Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

44
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...

Esophageal Varices-II: Clinical Features and Management

140
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol...

Pulmonary Embolism I: Introduction

46
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...

Summary
This summary is machine-generated.

Splenic artery embolisation (SAE) is effective for unstable trauma patients with splenic laceration, showing high splenic salvage and no increased mortality compared to splenectomy. This supports SAE as a primary treatment.

Area of Science:

  • Trauma Surgery
  • Interventional Radiology
  • Emergency Medicine

Background:

  • Splenic artery embolisation (SAE) is standard for stable blunt splenic trauma.
  • Current guidelines recommend splenectomy for unstable patients.
  • Limited data exist on SAE efficacy in hemodynamically unstable trauma patients.

Purpose of the Study:

  • To evaluate the efficacy of splenic artery embolisation (SAE) in preventing mortality in hemodynamically unstable patients with blunt splenic laceration.
  • To compare SAE with upfront splenectomy in this patient cohort.

Main Methods:

  • Retrospective case-control study over 13.5 years.
  • Identified patients with blunt splenic laceration undergoing SAE or splenectomy.
  • Compared hemodynamically unstable patients (shock index ≥ 1.0 or SBP < 90 mmHg) undergoing SAE versus splenectomy.

Main Results:

  • 126 unstable patients underwent SAE; 8 underwent upfront splenectomy.
  • SAE achieved 98% splenic salvage and 4% 30-day mortality.
  • No significant difference in 30-day mortality between SAE and splenectomy groups (p=0.34).

Conclusions:

  • Splenic artery embolisation is safe and effective for unstable blunt splenic trauma.
  • SAE demonstrates comparable mortality rates to upfront splenectomy in this group.
  • Supports SAE as a primary treatment standard for unstable splenic laceration.
