Insights

Inferior vena cava (IVC) filters are a safe and effective treatment for preventing pulmonary embolism (PE) when anticoagulation is not an option. This study shows IVC filter implantation has good long-term outcomes for patients with deep vein thrombosis (DVT) or PE.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Cardiology

Background:

  • Anticoagulation is standard for deep vein thrombosis (DVT) and pulmonary embolism (PE).
  • Inferior vena cava (IVC) filter placement is indicated when anticoagulation is contraindicated or ineffective.
  • IVC filters serve as a crucial intervention for preventing PE in select patient populations.

Purpose of the Study:

  • To evaluate the clinical experience and outcomes of inferior vena cava (IVC) filter implantation.
  • To assess the safety and efficacy of IVC filters in preventing PE.
  • To report on the long-term follow-up of patients undergoing IVC filter procedures.

Main Methods:

  • Retrospective review of medical records and operative protocols for patients who received IVC filters between 1993 and 2005.
  • Follow-up conducted via telephone, ambulatory consultation, or death certificates.
  • Analysis of implantation success, complications, and long-term outcomes.

Main Results:

  • 287 patients underwent IVC filter implantation, with indications including contraindication/complication of anticoagulation, prophylaxis, and massive PE.
  • All percutaneous devices were successfully inserted with no procedure-related morbidity or mortality.
  • Mean follow-up was 41.5 months, with a 5-year survival rate of 64.7%. Recurrent symptomatic PE occurred in 2.1% of patients.

Conclusions:

  • Inferior vena cava (IVC) filter implantation is a safe and effective procedure.
  • IVC filters provide a valuable short- and long-term measure for preventing PE.
  • The study demonstrates favorable outcomes and low complication rates associated with IVC filter use.

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...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Veins of the Abdomen and Pelvis

The human body is a complex system of interconnected parts, and the circulatory system plays a crucial role in maintaining overall health. One key component of this system is the inferior vena cava, a large vein responsible for returning blood from the abdominopelvic viscera and abdominal walls to the heart.
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...

Endocarditis IV: Nursing Management

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...

Hemodialysis I: Introduction

Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...
