Laser Speckle Contrast Imaging, a Feasible Device for Monitoring Postoperative Microcirculation: A Case Report

Author(s): Muhsin Billah Bin Khashru, Zeng-tao Wang, Bilkis Akthar

Ensuring uninterrupted microcirculation is a fundamental requirement for reconstructive flap surgeries, and tissue viability can be determined by measuring the perfusion to it. There are several laser-based optical imaging procedures have been established to analyze tissue perfusion. Laser speckle contrast imaging (LSCI) is one of them comprising a camera and laser diode that produces a near-infrared laser beam and illuminate the tissue. Over the illuminated area, a scattered speckle pattern is created and measures the perfusion rate. Here we report a case in which post-operative perfusion monitoring of tissue flap was done using the LSCI. Minimal invasive, easy to operate, real-time perfusion measurement, and rapid response to vascular occlusion makes LSCI a prevalent device for measuring pre-, peri- and post-operative microcirculation. However, broaden clinical studies should be necessary to confirm its effectiveness. According to our studies, we found LSCI to be a potential monitoring device.
