Trachea01:22

Trachea

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 the...
The Bronchial Tree01:23

The Bronchial Tree

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...
Anatomy of Respiratory System II: Lower Respiratory Tract01:31

Anatomy of Respiratory System II: Lower Respiratory Tract

The lower respiratory tract is anatomically composed of several vital structures, including the larynx, trachea, bronchial tree, alveoli, lungs, and pleurae. Each component has a specific function, and all are intricately connected to ensure efficient respiration.
The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...
Tracheostomy: Procedure and Tubes01:28

Tracheostomy: Procedure and Tubes

A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...
Endotracheal Intubation I: Procedure01:15

Endotracheal Intubation I: Procedure

Endotracheal or ET intubation is a critical medical procedure used to secure a patient's airway, often in acute respiratory distress, apnea, upper airway obstruction, ineffective clearance of secretions, high risk for aspiration, or during general anesthesia.
The ET tube comprises various components, including a standard adaptor to attach a bag-valve-mask (BVM) or ventilator, a cuff, a pilot balloon, and radiopaque markings along its length to measure the insertion distance. The tube sizes...
Cystic Fibrosis: Pathogenesis01:23

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...

Area of Science:

  • Thoracic surgery
  • Pulmonology
  • Medical imaging

Background:

  • Bronchogenic cysts are congenital anomalies typically found in the lungs or mediastinum.
  • Intratracheal or subcarinal extension of mediastinal bronchogenic cysts is exceptionally rare.
  • Symptoms like dry cough and stridor can indicate airway obstruction.

Purpose of the Study:

  • To report a rare case of a mediastinal bronchogenic cyst.
  • To highlight the diagnostic and surgical management of intratracheal cysts.
  • To emphasize the importance of considering rare differential diagnoses for airway lesions.

Main Methods:

  • Case presentation of a 68-year-old woman with respiratory symptoms.
  • Computed tomography (CT) of the chest for lesion characterization.
  • Surgical resection of the mediastinal cyst.

Main Results:

  • CT revealed a cystic, polypoid lesion protruding into the trachea from the subcarina.
  • The cyst wall was found to penetrate the tracheal wall upon resection.
  • Successful surgical removal of the lesion.

Conclusions:

  • Mediastinal bronchogenic cysts can present rarely with intratracheal extension.
  • CT imaging is crucial for diagnosing such rare airway lesions.
  • Surgical resection is an effective treatment for symptomatic intratracheal bronchogenic cysts.
