Abstract：Objective To investigate the clinical efficacy of a modified rhomboid flap,based on the dense area of the superior and inferior gluteal artery perforator groups,combined with continuous dual negative pressure drainage in the treatment of stage Ⅳ sacrococ-cygeal pressure ulcers.Methods A retrospective analysis was conducted on the clinical data of 22 patients with stage Ⅳ sacrococcygeal pressure ulcers admitted to the Department of Burns and Plastic Surgery,Dongguan People's Hospital,from January 2021 to June 2023.The cohort with wound areas ranging from 5 cm × 5 cm to 10 cm × 11 cm.After thorough preparation of the wound bed during the periop-erative period,all patients underwent repair using the modified rhomboid flap based on the superior and inferior gluteal artery perforator groups,followed by postoperative placement of continuous dual negative pressure drainage.Postoperative flap survival,wound drainage volume,complications,and recurrence of pressure ulcers were observed,along with follow-up evaluation of flap appearance and function-ality.Results All 22 patients achieved flap survival postoperatively,with no complications such as fat liquefaction,infection,or poor flap healing.The average wound healing time was(14.5±3.2)days.The surgical area exhibited good aesthetic outcomes,appearing naturally full and demonstrating strong pressure and abrasion resistance.The average hospital stay was(16.2±2.3)days.During follow-up 6 months to 1 year,no pressure ulcer recurrence was observed.Conclusion The modified rhomboid flap based on the superior and inferior gluteal artery perforator groups combined with continuous dual negative pressure drainage is a simple and minimally invasive procedure.It demonstrates effective outcomes in the repair of stage Ⅳ sacrococcygeal pressure ulcers,with minimal intraoperative trauma and bleeding,and holds significant clinical value.
