This study retrospectively evaluated the safety and efficacy of aspiration thrombectomy using a large-size catheter for acute lower extremity deep vein thrombosis (DVT).

Methods

All patients who underwent aspiration thrombectomy using 9F or 10F catheters for acute lower extremity DVT were included and analyzed. Aspiration thrombectomy was performed in all patients. Additional intravenous thrombolysis was performed in patients with residual thrombus, and stent placement was performed in patients with iliac vein compression syndrome.

Results

From October 2010 to September 2013, the study enrolled 68 patients (37 women, 31 men) with a mean age of 61.7 ± 7.8 years (range, 24-86 years). All patients presented with lower extremity swelling and pain, and the duration of symptoms ranged from 1 to 14 days. The DVTs involved popliteal-iliofemoral veins in 29 patients, iliofemoral veins in 31, and iliac veins in 8. Endovascular procedures were performed in all patients with a technical success rate of 100%. Aspiration alone was effective in 47 patients, and additional thrombolysis was required in the remaining 21. An additional stent was required in 32 patients. Significant improvement in presenting symptoms was achieved in all patients after the procedures, with a clinical success rate of 100%. There were no procedure-related or thrombolysis-related complications. The Villalta scores were <5 in 60 patients and from 5 to 9 in four patients. Primary and secondary patency rates were 89.1% (57 of 64) and 96.9% (62 of 64) at 1 year of follow-up.

Conclusions

Aspiration thrombectomy using a large-size catheter is safe and effective for acute lower extremity DVT.
