Summary
The Spider FX™ filter embolic protection device (FEPD) is safe and effective for capturing debris during femoropopliteal artery interventions. However, a small risk of peripheral embolization persists despite its use.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Medical Device Technology
Background:
- Endovascular interventions for femoropopliteal artery disease carry a risk of embolic events.
- Filter embolic protection devices (FEPDs) are designed to mitigate this risk by capturing embolic debris.
- The Spider FX™ is one such device used in these procedures.
Purpose of the Study:
- To evaluate the safety and efficacy of the Spider FX™ FEPD.
- To assess the rate of filter macroembolization (FME) and distal embolization.
- To identify risk factors associated with FME.
Main Methods:
- Retrospective analysis of 244 femoropopliteal endovascular interventions using the Spider FX™ FEPD (2008-2016).
- Assessment of clinical and angiographic data, FME, device complications, and early outcomes.
- Multivariate analysis to determine risk factors for FME.
Main Results:
- FEPD placement and retrieval were highly successful.
- The overall rate of filter macroembolization (FME) was 37.3%.
- Distal embolization occurred in 4.1% of cases, with a higher incidence in those with FME.
Conclusions:
- The Spider FX™ FEPD demonstrates safety and effectiveness in capturing embolic debris during femoropopliteal interventions.
- Risk factors for FME include total occlusion, long lesions, visible thrombus, and diabetes.
- A residual risk of peripheral embolization necessitates continued vigilance.

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 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...

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...

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
