Efficacy and safety of surgical excision and reconstruction combined with radiotherapy for huge keloids: A 13-year experience.

Background: Surgical excision combined with radiotherapy is considered an effective treatment for keloids, while the efficacy and safety of this regimen for huge keloids in patients who need reconstruction after excision is still unclear. Therefore, this study aimed to evaluate the efficacy and safety of surgical excision and reconstruction combined with radiotherapy for huge keloids in a single center with 13 years of experience.

Methods: All consecutive patients with huge keloids who underwent surgical excision and reconstruction combined with radiotherapy were identified.

Application of epinephrine mixed with local anaesthetics in injection sclerotherapy of early-stage arteriovenous malformation.

Purpose: To explore the effect of epinephrine mixed with local anaesthetic injection on blood flow control in early stage arteriovenous malformation (AVM) and explore suitable cases.

Methods: Twenty-five patients with early stage (Schobinger clinical stage I/II) AVM were selected between September 2019 and March 2022. Local anaesthetics containing epinephrine were injected around the nourishing artery and into lesions under the guidance of ultrasound, and the blood flow distribution grade in the lesions as well as the changes in diameter, peak systolic velocity (PSV), and resistance index (RI) of the nourishing arteries and vessels in the lesions were observed to determine the type of AVM suitable for epinephrine injection.

Application of VSD technique in adults with chronic osteomyelitis of the extremities combined with soft tissue defects.

To investigate the clinical application of vacuum sealing drainage (VSD) in chronic osteomyelitis of the extremities combined with soft tissue defects in adults. This study retrospectively included 32 adult patients with clearly diagnosed chronic osteomyelitis of the extremities combined with local soft tissue defects, and the trauma was covered by VSD after debridement, osteotomy, and vancomycin-laden bone cement filling of the occupancy, and the trauma was covered by selecting a suitable flap transfer repair according to the site and extent of the soft tissue defect after the trauma condition was suitable, and the secondary trauma was taken from the abdominal full-thickness skin free skin slice graft, according to whether the skin graft area was performed. The skin flap hematoma and infection rate, as well as the skin flap survival rate and implant fixation time were compared and analysed between the two groups.
