title: A new device expanding operability of fingertip replantation: subzone 1 fingertip replantation assisted by non-enhanced angiography in a 2-year-old boy.
abstract: 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.
