| 摘 要： | 目的探讨CT对迟发性肺挫伤的诊断意义及其动态表现,为临床及时准确治疗提供可靠的诊断依据。方法分析150例迟发性肺挫伤的CT和临床资料,对迟发性肺挫伤与发生时间、发生部位、与既往肺部疾病以及迟发性血胸的相关性进行研究,对迟发性肺挫伤的CT表现及其动态变化等进行分析。结果根据CT表现将迟发性肺挫伤分为:分支型51例:病灶沿支气管分布,呈分支状;粗大条索型40例:表现为肺外带粗大条索状高密度影,长短不一;絮带型33例:挫伤病灶沿肺叶边缘分布,表现为沿两肺外带絮带状高密度影;新月型26例:表现为下叶背部近胸膜下新月状毛玻璃样密度影,大都单侧发生。迟发性肺挫伤大都于伤后24h后～48h内发生,达62.00%(93/150),与伤后～24h内以及48h后～72h内比较差异有极显著性意义(P0.0001);大都发生在右肺,占64.97%(97/150),与发生在左肺比较,差异有极显著性意义(P0.0001),发生在下叶的迟发性肺挫伤又比上叶明显多见,差异也有极显著性意义(P0.0001)。结论CT不仅能及时发现迟发性肺挫伤,还可对发生的部位、性质、损伤程度、并发症以及预后等做出及时判定,为临床及时准确治疗提供可靠的诊断依据;应将伤后48hCT复查列为常规;迟发性肺挫伤不易完全吸收,易遗留肺纤维化及胸膜增厚、粘连。

| Abstract: | Objective To explore the value of the Computed Tomography(CT) scanned images and the dynamic change in diagnosis of pulmonary contusion. Methods 150 patients with pulmonary contusion were analyzed. The CT image and the clinical data was collected, and analyzed the correlativity between delayed pulmonary contusion and the occurred time, the position, previously lung disease or the delayed hemopneumothorax. The CT manifestation and the dynamic change of the delayed pulmonary contusion was analyzed simultaneou... |
