Insights

This study found that 76.9% of inferior vena cava filters (IVCFs) were successfully retrieved, with an adjusted rate of 94.15%. Filter tilting was a rare cause of retrieval failure, highlighting clinician control over the IVCF removal process.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Cardiology

Background:

  • Systemic anticoagulation is standard for venous thromboembolic disease.
  • Inferior vena cava filters (IVCFs) are used when anticoagulation is contraindicated or fails.
  • Rising IVCF complications necessitate timely retrieval when no longer indicated.

Purpose of the Study:

  • To evaluate the IVCF retrieval rate in a Spanish registry.
  • To analyze causes of failed retrieval and associated complications.
  • To assess 12-month outcomes following IVCF implantation and retrieval.

Main Methods:

  • Retrospective analysis of 356 IVCF implantations in 355 patients.
  • Data collection on filter types, retrieval success, and reasons for non-retrieval.
  • Assessment of procedure-related complications and 12-month patient outcomes.

Main Results:

  • A global IVCF retrieval rate of 76.9% (274/356) was achieved.
  • Reasons for non-retrieval included ongoing need for filtration (11.5%), patient death (6.7%), and filter embedding/tilting (4.7%).
  • No major complications were reported during retrieval procedures.

Conclusions:

  • The adjusted IVCF retrieval rate was high at 94.15% with no major complications.
  • Filter tilting was associated with <5% of retrieval failures.
  • The study suggests clinician control over IVCF retrieval procedures.

Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in...

Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

Extracorporeal Removal of Drugs: Hemoperfusion and Hemofiltration

Hemoperfusion and hemofiltration are critical techniques in medical treatments to eliminate accumulated drugs, metabolites, and electrolytes from the bloodstream. These methods are particularly vital in cases of accidental poisoning and drug overdose.Hemoperfusion involves passing blood through an adsorbent material to remove unwanted substances. The main adsorbents used in hemoperfusion include activated charcoal and Amberlite resins. Activated charcoal can adsorb both polar and nonpolar...

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...

Hemodialysis II: Procedure and Complications

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

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...
