Detection of perfusion disturbances in digit replantation using near-infrared spectroscopy and serial quantitative fluoroscopy.

Purpose: The postoperative monitoring of digit replants continues to be a challenge. Current objective methods of digit monitoring have not been adopted widely because of their complexity or lack of sensitivity. Because tissue oxygen tension correlates directly with vascular inflow, a device that tracks changes in tissue oxygenation may be useful to monitor the perfusion and viability of digits after revascularization.
