Introduction: Recognition of risk factors in different high-risk groups such as smokers in comparison with non-high risk groups would help to develop good preventive strategies for pulmonary thromboemboli (PTE). The purpose of this study was investigation and compare for clinical finding and risk factors in smoker and nonsmoker patients with pulmonary thromboemboli and investigation the anatomical variant in pulmonary computerized tomography angiographies.

Methods: In this descriptive study 260 consecutive patients suspected to have PTE underwent pulmonary computerized tomography angiographies in a training hospital since 2015 to 2018. Patient with documentedPTE were enrolled including smokers and non-smokers. The clinical finding and risk factors among them were determined and compared.

Results: The results in this study demonstrated that among 260 patients 172 subjects (66.15%) had PTE and enrolled in the study. 56 (32%) were smoker and 116 (68%) were non-smoker. The smoker group was younger and male gender was more prevalent. The oxygen saturation and inspired oxygen partial pressure were differed factors between smokers and non-smokers (P < 0.05). The predisposing factors of theromboemboli and the anatomic disterbution of emboli was the same in smokers and non smokers.

Conclusion: Totally, according to the obtained results it may be concluded that regarding different factors responsible for PTE in smokers and non-smokers, the clinical presentation and anatomic distribution of PTE are comeparble.
