Survival, Limb Salvage, and Management of Patients with Lower Limb Acute Ischaemia: A French National Retrospective Observational Study.

Résumé

Objective The aim was to describe the baseline characteristics of French patients referred with acute limb ischaemia (ALI), and their clinical management and outcome (death, amputation). Methods This retrospective observational cohort study used the National Health Data System. All adults hospitalised for ALI who underwent revascularisation with an endovascular or open surgical approach between 1 January 2015 and 31 December 2020 were included and followed up until death or the end of the study (31 December 2021). A one year look back period was used to capture patients’ medical history. The risks of death, and major and minor amputations were described using Kaplan–Meier and Aalen–Johansen estimators. A Cox model was used to report the adjusted association between groups and risk of death and Fine–Gray models for the risk of amputations considering the competing risk of death. Results Overall, 51 390 patients (median age 70 years, 69% male) were included and had a median follow up of 2.7 years: 39 411 (76.7%) were treated with an open approach and 11 979 (23.3%) with a percutaneous endovascular approach. The preferred approach for the revascularisation varied between French regions. The one year overall survival was 78.0% and 85.2% in the surgery and endovascular groups, respectively. The surgery group had a higher risk of death (hazard ratio [HR] 1.17, 95% CI 1.12 – 1.21), a higher risk of major amputation (sub-distribution HR 1.20, 95% CI 1.10 – 1.30) and lower risk of minor amputation (sub-distribution HR 0.66, 95% CI 0.60 – 0.71) than the endovascular group. Diabetes and dialysis increased the risk of major amputation by 52% and 78%, respectively. Subsequent ALI was the third most common cause of hospital re-admission within one year. Conclusion ALI remains a condition at high risk of death and amputation. Individual risk factors and ALI severity need to be considered to choose between approaches. Continued prevention efforts, improved management, and access to the most suitable approach are necessary.
