Current methods of postoperative monitoring in microvascular free tissue transfer often prove inadequate in circumstances when complications arise. Acknowledging the room for improvement, a novel system for remote and continuous monitoring of temperature and Doppler ultrasound signals was developed. The system collects data from the transferred tissue, analyzes the data using novel signal-processing algorithms, and wirelessly uploads the results to a secure remote server. Data collected from healthy subjects in a controlled study as well as from a patient recovering from a bilateral breast reconstruction indicate the novel algorithms are capable of detecting arterial and/or venous occlusion from the recorded Doppler ultrasound signal.
