Implantable Doppler probe for flap monitoring
Implantable piezoelectric ultrasonic probe (20MHz) fixed around the vascular pedicle (typically the vein) with a silicone cuff, connected to an external battery-powered monitor.
How it is used
Continuous postoperative monitoring of free-flap perfusion, especially for buried/non-visible flaps where clinical (visual/capillary refill) monitoring is not possible.
Clinical tip
The cuff is usually secured with two microclips or fibrin glue; for large-diameter vessels, suture fixation is sometimes needed because the cuff may lack redundant silicone.
