Hemothorax

Abstract: Objective: Given its importance in trauma practice, we aimed to determine the pathologies associated with blunt chest injuries and to analyze the accurate identification of patients at high risk for major chest trauma. Methods: We reviewed our experience with 1490 patients with blunt chest injuries who were admitted over a 2-year period. Patients were divided into three groups based on the presence of rib fractures. The groups were evaluated to demonstrate the relationship between the number of rib fractures and associated injuries. The possible effects of age and Injury Severity Score (ISS) on mortality were analyzed. Results: Mean hospitalization time was 4.5 days. Mortality rate was 1% for the patients with blunt chest trauma, 4.7% in patients with more than two rib fractures and 17% for those with flail chest. There was significant association between the mortality rate and number of rib fractures, the patient’s age and ISS. The rate of development of pneumothorax and/or hemothorax was 6.7% in patients with no rib fracture, 24.9% in patients with one or two rib fractures and 81.4% in patients with more than two rib fractures. The number of rib fractures was significantly related with the presence of hemothorax or pneumothorax. Conclusion: Achieving better results in the treatment of patients with chest wall injury depend on a variety of factors. The risk of mortality was associated with the presence of more than two rib fractures, with patients over the age of 60 years and with an ISS greater than or equal to 16 in chest trauma. Those patients at high risk for morbidity and mortality and the suitable approach methods for them should be acknowledged. q 2002 Elsevier Science B.V. All rights reserved.

Abstract: Computed tomography (CT) was used to guide percutaneous fine-needle biopsy in 150 cases of difficult thoracic lesions; in 76 cases, nondiagnostic bronchoscopy (n = 62) and fluoroscopic biopsy (n = 14) had previously been performed. CT was indicated for guidance when the pulmonary or pleural lesions were small (0.3-2.5 cm); in a juxta-vascular location, either hilar or mediastinal; not seen or poorly visualized on conventional radiographs; or considered inaccessible. A diagnosis was made in 124 of 150 cases (82.7%) (107 of 124 malignant and 17 of 26 benign lesions), including 86 of 107 lung nodules (80.4%), 28 of 31 mediastinal lesions (90.3%), and ten of 12 pleural masses (83.3%). Complications included pneumothorax (n = 64), hemoptysis (n = 5), hemothorax (n = 2), and pericarditis (n = 1). The high rate of pneumothorax, its treatment, and advantages of its immediate radiologic management are discussed. Use of CT guidance considerably expands the scope of thoracic lesions amenable to percutaneous biopsy.

Abstract: STATEMENT OF THE PROBLEMThoracic trauma is a notable cause of morbidity and mortality in American trauma centers, where 25% of traumatic deaths are related to injuries sustained within the thoracic cage.1 Chest injuries occur in ∼60% of polytrauma cases; therefore, a rough estimate of the occurrence
