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 III: Interprofessional Care

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 III: Nursing Management

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...
Pulmonary Embolism I: Introduction01:19

Pulmonary Embolism I: Introduction

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 I: Introduction

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

Air embolism during cardiac procedures is rare but serious. A case report shows the AngioJet catheter can effectively aspirate coronary air emboli, restoring blood flow.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Medical Devices

Background:

  • Air embolism is a rare complication during cardiac catheterization and percutaneous coronary intervention.
  • Current treatments for air emboli include manual aspiration or saline injection, with limited efficacy.
  • The AngioJet device uses rheolytic thrombectomy for thrombus removal via high-velocity saline jets.

Observation:

  • A massive air embolus occurred in the right coronary artery after using an AngioJet catheter in a patient with a thrombus-laden artery.
  • The AngioJet catheter was subsequently used to successfully aspirate the air embolus.
  • This is the first reported case of air embolism associated with AngioJet activation.

Findings:

  • The AngioJet catheter, designed for thrombus removal, demonstrated efficacy in aspirating a massive coronary air embolus.

Published on: September 17, 2014

  • Successful aspiration of the air embolus led to the restoration of coronary blood flow.
  • The use of a nonocclusive guiding catheter with side holes may prevent air entrainment during AngioJet activation.

    • Implications:

    • The AngioJet catheter presents a potential new treatment option for managing coronary air embolism.
    • This case highlights a novel complication associated with rheolytic thrombectomy devices.
    • Further investigation into preventative strategies and therapeutic applications of the AngioJet for air embolism is warranted.
