CONCLUSION
PHN
ADVERSE EVENTS, PHN
In this prospective, single‐armed trial, we first report the feasibility and the safety of autologous fat transplantation to the paravertebral space in preventing PHN. More advantages of this technique including rich in fat content, easy to obtain, cost‐benefit as well as less adverse events makes it a promising treatment method in preventing PHN. The next step toward routine clinical translation is to perform a randomized, blinded, placebo‐controlled trial to investigate the actual long‐term benefice of autologous fat grafting to the paravertebral space in preventing PHN for early HZ.
