A 5.5 years observational follow-up study of patients with critical limb ischaemia treated efficiently by endovascular approach

Objectives – The aim of this study was to describe our experience with endovascular treatment in critical limb ischaemia and to bring new follow-up data about these patients with initial successfully revascularization. Methods – A retrospective study of 181 patients with critical limb ischaemia, with successful endovascular treatment in our institution was performed. We followed death, reintervention and amputation rates during a mean period of 55.1 ± 8.2 months. Results – The mean age of the patients was 65.2±11.6 years. Of these patients, 66.3% were males, 38.1% diabetics, 51.4% active smokers, 21% with chronic kidney disease, 32.6% with other clinical forms of peripheral artery diseases. The final treatment was stenting in 31.5% of cases and balloon angioplasty alone in the rest of the cases. Treated arteries were in the femoral-popliteal segment – 55.6%, aorto-iliac segment – 31.4% and infrapopliteal segment – 13%. 27.6% of the patients underwent procedures on more than one arterial segment. During follow up 11 deaths occurred (6.1%), 27 patients (14.9%) underwent reinterventions for revascularization (endovascular or surgical) and 31 patients (17.1%) suffered further amputations. Conclusions – Despite a certain rate of death, amputation and reintervention, our results suggest that endovascular approach in critical limb ischaemia can be an effi cient and feasible treatment option if its results are optimal at the time of implementation.
