概括
支气管肺封存 (BPS) 可以通过分析静脉排水 (VD) 和CT扫描上的尖边缘 (SM) 来准确地分类. 缺少SM表明了内膜结 (ILS),而SM和全身VD则预测了外膜结 (ELS).
科学领域:
- 儿科手术 儿科手术
- 胸部外科手术 胸部外科手术
- 诊断成像 诊断成像 诊断成像
背景情况:
- 支气管肺结节 (BPS) 是一种先天性肺形,具有系统性动脉供应和可变静脉排水.
- 在手术规划和患者管理方面,区分内膜层隔离 (ILS) 和外膜层隔离 (ELS) 是至关重要的.
- 以前的研究表明,ILS和ELS之间有不同的静脉排水模式,但其预测价值需要进一步调查.
研究的目的:
- 在手术前CT扫描中评估静脉排水 (VD) 和利边缘 (SM) 作为分类BPS类型 (ILS与ELS) 的独立预测因素.
- 评估这些成像特征的诊断准确性,以区分ILS和ELS.
主要方法:
- 对36名儿科患者进行了回顾性审查,这些患者在2016年至2023年期间接受了BPS的胸腔镜切除.
- 在手术前的CT扫描中,分析了病变静脉排水 (VD) 和尖边缘 (SM) 的存在或不存在.
- 放射学预测与手术内胸腔镜检测结果相关,用于分类.
主要成果:
- 观察到VD的显著差异:96%的ILS流入肺静脉,而83%的ELS流入全身静脉 (p < 0.00001).
- 在CT上没有MS可靠地预测ILS (100%准确率).
- 对于ELS,MS的存在具有85.7%的积极预测值 (PPV),当与全身VD相结合时,增加到91.7%.
结论:
- 在手术前的CT上没有利的边缘,这是内腔管隔离 (ILS) 的强有力的指标.
- 利的边缘和全身静脉排水的组合在预测外腹膜隔离 (ELS) 中非常准确.
- 这些成像发现可以显著帮助手术规划,并改善BPS手术前的患者咨询.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy
149
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Pneumothorax-II
107
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.
