Evaluation of the ankle brachial index and toe brachial index for peripheral arterial disease diagnosis in patients over 70 years with lower limb ulcers.

Objective: The aim of our study was to evaluate the diagnostic performance of the ankle brachial index using pulsed Doppler, and the toe brachial index using laser Doppler, in comparison with the arterial Doppler ultrasound of the lower limbs as a reference test, in a population of non-diabetic subjects over 70 years old with lower limb ulcers and without chronic renal failure.

Methods: We included 50 patients, 100 lower limbs from the vascular medicine department of the Paris Saint-Joseph hospital from December 2019 to May 2021.

Results: We found a sensitivity of 54.
