Excision and clinical application of ALTPF based on lateral branch of the lateral femoral circumflex artery descending branch / 中华显微外科杂志

ABSTRACT

Objective:To investigate the removal of ALTPF pedicled with the lateral branch of the descending branch of the lateral femoral circumflex artery and its application in wound repair.Methods:From January, 2019 to March, 2021, 32 cases of limb wounds were repaired with ALTPF pedicled with the lateral branch of the descending branch of the lateral femoral circumflex artery, including 25 males and 7 females. The age ranged from 21 to 63 years, with an average of 34 years. Injury mechanism there were 12 cases of traffic accident injury, 8 cases of machine injury, 6 cases of heavy object crushing injury and 6 cases of chronic infectious wound. The area of soft tissue defect was 8.2 cm × 6.3 cm-18.6 cm × 11.2 cm. There were 25 cases of direct suture and 7 cases of free skin grafting. All patients who needed flap repair underwent CTA and high-frequency CDU before operation to judge the approximate direction of the lateral branch of the descending branch of the lateral femoral circumflex artery and the position of the perforating branch. All patients were followed-up regularly for 3 - 13 months, with an average of 11 months.Results:All patients who underwent free flap surgery had no vascular crisis and the flap survived smoothly. At the last follow-up, the appearance of the flap was beautiful without bloating and there were no complications in the donor area.Conclusion:Compared with the traditional ALTPF, the perforator flap of the lateral branch of the descending branch of the anterolateral femoral artery is relatively simple, which can replace the traditional ALTPF to a certain extent, and is worthy of popularization and application in clinic.
