Pulmonary Embolism I: Introduction01:29

Pulmonary Embolism I: Introduction

1.5K
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: Introduction

39
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...

Pulmonary Embolism III: Nursing Management

756
A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

722
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...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

1.0K
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Area of Science:

  • Obstetrics and Gynecology
  • Cardiology
  • Radiology

Background:

  • Pulmonary embolism (PE) in pregnancy presents a significant mortality risk.
  • Symptoms of PE in pregnant individuals can mimic normal pregnancy, complicating diagnosis.
  • Timely assessment and investigation are crucial for pregnant patients presenting with possible PE.

Purpose of the Study:

  • To highlight the diagnostic challenges of PE in pregnancy.
  • To address the anxiety surrounding imaging risks for mother and fetus.
  • To emphasize the importance of shared decision-making in investigating PE during pregnancy.

Main Methods:

  • Review of current diagnostic approaches for PE in pregnant patients.
  • Discussion of risk-benefit analysis for imaging modalities.
  • Consideration of obstetric management and follow-up protocols.

Main Results:

  • Differentiating PE symptoms from normal pregnancy is challenging.
  • Imaging is frequently required, necessitating discussion of radiation risks.
  • Informed patient consent is vital for diagnostic procedures.

Conclusions:

  • Management of PE in pregnancy requires a multidisciplinary approach.
  • Obstetric considerations are important at delivery.
  • Specialist follow-up is recommended for pregnant women diagnosed with PE.
