Desfechos Clínicos após Investigação para Embolia Pulmonar Utilizando TC de Tórax/Membros Inferiores Clinical Outcomes after Investigation for Pulmonary Embolism using CT Angiography and Venography

摘要: Background: The diagnosis of pulmonary embolism (PE) still requires long work-up periods and multiple tests. Objective: We aim to assess clinical outcomes after a negative investigation using combined protocol CT angiography venography (CTA/CTV) as sole diagnostic test in unselected patients with suspected PE. Methods: This retrospective cohort study enrolled consecutive PE who were investigated CTA/CTV protocol. Patients had an initially not anticoagulated followed for 6 months the occurrence recurrent venous thromboembolic events. Results: Out 425 PE, 62 (14.6%) thromboembolism diagnosed on initial CTA/CTV. mean age was 56 ± 19 years 61% population fell into low probability category. Isolated deep vein thrombosis represented 21% all events, when considering whole population, CTV associated increment yield 3.1%. Our composed 320 CTA/CTVs anticoagulated. After follow up, only three presented events (0.9%; 95% CI -0.1% - 2.0%) none fatal. There no PE-related deaths. Conclusion: suggests that strategy utilizes can safely rule out moderate risk is favorable predictive value 99.1%. (Arq Bras Cardiol. 2012; [online].ahead print, PP.0-0)
