Retrievable vena cava filters: a clinical review

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Cardiology

Background:

• Venous thromboembolism (VTE), encompassing deep vein thrombosis and pulmonary embolism (PE), is a significant cause of illness and death.
• Standard treatment involves parenteral anticoagulation followed by oral vitamin K antagonists.
• Inferior vena cava (IVC) filters are used when anticoagulation is contraindicated, causes bleeding, or is ineffective, to prevent life-threatening PE.

Purpose of the Study:

• To review the current literature on retrievable vena cava filters.
• To discuss the efficacy and safety evidence for retrievable IVC filters.
• To outline appropriate clinical indications for their use.

Main Methods:

• Comprehensive literature review of studies on retrievable vena cava filters.
• Analysis of current evidence regarding filter efficacy and safety profiles.
• Evaluation of clinical practice guidelines and indications for filter implantation and retrieval.

Main Results:

• Permanent IVC filters are widely used but associated with long-term complications.
• Retrievable IVC filters provide an alternative that can be removed once the risk of PE has diminished.
• Evidence supports the efficacy and safety of retrievable filters in selected patient populations.

Conclusions:

• Retrievable vena cava filters are a valuable option for VTE management, offering a balance between PE prevention and reduced long-term risks.
• Careful patient selection and adherence to indications are crucial for optimal outcomes with retrievable filters.
• Further research may refine indications and long-term outcomes for retrievable IVC filter use.
