Pneumothorax-II01:27

Pneumothorax-II

119
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Radiological Investigation III: Pulmonary Angiogram and PET Scan

82
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Pneumothorax-I

168
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.

Summary

A normal D-dimer test does not always rule out pulmonary embolism (PE). This case highlights the need for clinical judgment and imaging in diagnosing PE, even with negative D-dimer results.

Area of Science:

  • Medicine
  • Cardiology
  • Pulmonology

Background:

  • Pulmonary embolism (PE) is a life-threatening condition caused by lung circulation obstruction.

  • The D-dimer test is commonly used to exclude PE, but its accuracy can be limited.
  • Acromegaly is a potential risk factor for thromboembolic events.
