Over the last two decades, surgeons have increasingly embraced endovascular techniques as an alternative mode of treatment for symptomatic infrainguinal occlusive disease. Duplex scan has become not only a screening test but also provided the definitive diagnosis for a number of conditions. This study has two purposes: to describe our experience of duplex-guided balloon angioplasty (DGBA) of superficial femoral artery lesions, and to analyze and compare our results with those obtained from other similar studies.
