Background: Our aims were to describe macro- and microvascular disease by the use of a combination of toe blood pressure (TBP) and transcutaneous oxygen pressure (TcPO2) measurements, and through this approach we aimed to classify lower limb ulcers. One specific aim was to evaluate whether patients with diabetes had a more pronounced disturbance of the microcirculation compared to patients without known diabetes.
Methods: The study included a series of 498 patients with suspected critical lower limb ischemia.
