SURVIVAL OF PEDICLED PERFORATOR FLAPS IN LOWER-LEG SOFT-TISSUE RECONSTRUCTION: AN ANALYSIS OF INFLUENCING FACTORS
Nội dung chính của bài viết
Tóm tắt
Objectives: To evaluate the survival of pedicled perforator flaps and analyze related factors, including rotation angle, pedicle diameter, pedicle length, and flap size. Methods: A cross-sectional descriptive study was conducted on 55 patients with lower-leg soft-tissue defects treated with pedicled perforator flaps. The effects of flap rotation angle, pedicle diameter, and pedicle length on flap survival were analyzed. Results: 96.4% of flaps survived, achieving effective coverage. Flap width and defect size were significantly associated with flap survival. Pedicle length showed an inverse correlation with flap survival (OR = 0.3). Conclusion: Pedicled perforator flaps represent a reliable option for reconstruction of lower-leg soft-tissue defects. Flap width and defect size are associated with the risk of flap necrosis. A pedicle diameter of ≥ 0.5 mm is safe for flap survival.
