| Abstract

Background : It is suggested that combination use of imaging and clinical findings as well as evaluation of patients' risk factors would be more helpful for proper risk stratification for early diagnosis and treatment of Pulmonary thromboembolism ( PTE ). In this study, the correlation between CTPA findings with risk factors , clinical and echocardiography findings of patients refer from different wards of our hospital with suspected acute PTE were determined. Methods : In this cross sectional study, hospitalized patients aged 18 years or older with high clinical suspicion of PTE referred to imaging center of our hospital from different wards for CTPA , were enrolled. The frequency of different clinical presentations, risk factors, items of Wells criteria and echocardiographic findings were compared in patients with and without PTE which have been diagnosed according to the CTPA results.Results : In this study, 310 patients with mean age of 56.78(18.20) years who suspected to PTE were studied. According to the CTPA results, PTE was diagnosed in 53(17.1%) of patients. From clinical manifestations tachypnea , pleuritic chest pain and edema of lower extremities were significantly more frequent among patients with PTE than those without ( P < 0.05 ). Major surgery was the risk factor which was significantly more prevalent among patients with PTE ( P < 0.05 ).Frequency of all criterion of Wells criteria except hemoptysis were significantly higher in patients with PTE than those without ( P < 0.05 ). The frequency of all studied echocardiographic variables were significantly higher in patients with PTE than those without ( P < 0.05 ).The highest numbers of referrals were from emergency, pulmonary, surgery wards, intensive care unit (ICU) and obstetrics departments, in order. The proportion of positive PTE was higher in surgery ( 51.9% ) and orthopedics ( 40% ) wards , respectively. The rate of negative CTPA results was higher in ENT ( 100%) and obstetrics (96.2%) wards, respectively. Conclusion : Our findings indicated that the proportion rate of positive CTPA results from those referred with suspicious findings of PTE was low in some of the departments of the hospital, which emphasize on revising our diagnostic protocols for PTE. On the other hand, considering the association of some risk factors and clinical, imaging and echocardiographic findings with the results of CTPA , it is suggested that we could use the results of this study for utilizing the diagnostic process of PTE in patients with highly clinical suspicion of PTE and providing more validated decision.
