Pulmonary Embolism I: Introduction01:29

Pulmonary Embolism I: Introduction

386
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Pneumothorax-I01:26

Pneumothorax-I

935
A pneumothorax is a condition where air builds up in the space between the lung and the chest wall, causing the lung to collapse. This condition arises when air enters the space between the parietal and visceral pleura, disrupting the negative pressure essential for lung inflation. This can lead to a partial or complete collapse of the lung.
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.

Pulmonary Cycle: Exhalation01:17

Pulmonary Cycle: Exhalation

2.8K
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...

Pleura of the Lungs01:13

Pleura of the Lungs

5.5K
The lungs are nestled in a cavity, shielded by the pleura. The pleura, a form of serous membrane, wraps around each lung. This membrane arrangement consists of two layers: the visceral and parietal pleurae. The visceral pleura lines the surface of the lungIn contrast, the parietal pleura is the outer layer and contacts to the thoracic wall, the mediastinum, and the diaphragm. The hilum is the point of connection between the visceral and parietal layers. The space between the parietal and...

Pulmonary Ventilation: Inhalation01:24

Pulmonary Ventilation: Inhalation

6.8K
Pulmonary ventilation is a vital process that ensures the exchange of oxygen and carbon dioxide in the lungs. It refers to the movement of air into and out of the lungs, enabling the body to obtain oxygen and remove waste carbon dioxide. In this article, we will explore the intricacies of pulmonary ventilation, including its underlying principles, mechanisms, and the interplay of pressures within the respiratory system.
Boyle's law becomes particularly pertinent when examining respiratory...

Pulmonary Tuberculosis II01:28

Pulmonary Tuberculosis II

1.2K
Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Summary
This summary is machine-generated.

Pulmonary sequestration, a rare lung condition, was identified in a patient with persistent left lower lobe consolidation. Surgical removal via thoracoscopic surgery was recommended for this rare congenital anomaly.

Area of Science:

  • Pulmonology
  • Thoracic Surgery
  • Radiology

Background:

  • Pulmonary sequestration is a rare congenital lung malformation.
  • Early diagnosis and treatment are crucial for managing complications.

Observation:

  • A 45-year-old female presented with persistent left lower lobe consolidation on CT scan.
  • Initial antibiotic treatment failed to resolve the consolidation.

Findings:

  • Repeat CT scan with contrast confirmed the consolidation as pulmonary sequestration.
  • This rare condition involves lung tissue with abnormal blood supply.

Implications:

  • Accurate diagnosis of pulmonary sequestration is vital for appropriate management.
  • Video-assisted thoracoscopic surgery offers a minimally invasive approach for resection.
