTE recurrence. </jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p> Persistent pulmonary vascular obstruction on 6-month CTPA did not predict long-term adverse outcome events. </jats:p></jats:sec>
