Conservative treatment and thoracostomy are the most common treatments and succeed in almost all cases, while the rest require thoracotomy. Follow-up care is necessary to perform strategy changes immediately for the best overall results. Objectives: To study the clinical, imaging features, and treatment results of hemothorax in blunt chest trauma. Materials and methods: A prospective descriptive study of 41 patients with hemothorax was conducted at the Department of Thoracic Surgery, Can Tho General Hospital, from April 2022 to December 2022. Results: The mean age was 53.24 ± 8.97; 70.73% were male; traffic accident was the most common cause (73.17%); chest pain and dyspnea were the two most frequent symptoms, accounting for 97.56% and 48.78%, respectively; the syndrome of decreased breath sounds, dullness to percussion and decreased tactile fremitus was found in 78.05%. The mean number of rib fractures was 4.24 + 2.29; the most common ribs fractured were the 4th through 10th ribs (53.66%); hemothorax and hemopneumothorax accounted for 75.61% and 24.39%, respectively; 28 patients (68.29%) received conservative treatment, in which three patients (10.71%) worsing then received pleural drainage, as a whole, 16 patients in total received pleural drainage treatment; the overall treatment success rate was 97.56%, and 1 case (2.44%) had a complication of empyema; the length of hospital stay was 7.29  2.69 days and differed between the two groups of patients with minimal hemothorax and other hemothorax (p=0.049). Conclusions: Chest pain and dyspnea were the most common clinical symptoms; conservative treatment is common and follow-up is important; the overall treatment success rate was 97.56% and the length of hospital stay was 7.29  2.69 days.
