    Insights

    Cava filters (CF) effectively prevent pulmonary thromboembolism (PTE) in patients with deep vein thrombosis of the inferior vena cava (VCI). Recurrence of PTE was not observed, with VCI thrombosis occurring in only 3.2% of cases after CF implantation.

    Area of Science:

    • Vascular Surgery
    • Interventional Radiology
    • Thrombosis Management

    Context:

    • Deep vein thrombosis (DVT) of the inferior vena cava (VCI) poses a significant risk of pulmonary thromboembolism (PTE).
    • Inferior vena cava filters (IVCFs) are utilized for PTE prophylaxis in select patient populations.
    • This study analyzes the outcomes of IVCF implantation in patients with VCI thrombosis.

    Purpose:

    • To evaluate the efficacy and safety of vena cava filters (CF) in preventing pulmonary thromboembolism (PTE) in patients with deep vein thrombosis (DVT) of the inferior vena cava (VCI).
    • To assess the recurrence rate of PTE and the incidence of VCI thrombosis following CF implantation.

    Summary:

    • A retrospective analysis of 148 patients with VCI deep vein thrombosis was conducted.
    • Fifty patients received vena cava filters (CF), including temporary CF-thrombextractors and permanent CF 'Osot'.
    • No cases of recurrent PTE were observed, and VCI thrombosis occurred in 3.2% of patients post-implantation.

    Impact:

    • Vena cava filters demonstrate a high efficacy in preventing PTE in patients with VCI thrombosis.
    • The use of CFs is associated with a low incidence of VCI thrombosis, suggesting a favorable risk-benefit profile.
    • These findings support the role of IVCFs as a crucial intervention for PTE prophylaxis in high-risk patients.

    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 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...

    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...

    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...

    Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
    Airborne precautions:
    Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
