Use of handheld ultrasound Doppler to prevent complications from intra‐arterial injection of dermal fillers: Clinical experience

Summary

A handheld 2 MHz ultrasound Doppler device determines the presence or absence of pulsatile arterial flow immediately beneath the selected site of entry for dermal filler injection. In combination with near infrared technology to map out superficial veins, mishaps from intravascular injections may be reduced. A total of 448 patients aged range between 21 and 74 years, with 168 out of total of 1019 treatment sites having both infrared and ultrasound Doppler assisted preinjection mapping were reviewed. The injection technique is described. Improved patient safety and reduced bruising from asthetic dermal filler injections are potential benefits.
