まとめ
肺移植後の胞流出は死亡リスクを増加させる. 早期の出血は肺アロ移植機能障害と関連し,遅い出血は生存に重大な脅威をもたらす.
科学分野:
- 肺医学
- 移植免疫学
- 胸部 外科
背景:
- 不明な病因の胞流出は,肺アロ移植を受けた患者の悪い結果と関連しています.
- 肺移植後の胞流出 (LTX) の危険因子の特定は,アロ移植機能と生存を理解するために重要である.
- 予後のために,早期と後期の膜流出を区別することが重要です.
研究 の 目的:
- 肺移植 (LTX) の後の胞流出の新たな危険因子を特定する.
- 胸腔流出とアロ移植機能と生存の関連性を調査する.
- 早期の肺流出と遅い肺流出の影響を区別する.
主な方法:
- LMUクリニクム・ミュンヘン (2013年−2018年) で移植された肺アロ移植受容者の遡及分析.
- 胸腔凝縮を要するすべての胸腔噴出および関連する臨床データの分析を含む.
- 369人の受診者における426件の膜流出の分析で,追跡期間の中央値は6. 9年であった.
主要な成果:
- 早期 (< 90日) と遅い (> 90日) プレウラ出血は死亡率の増加と関連していました.
- 後期性流は高い死亡リスクを示した (HR 4. 0).
- 早期の膜流出は,基礎肺アロ移植機能不全 (BLAD),閉塞性疾患,ドナー臓器のサイズ不足,およびクラッシュシェル胸切除と相関する.
結論:
- LTX後の胞流出は死亡率の増加の重要な指標です.
- 早期の胞流出はBLADと関連しており,アロ移植機能障害との関連を示唆しています.
- 胸腔流出とBLADと死亡率を結びつけるメカニズムは,さらなる調査が必要である.

Endoscopic Studies II: Thoracocentesis
496
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Pleural Effusion I: Introduction
1.8K
Pleural effusion is an abnormal fluid accumulation in the pleural cavity, a narrow space between the lungs and the chest wall. It is not a disease per se but rather a symptom or indication of an underlying disease. In normal circumstances, this space contains a small amount of fluid (5 to 15 mL), a lubricant facilitating the non-frictional movement of the pleural surfaces.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

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...
