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...

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...

Venous Thrombosis I: Introduction

177
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Pulmonary Embolism III: Nursing Management

205
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...

Extrinsic and Intrinsic Pathways of Hemostasis01:20

Extrinsic and Intrinsic Pathways of Hemostasis

11.3K
Blood clotting or coagulation involves extrinsic and intrinsic pathways, which ultimately merge into the common pathway, forming a fibrin clot.
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...

Pulmonary Hypertension: Classification and Pathogenesis01:30

Pulmonary Hypertension: Classification and Pathogenesis

473
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Summary
This summary is machine-generated.

Hydatid pulmonary embolism (HPE) is a rare nonthrombotic embolism. Surgical treatment, often involving embolectomy, is effective for hydatid material in pulmonary arteries, with a low mortality rate.

Area of Science:

  • Cardiology
  • Pulmonology
  • Parasitology

Background:

  • Hydatid pulmonary embolism (HPE) is an uncommon cause of nonthrombotic embolism, particularly relevant in endemic regions.
  • Prompt recognition is crucial for effective management.

Purpose of the Study:

  • To assess the radioclinical characteristics and surgical treatment outcomes for patients with hydatid material in the pulmonary arterial circulation.
  • To highlight the diagnostic and therapeutic approach for this rare condition.

Main Methods:

  • A retrospective review of 10 patients treated for HPE between 2000 and 2014.
  • Analysis of clinical presentation, diagnostic imaging (Computed Tomography Angiography - CTA), and surgical interventions (embolectomy).

Main Results:

  • The study included 10 patients (6 males, 4 females; average age 28 years).
  • CTA successfully visualized hydatid material in 9 cases. Surgical embolectomy under cardiopulmonary bypass was performed in 9 patients, often preceded by treatment of the primary hydatid cyst.
  • A single patient died postoperatively, indicating a high survival rate with surgical intervention.

Conclusions:

  • Endoluminal hydatid involvement of pulmonary arteries is exceptionally rare.
  • CTA is a valuable diagnostic tool for HPE.
  • Surgical treatment is the recommended approach when feasible, offering favorable outcomes.
