[Abstract] Objective To explore the X-ray, CT findings of blunt chest trauma, in order to improve the diagnostic accuracy rate. Methods 106 cases of blunt chest injury in patients with clinical data, X-ray and CT findings from 2010 to 2012 were retrospectively analyzed. Results By X-ray and CT examination, pulmonary parenchyma injuryblunt by chest trauma caused showed complex injuries, including 94 cases of pulmonary contusion (traumatic wet lung), 6 cases of lung laceration. Among them,61 cases with rib fractures, 29 cases with pleural effusion (blood), 21 cases with pneumothorax, 11 cases with soft tissue product gas, 4 cases with pulmonary hematoma, 2 cases with lung cysts and 2 cases with pericardial effusion. Conclusion Early blunt chest trauma imaging is helpful to find the lesion site, the nature and extent of damage, CT is helpful to find complications.

胸部在直接或間接暴力作用下,均有發(fā)生開放性或閉合性肺實(shí)質(zhì)損傷的可能,包括肺挫傷/創(chuàng)傷性濕肺、肺撕裂傷。肺實(shí)質(zhì)損傷在平片、CT上可有多種形式的改變,此與致傷種類、強(qiáng)度、時(shí)間長短以及致傷部位與范圍都有一定的關(guān)系,故其表現(xiàn)各異。本資料收集胸部閉合性創(chuàng)傷106例影像資料,分析所致肺實(shí)質(zhì)損傷的影像特點(diǎn)。
