FEMOROPOPLITEAL ANGIOPLASTY VS OPEN SURGERY FOR CHRONIC LIMB-THREATENING ISCHEMIA

Abstract

The aim: To compare the results of femoro-popliteal PTA vs open surgery in chronic limb-threatening ischemia (CLTI) and analyze clinical efficacy long-term results. Materials and methods: Between 2018 – 2019, 145 patients with CLTI who underwent femoro-popliteal arterial segment steno-occlusive lesions (SOL) unilateral revascularization. Open surgery were performed for – 48 (33, 1℅), percutaneous transluminal angioplasty (PTA) for – 73 (50.3%), and were treated with hybrid surgical interventions for – 24 (16.6%). Results: During the analysis, no statistically significant difference was found among the three groups patients indicators. According to the diabetes patients indicator, the differences among the groups are statistically significant (p<0.001), diabetes was present in only 16.7% of open surgical intervention group patients, 45.8% of PTA group patients, 54.8% of the hybrid surgery group patients. In the overall comparison 2-year limb preservation after open surgery 93.8%, after PTA 91.7%, and after hybrid surgery 91.6%; amputations: open surgery – 6.2% PTA- 8.2 %, hybrid surgery -8.3%; exemption from surgical re-intervention: open surgery - 68.7%, PTA- 58.9%, hybrid surgery – 75%. There were no differences in limb preservation and amputation between open surgery, hybrid intervention, and PTA. A difference was found only in reintervention tactic among the open surgery and PTA groups as opposed to the hybrid surgery. Сonclusions: Limb salvage and CLTI patients survival after open surgery and PTA who were not performed major amputation in 2 years term after revascularization were comparable regardless of treatment method.
