摘要: Abstract It is crucial to monitor spatio-temporal changes in the microcirculation of flaps. A laser speckle imaging technique based on contrast analysis compensates for disadvantages and can assess regional blood flow distribution at high resolution. In this paper, temporal circulation were investigated with full-field perfusion (FLPI) rat dorsal delay random Twenty Sprague–Dawley rats randomized into two groups (delay procedures controls) a standardized pattern flap (caudally based, 3 × 10 cm). Blood dynamics both studied FLPI different timepoints, size surviving necrotic areas flaps, vessel distribution, microvessel density diameters appraised. The results showed that after secondary elevation did not rapidly decrease group compared control group. Viability skin diameter, micro-vessel was significantly improved Delay procedure work by diminishing resistance real-time detection, could be better method studying judging vascularity.
