Abstract
Objective: To indentify factors influencing clinical outcomes of infrapopliteal percutaneous transluminal angioplasty (PTA). Subject and method: A retrospective and cross-sectional study was conductued on 91 infrapopliteal lesions of 85 patients suffering from lower extremity arterial disease (LEAD) treated in the Dept. of Cardiovascular Diagnosis and Intervention, the 108 Military Central Hospital, from May 2011 to June 2016. Result: The study showed that clinical stage of LEAD was more serious associated with hemodynamic success and higher 12 month restenosis rate (p<0.05). Infrapopliteal arterial lesion classification was more serious associated with lower 1 month wound healing rate (p<0.05) and higher 12 month restenosis (p<0.05). Patients with multi level arterial lesion had higher hemodynamic success and 12 month reintervention rate when compared to isolate infrapopliteal (85.7%, 22.2%, 28.3% in multi level group, 60%, 2.9%, 6.1% in isolate infrapopliteal group, respectively, p<0.05). The wound healing in direct angiosome group was significantly shorter than indirect group (2.6 ± 1.7 months and 4.4 ± 1.7 months, respectively, p<0.05). Conclusion: Clinical stage of LEAD, infrapopliteal arterial lesion classification (TASC 2015), multi level arterial lesion and infrapopliteal revascularization based on angiosome are factors influencing clinical outcome of infrapopliteal PTA.
