The growing prevalence of this condition and the associated healthcare costs make it an important public health objective. Diagnostic criteria for Critical Limb Ischaemia differ between learned societies and countries.\n\nIts diagnosis is most frequently based on the combination of a clinical criterion (ischaemic decubitus pain and\u002For necrotic wounds, with a time to onset \\> 2 weeks) and a haemodynamic criterion (ankle systolic pressure (ASP) \\\u003C 50mmHg or toe systolic pressure (TSP) \\\u003C 30 mmHg or transcutaneous oxygen pressure (TCPO2) \\\u003C 30 mmHg).\n\nRecent studies have highlighted the importance of pulsed Doppler flow analysis in quantifying arteriopathy of the lower limbs, both by systematically analysing flow modulation and by measuring the systolic rise time of distal arteries (dorsal artery of the foot and lateral plantar artery).\n\nThe main aim of this study is therefore to validate a reliable and accessible diagnostic tool for screening patients suffering from CLI so that they can be referred to a reference centre as early as possible.",[90],"Critical Limb Ischemia",[92,93],"systolic rise time","critical limb ischaemia","2024-08-27",{"date":96,"type":97},"2024-08-29","ACTUAL",{"date":99,"type":97},"2024-07-01",{"date":101,"type":86},"2026-09-01",{"name":5,"class":6},3]
