Objectives: Current methods evaluating tissue ischemia are based mainly
on evaluating blood flow and not tissue perfusion. However, diabetes mainly
affects small vessels and blood flow evaluation is insufficient. The aim of the
trial was to evaluate the feasibility of NIRS in measuring perfusion changes
during chronic total occlusion (CTO) revascularization in below the knee (BTK)
arteries. Methods and Material: A prospective observational study was
performed. During the endovascular revascularization procedure, tissue
oxygenation changes were measured using three NIRS sensors. Postoperative
angiographies and 30 days wound healing was evaluated. Results: The
study enrolled 30 patients with chronic limb threatening ischemia, occluded below
the knee arteries, Rutherford 5. Mean age 74.7
