    [Abstract] Objective To evaluate the features of CT findings in chronic thromboembolic pulmonary hypertension.Methods Retrospective analysis on spiral CT imaging of chronic thromboembolic pulmonary hypertension proved by clinical treatment in 10 cases which underwent CT plain scanning and enhanced scanning were performed.Results Enlargement of main pulmonary artery in 10 cases,ventricular septal shift in 1 cases,vena cava regurgitation in 3 cases,peripheral pulmonary embolism in 2 cases were found,hybrid pulmonary embolism in 8 cases.Conclusion The imageological manifestation of chronic thromboembolic pulmonary hypertension are specific. ......
