The concept of a "nutrient flap," in which ischemic tissue is nourished by a transferred well-perfused flap, has been advocated for use since the early days of free flap procedures. Several studies have reported cases of no-option chronic limb-threatening ischemia salvaged by nutrient free flap transfer. However, it has been difficult to prove the actual dynamic flow and nutritional vascular formation. Thus, the existence of a nutrient flap has remained unproved. In the present report, we have described the case of free flap transfer for a patient with no-option chronic limb-threatening ischemia in whom we detected evidence of a nutrient flap using indocyanine green fluorescence imaging.
“营养皮瓣”的概念，即通过转移血运良好的皮瓣为缺血组织提供营养，自游离皮瓣手术早期就已被提倡使用。多项研究报告了通过游离营养皮瓣转移挽救无可选择的慢性肢体威胁性缺血病例。然而，很难证实实际的动态血流和营养血管形成。因此，营养皮瓣的存在尚未得到证实。在本报告中，我们描述了一例无可选择的慢性肢体威胁性缺血患者的游离皮瓣转移病例，在该病例中我们使用吲哚菁绿荧光成像检测到了营养皮瓣的证据。
