RESUMO
Abstract: This study aims at determining the effectiveness of infrapopliteal [IP] percutaneous transluminal angioplasty [PTA] techniques for treatment of infrapopliteal Peripheral arterial disease [PAD]
Methods: This study is a case series, combined prospective and retrospective, including 108 limbs in 104 patients with infrapopliteal PAD of Fontaine IIb, III and IV stages/ Rutherford categories 3, 4, 5 and 6. Patients underwent PTA using balloon dilatation in 73.1%, bare metal stents in 17.6%, Drug eluting balloon in 7.4%, and Drug eluting stent in 0.9% between February 2009 and January 2015
Results: Technical success was 94.2%. Primary patency at 3, 6, 12, 24 months are 92.9%, 79.3%, 69.5%, and 58.3% respectively, and was adversely affected by smoking [p=0.005]. Limb salvage at 1 year was 92.6%, and was adversely affected by smoking [p=0,027], diabetes [p=0.009], and Updated TASC II [p=0.023]
Conclusion: Infrapopliteal PTA is a safe, successful, and effective technique for treatment of critical limb ischemia, with an excellent technical success rate, good limb salvage rate, and a low pen-procedural morbidity and mortality
