Pulmonary Embolism I: Introduction01:29

Pulmonary Embolism I: Introduction

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...
Pulmonary Embolism I: Introduction01:19

Pulmonary Embolism I: Introduction

A blood clot, or thrombus, is a semi-solid mass composed of fibrin, platelets, and red blood cells. When it forms within a vessel, it can obstruct blood flow, known as thrombosis. If part of the clot detaches, it becomes an embolus that can travel and block distant vessels. When this occurs in the pulmonary arteries, it causes a condition known as pulmonary embolism (PE).Origin and ImpactMost often, the embolus originates from a thrombus in the deep veins of the lower limbs, a condition called...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
Atelectasis II: Pathophysiology01:10

Atelectasis II: Pathophysiology

Atelectasis develops when alveoli lose their air and collapse inward. Because lung tissue is naturally elastic, these air sacs shrink rather than remaining open. Collapsed alveoli are no longer ventilated, reducing their role in gas exchange. Blood flow may continue in these regions, creating a ventilation–perfusion mismatch. Clinical findings include decreased breath sounds, dullness to percussion, reduced chest expansion, and decreased tactile fremitus as sound transmission through collapsed...

Chronic Obstructive Pulmonary Disease-II: Pathophysiology

Chronic Obstructive Pulmonary Disease (COPD) pathophysiology is intricate and multifaceted, involving a complex interplay of physiological processes. Understanding these mechanisms is crucial for effectively managing and treating COPD. Here is an in-depth look at the critical elements in the pathophysiology of COPD:

Summary

Takayasu arteritis can cause isolated pulmonary artery occlusion, presenting diagnostic challenges. Early recognition is crucial for managing this rare condition, even with normal systemic arteries.

Area of Science:

  • Cardiology
  • Vascular Medicine
  • Rheumatology

Background:

  • Takayasu arteritis (TA) is a rare inflammatory condition affecting large arteries.
  • It can uncommonly manifest as isolated bilateral pulmonary artery occlusion.
  • Distinguishing TA from other causes of pulmonary artery occlusion can be challenging.

Observation:

  • A 19-year-old female presented with dyspnea and hemoptysis over two years.
  • Investigations revealed total occlusion of the right pulmonary artery and partial left lower lobe artery occlusion.
  • Initial corticosteroid treatment for suspected Takayasu arteritis showed no clinical improvement.

Findings:

  • Pulmonary angiography confirmed bilateral pulmonary artery occlusion.
  • Aortography was normal, complicating the diagnosis of Takayasu arteritis.
  • The patient's condition worsened, requiring oxygen support.

Implications:

  • Isolated pulmonary artery involvement in Takayasu arteritis poses diagnostic difficulties.
  • Clinical presentation (young age) and angiographic findings suggested Takayasu arteritis despite normal systemic arteries.
  • This case highlights the importance of considering Takayasu arteritis in young patients with unexplained pulmonary artery occlusion.
