Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

15
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 III: Interprofessional Care

12
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Pulmonary Embolism I: Introduction

14
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 III: Nursing Management

17
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...

Summary

Mechanical thrombectomy is effective for stroke, but the best device is unknown. Current evidence does not show the combined stent retriever and aspiration technique is superior to stent retrievers alone for patient outcomes.

Area of Science:

  • Neurology
  • Interventional Neuroradiology
  • Medical Devices

Context:

  • Mechanical thrombectomy is a key treatment for acute ischemic stroke.
  • Numerous devices and techniques exist, creating a need for comparative efficacy data.
  • The combined stent retriever and aspiration catheter technique has gained recent popularity.

Purpose:

  • To review the landscape of thrombectomy devices and techniques.
  • To evaluate the current evidence comparing different thrombectomy strategies.
  • To determine if the combined technique offers superior patient outcomes.

Summary:

  • Randomized trials confirm thrombectomy's efficacy in stroke treatment.
  • While various devices and techniques are available, optimal selection remains unproven.

  • No current evidence supports the superiority of combined stent retriever and aspiration techniques over stent retrievers alone in improving patient outcomes.

    • Impact:

    • Highlights the need for further research into optimal thrombectomy device selection.
    • Informs clinical decision-making regarding stroke treatment strategies.
    • Emphasizes the importance of evidence-based practice in interventional neurology.
