Noninvasive Flap Monitoring using Sidestream Dark Field Microscan: A Method for Real-Time Observation of Submilimmetric Vessels

A timely diagnosis of vascular compromise improves free flap survival. The aim of this study was to determine the feasibility of monitoring flap vascular patency through noninvasive microcirculation monitoring using SDF.
Flap Monitoring using Sidestream

An experimental study was performed in five volunteers. A radial forearm flap was simulated in both upper extremities and cutaneous microcirculation assessment devices were used (SDF and NIRS), and compared with clinical and doppler evaluation.

Conditions of venous occlusion (VO) and total vascular occlusion (TVO) were mimicked by using a cuff. The results of the Microscan SDF monitoring during VO and TVO showed a reduced microcirculatory flow at 16.5 (6-30) and 6 (2-11) seconds respectively.
