Vena cava filters in spinal cord injuries: evolving technology

Area of Science:

• Medical research
• Nephrology
• Trauma surgery

Background:

• Deep venous thrombosis (DVT) affects 60-100% of spinal cord injury (SCI) patients.
• Current guidelines recommend anticoagulation, compression devices, and stockings for venous thromboembolism (VTE) prophylaxis.
• Vena cava filters (VCFs) are reserved for secondary prophylaxis in specific SCI cases.

Purpose of the Study:

• To clarify the indications and use of vena cava filters (VCFs) in patients with spinal cord injury (SCI).
• To evaluate the safety and efficacy of VCFs for VTE prophylaxis in SCI.
• To discuss available retrievable VCF options.

Main Methods:

• Literature review of VCF use in trauma and SCI patients.

Main Results:

• Prophylactic VCF use is increasing in trauma patients, including those with SCI.
• Filter placement effectively prevents pulmonary emboli with a low complication rate.
• Indications include recurrent pulmonary embolism, contraindications to anticoagulation, and free-floating thrombus.

Conclusions:

• Retrievable VCFs are a safe and feasible option for secondary VTE prophylaxis in SCI patients.
• Defining objective criteria for temporary and permanent VCF placement is necessary.
