Complications and limitations
Complications and limitations
One drawback to the traditional V-Y advancement flap is its relatively limited mobility. In rare cases, it may become clear intraoperatively that a V-Y flap will not be sufficiently mobile to permit defect closure; in such cases, alternative approaches, such as a skin graft, may be explored.119 A retrospective study in spinal cord-injured patients after pressure ulcer reconstruction in patients with either fasciocutaneous or myocutaneous flaps found suture line dehiscence to be the most common complication, followed by infection, hematoma, partial flap necrosis, and total flap necrosis.122 In a
systematic review including 13 studies of patients treated using fasciocutaneous flaps, the overall complication rate and recurrence rate were 11.7% and 11.2%, respectively.110 Risk factors for dehiscence and recurrence in patients receiving flap therapy for coverage of pressure ulcers in another retrospective study included poor diabetes control, prealbumin of less than 20 mg/dL, history of same-site flap failure, ischial wound location, and young age at surgery time.123
