Treatment for femoral pseudoaneurysms

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Medical Device Technology

Background:

• Femoral pseudoaneurysms occur in up to 8% of vascular interventional procedures.
• While small pseudoaneurysms may resolve spontaneously, definitive treatment is often necessary.
• Traditional surgical treatment carries risks, especially for patients with severe cardiovascular disease.

Purpose of the Study:

• To evaluate the effectiveness of various treatments for femoral pseudoaneurysms following endovascular procedures.
• To specifically assess less invasive options like compression and percutaneous thrombin injection.

Main Methods:

• A systematic review of randomized controlled trials (RCTs) comparing treatments for femoral pseudoaneurysms.
• Included studies compared manual compression vs. ultrasound-guided compression, mechanical device vs. blind application, and ultrasound-guided compression vs. percutaneous thrombin injection.
• Data extraction was performed independently by two authors.

Main Results:

• Compression (manual or mechanical) effectively achieved pseudoaneurysm thrombosis; ultrasound guidance did not improve outcomes.
• Percutaneous thrombin injection demonstrated higher efficacy than single-session ultrasound-guided compression in individual RCTs, though pooled data lacked statistical significance.
• No significant difference in hospital stay was observed; deep vein thrombosis was the only reported complication.

Conclusions:

• Limited evidence supports percutaneous thrombin injection as an effective treatment for femoral pseudoaneurysms.
• A pragmatic approach suggests using compression (blind or ultrasound-guided) as initial therapy, with thrombin injection reserved for refractory cases.
