  1. Atelectasis นพ. ชัชชัย หอมเกตุ

  2. Atelectasis • สภาพที่ปอดส่วนใดส่วนหนึ่ง หรือทั้งข้างแฟบลง (volume loss) เนื่องจากลมภายในน้อยลงหรือไม่มีเลย

  3. Atelectasis • Obstructive : endobronchial, external • compression • 2. Passive : pneumothorax, hydrothorax • Compressive : space taking lesion (mass, bulla) • Adhesive : surfactant deficiency (RDS) • Cicatrization : fibrosis, scar

  4. Atelectasis • Increased density • Volume loss - Deviation or displacement of fissure - Clouding of bronchus and vessels - Hilar displacement - Elevation of hemidiaphragm - Displacement of mediastinum - Decreased intercostal space - Compensatory overinflation - Tenting or beak diaphragm

  5. Atelectasis • Direct signs - Increased density - Displacement of fissure - Clouding of bronchus and vessels

  6. RUL atelectasis

  7. RUL Atelectasis

  8. RUL Atelectasis

  9. RML atelectasis

  10. RML Atelectasis

  11. LUL atelectasis

  12. LUL atelectasis

  13. LUFTSICHEL SIGN

  14. RLL atlectasis

  15. RLL atelectasis

  16. Discoid Atelectasis

  17. Total Left Lung Atelectasis

  18. GOLDEN S SIGN • Peripheral lung collapse & central portion is prevented by presence of the mass • Relevant fissures are concave peripherally but convex centrally (resemble S or reverse S) • Importance – realize presence of central obstruction ex. bronchogenic carcinoma • Initially described for RUL atelectasis, in fact applicable for any lobes
