Description
Summary:Angiosome-directed endovascular therapy for the treatment of chronic limb-threatening ischemia (CLTI) remains controversial owing to the overlap of wound angiosomes. Angiographic grading of success has limitations and translesional pressure assessments are seldom performed in the infrapopliteal vessels. Objective criteria to determine revascularization success in tibiopedal vessels have not been well described. Quantifying perfusion to a wound bed after establishing direct or indirect (via collateral) flow after revascularization is an important component for treating CLTI patients yet is seldom performed. We report the use of fluorescent angiography to quantitatively examine perfusion of a diabetic foot ulcer before and after angiosome-directed endovascular therapy.
