Summary
The Celect and Günther Tulip Vena Cava Filters demonstrated safety and effectiveness in preventing pulmonary embolism (PE) over 2 years. This study supports their use in patients requiring inferior vena cava (IVC) filter placement.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Cardiology
Background:
- Pulmonary embolism (PE) remains a significant cause of morbidity and mortality.
- Inferior vena cava (IVC) filters are used to prevent PE in high-risk patients.
- Continued evaluation of IVC filter safety and effectiveness is crucial.
Purpose of the Study:
- To report 2-year outcomes of the Celect and Günther Tulip IVC filters.
- To assess the safety and effectiveness of these filters in a prospective, multicenter study.
- To evaluate filter placement success, PE prevention, and adverse events.
Main Methods:
- A prospective, multicenter, single-arm study (CIVC) enrolled 473 patients.
- Patients received either Celect or Günther Tulip IVC filters for PE prevention.
- Follow-up extended to 2 years, assessing technical success, symptomatic PE, and major adverse events.
Main Results:
- Technical placement success rate was 97.8%.
- The primary safety rate was 86.7% in post hoc analysis (P = .001).
- Successful filter retrieval occurred in 94.9% of cases, with minimal device-related complications.
Conclusions:
- The Celect and Günther Tulip IVC filters are safe and effective for PE prevention.
- The study supports the long-term use of these devices in appropriate patient populations.
- Further research may focus on optimizing patient selection and long-term outcomes.

01:26Varicose Veins II: Diagnostic Studies and Interprofessional Care
Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...
01:20Venous 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...
01:29Venous 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...
01:29Pulmonary 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...
01:24Hemodialysis 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,...
