====== Rejection ======

To explore the clinical effects of pedicled omental [[flap]] [[transplantation]] in repairing secondary [[rejection]] [[wound]]s after brain [[pacemaker]] implantation. 
----
A [[retrospective]] [[observational study]] was conducted. From January to August [[2021]], 5 patients with secondary rejection wounds after [[deep brain stimulation]] [[implantation]] who met the [[inclusion criteria]] were admitted to the Wound Repair Center of Ruijin Hospital of Shanghai Jiao Tong University School of Medicine, including 3 males and 2 females, aged 56-69 years, with the [[wound]] developed at the [[pulse generator]] [[implantation]] site in the [[chest]] in 2 cases, at the [[connection]] site of the [[wire]] and [[electrode]] behind the ear in 2 cases, and at both the chest and the back of the ear in 1 case. All the [[wound]]s were repaired by pedicled [[omental flap transplantation]]. The wound area after debridement was 2-15 cm2. After the operation, [[wound healing]] and related complications (pain, infection, incisional hernia, omental flap [[necrosis]], etc.) were observed. During follow-up, the recurrence of the wound was observed.
The wounds of all 5 patients healed within 2 weeks after the operation, without related complications. During follow-up of 12-18 months, 1 patient got a recurrence of rejection wound behind the left ear 4 months after surgery and eventually had the brain pacemaker removed; the other 4 patients had no recurrence of wounds. 
Pedicled omental flap transplantation can repair the secondary rejection wounds after brain pacemaker implantation safely and effectively, with few postoperative complications
