Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

180
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 I: Introduction

404
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

Carotid angioplasty and stenting (CAS) offers a new alternative to carotid endarterectomy (CEA). Advances in embolic protection devices aim to reduce stroke risk during CAS procedures.

Area of Science:

  • Interventional cardiology and neurology
  • Medical device technology
  • Cerebrovascular disease management

Background:

  • Carotid angioplasty and stenting (CAS) is emerging as a significant alternative to carotid endarterectomy (CEA).
  • Technological advancements in endoluminal equipment and cerebral embolic protection devices have driven this evolution.
  • These devices theoretically mitigate distal embolization, reducing the risk of cerebrovascular accidents.

Purpose of the Study:

  • To review the current landscape of mechanical cerebral embolic protection devices used in CAS.
  • To categorize these devices based on their mechanism of action.
  • To provide a framework for understanding their role in minimizing stroke risk during CAS.

Main Methods:

  • Literature review of embolic protection devices for carotid angioplasty and stenting.
