摘要

目的:本研究的目的是评估计算机断层扫描(CT)对胸骨正中切口心血管手术后纵隔炎的诊断效果。材料与方法:122例患者分为两组:早期组(术后21天)。其中6例患者最终诊断为感染性纵隔炎。评估每位患者的CT表现。纵隔积液或游离气泡被认为是纵隔炎的主要表现。结果:早期组原发性CT表现的敏感性为100%,特异性为39%。晚期组的敏感性为100%,特异性为85%。6例纵隔炎患者均有纵隔积液。结论:术后早期纵隔积液或游离气泡不具有特异性。然而,在21天后,这些观察结果可能表明存在纵隔炎。

Infectious mediastinitis after cardiovascular surgery: role of computed tomography.

Purpose: The aim of this study was to evaluate the effectiveness of computed tomography (CT) findings in the diagnosis of mediastinitis after cardiovascular surgery with median sternotomy.

Material and methods: A total of 122 patients were divided into two groups: the early group (21 days after surgery). Among them, six patients were ultimately diagnosed with infectious mediastinitis. CT findings in each patient were evaluated. Mediastinal fluid collections or free gas bubbles were regarded as the primary findings of mediastinitis.

Results: In the early group, sensitivity and specificity of the primary CT findings were 100% and 39%, respectively. In the late group, the sensitivity was 100% and the specificity 85%. Mediastinal fluid collections were observed in all six patients with mediastinitis.

Conclusion: Mediastinal fluid collections or free gas bubbles are not specific during the early postoperative period. However, after 2 21 days, these observations could be indicative of mediastinitis.
