The new titanium Greenfield vena cava filter: initial experience and review

Area of Science:

• Vascular Surgery
• Interventional Radiology

Background:

• Pulmonary embolism (PE) prevention is crucial, with vena cava filters being a key therapeutic option.
• The development of the 12-French modified titanium Greenfield filter (TGF) enables percutaneous insertion and aims for lower complication rates.

Observation:

• This study reports the initial experience with percutaneous insertion of the 12-French TGF in 6 patients with extensive deep venous thrombosis (DVT) and contraindications to anticoagulation.
• The inferior vena cava (IVC) filters were inserted via the internal jugular vein without difficulty, bruising, hematoma, or bleeding complications.
• Filter deployment and leg opening were successful without cross-snaring, confirmed by imaging, with minor asymmetry noted but no significant angulation or migration.

Findings:

• Percutaneous insertion of the 12-French TGF was safely achieved in all 6 patients.
• No procedural complications were observed in this small patient cohort.
• The titanium Greenfield filter demonstrated secure placement without immediate post-procedure migration.

Implications:

• The 12-French TGF offers a safe and effective option for percutaneous vena cava filter placement.
• Titanium construction maintains clinical effectiveness while improving ease of insertion and patient comfort.
• This approach is particularly valuable for patients with DVT and contraindications to anticoagulation therapy.
