Fingertip replantation in young children is difficult, especially in cases with amputation at subzone 1. Replantation is preferred whenever possible, but the identification of vessels of operative size can be very challenging. Non-enhanced angiography (NEA; Genial Viewer; Genial Light, Shizuoka, Japan) emits infrared light with the wavelength of 850 nm, which is exclusively absorbed by haemoglobin. The light penetrates the bones and other soft tissues, effectively visualising vessels containing blood, and the image is shown in real time on the screen of a laptop computer. We present a case in which preoperative NEA visualised vessels in the amputated fingertip, allowing a successful replantation in a 2-year-old boy. By taking the guesswork out of vessel localisation, NEA can be useful in expanding operability of replantation surgery in fingertip amputations.
小儿指尖再植困难，尤其是在亚区 1 切断的情况下。只要有可能，就应进行再植，但识别手术大小的血管可能极具挑战性。非增强血管造影术（NEA；Genial Viewer；Genial Light，静冈，日本）发出波长为 850nm 的红外光，该光仅被血红蛋白吸收。光线穿透骨骼和其他软组织，有效地可视化含血液的血管，图像实时显示在膝上型计算机的屏幕上。我们报告了一例患儿，术前 NEA 可显示断指指尖的血管，从而成功再植了一名 2 岁男孩的手指。通过消除血管定位的猜测，NEA 可在指尖离断再植手术中扩大手术可行性。
