Autonomy Following Revascularisation in 80-year-old Patients with Critical Limb Ischaemia

Objectives We wanted to compare autonomy recovery after open and endovascular infrainguinal surgery for critical limb ischaemia (CLI) in octogenarians. Materials and methods We performed a retrospective analysis of 167 consecutive CLI octogenarians who underwent infrainguinal open surgery (OS) or endovascular surgery (ES) between 2003 and 2008. OS and ES groups were compared in terms of autonomy level (Parker score), survival, limb salvage and patency rates. Results Preoperative autonomy level was similar in both groups (OS n = 109, ES n = 58) but 6-month postoperative autonomy level was better after ES ( p = 0.01). There was a trend towards better survival after OS (74% at 1 year, 62% at 2 years, 32% at 4 years with OS and 68%, 50%, 17% respectively for ES p = 0.06), but no difference regarding limb salvage (91% at 1 year, 90% at 2 years, 89% at 4 years for OS and 94%, 87%, 86% respectively for ES, p = 0.939) and primary patency (76% at 1 year, 59% at 2 years, 50% at 4 years for OS and 82%, 75%, 32% respectively for ES, p = 0.467). Conclusions ES is justified in CLI octogenarians, because it allows restoring a higher autonomy level, with limb salvage and patency rates comparable to OS.
