Abstract: Objective To analyze the common complications after flap surgery and preliminarily summarize their management methods.Methods A total of 313 patients who underwent flap surgery from January 2021 to November 2023 were enrolled,including 18 males and 7 females,aged 3 to 70 years with a mean age of 48.1 years.The clinical data of patients with postoperative complications were analyzed.Results Among the 313 patients who underwent flap surgery,25 cases (8.0%) developed postoperative complications,including 8 cases of partial flap necrosis,11 cases of poor flap wound healing,3 cases of flap congestion,1 case of arterial insufficiency,1 case of donor-site infection,and 1 case of foreign body retention.No case of total flap necrosis was observed.The time of complication occurrence ranged from 1 day to 3 months after surgery.Mild complications could be improved by keeping warm,preventing compression,drug therapy and wound dressing change; severe complications required emergency exploration,wound debridement,skin grafting and even reoperation of flap.Conclusion Appropriate case selection,careful surgical planning,proficient flap surgery techniques and standardized postoperative management are important links to prevent postoperative complications of flap surgery.After the occurrence of complications,early and appropriate management can save most flaps,while a few severe complications need one or more remedial operations.
