Trachea01:22

Trachea

6.2K
The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of...

Chronic Obstructive Pulmonary Disease II: Emphysema

155
Emphysema, a major phenotype of chronic obstructive pulmonary disease (COPD), is characterized by irreversible destruction of alveolar walls and permanent enlargement of distal airspaces. Unlike chronic bronchitis, which primarily affects the airways, emphysema predominantly involves the lung parenchyma, where structural damage leads to airflow limitation.PathophysiologyIt most commonly results from prolonged exposure to cigarette smoke and other toxic gases, particularly cigarette smoke.

Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features

77
Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...

Breathing01:05

Breathing

50.7K
The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

5.5K
In terms of human respiration, the act of expelling air, known as exhalation (or expiration), operates on the principle of pressure gradients. During expiration, the pressure within the lungs exceeds that of the surrounding atmosphere. Under normal conditions, quiet breathing involves passive exhalation and is free of muscular contractions. This is because the exhalation process is driven by the natural elastic recoil of the lungs and chest wall, both of which have an inherent tendency to...

The Bronchial Tree01:23

The Bronchial Tree

8.4K
The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

Area of Science:

  • Pulmonology
  • Thoracic Surgery
  • Medical Imaging

Background:

  • Tracheomalacia involves excessive trachea collapsibility, particularly during exhalation.
  • Congenital forms often cause severe symptoms, while milder cases may appear post-neonatally.
  • Adult tracheomalacia is frequently linked to chronic obstructive pulmonary disease.

Purpose of the Study:

  • To review current diagnostic and therapeutic strategies for tracheomalacia.
  • To evaluate the efficacy and safety of various treatment options.

Main Methods:

  • Review of existing literature on tracheomalacia diagnosis and management.
  • Analysis of noninvasive diagnostic tools like dynamic airway CT.
  • Assessment of surgical interventions including bronchoscopy, stent insertion, lateropexia, tracheal resection, and tracheoplasty.

Main Results:

  • Functional bronchoscopy lacks standardization.
  • Dynamic airway CT shows promise for noninvasive diagnosis.
  • Bronchoscopy with stent insertion improves outcomes but carries high complication risks.
  • Surgical options include lateropexia, tracheal resection, and external stabilization.
  • Tracheoplasty is effective for selected adult cases.
  • Aortopexy is the most frequent pediatric surgical procedure.

Conclusions:

  • Tracheomalacia diagnosis and treatment require tailored approaches.
  • Dynamic airway CT is a valuable noninvasive diagnostic tool.
  • Tracheoplasty represents an optimal surgical choice for specific adult tracheomalacia patients.
  • Aortopexy remains the standard surgical treatment for pediatric cases.
