This study aimed to evaluate midterm outcomes of conventional percutaneous transluminal angioplasty (PTA) in the treatment of femoropopliteal steno-obstructive disease and assess the effect of risk factors on patency rates.
One hundred consecutive patients with femoropopliteal steno-obstructive disease underwent PTA, for a total of 104 procedures. Presence of cardiovascular risk factors, TransAtlantic Inter-Society Consensus (TASC) classification, runoff status, pre-and postprocedural clinical data and procedure outcome were recorded. Follow-up consisted of clinical assessment and colour Doppler ultrasonography at 1, 6 and 12 months.
Technical success was 96% (96/100). Seven lesions required stent placement. Primary and secondary patency rates were 82.7% and 88.8% at 6 months and 74.3% and 81.5% at 12 months, respectively. Primary patency rates at 12 months were significantly higher for TASC A-B-C lesions than for TASC D lesions (p < 0.05). Primary patency rates at 12 months were 61.6% and 78.8% (p<0.05) for poor or adequate runoff status, respectively.
Conventional PTA is a minimally invasive alternative to bypass surgery for treating TASC A-C atherosclerotic lesions in the presence of adequate runoff.
