Needling as a Potential and Novel Treatment for Skin Ischemia following Filler-Induced Vascular Occlusion: A Case Series

All of the 4 cases recovered from skin ischemia without side effects by receiving needling procedure. The available data demonstrate some potential mechanisms of needling, such as embolus releasing, ischemia reperfusion and revascularization. Although there is a lack of conclusive evidence for improving the hypoperfusion area by needling treatment, the current cases observation and theoretical analysis as well as our cases provide evidence supporting its potential as an efficacious, simple, and secure treatment for vascular complications.
