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.
由于伤口血管体的重叠，血管体导向的血管内治疗慢性肢体威胁性缺血（CLTI）仍存在争议。血管造影成功分级存在局限性，且很少对腘下血管进行跨病变压力评估。确定胫足部血管再血管化成功的客观标准尚未得到很好的描述。在血管再通后建立直接或间接（通过侧支）血流后，量化伤口床的灌注是治疗CLTI患者的重要组成部分，但很少进行。我们报告了使用荧光血管造影术定量检查血管体导向的血管内治疗前后糖尿病足溃疡的灌注情况。
