下肢缺陷可能是由于多种病因引起的，如外伤、外周动脉疾病、糖尿病足部感染、肿瘤切除、枪伤和烧伤等。根据受影响的解剖部位、组织量和组织成分，下肢缺陷表现出广泛的临床表现。本研究旨在介绍双蒂瓣片在无法进行游离瓣片等显微外科修复的情况下的简便可靠的挽救方法。对2018年3月至2021年9月期间下肢软组织缺陷的患者进行了回顾性研究。在这些患者中，使用双蒂瓣片进行修复的患者纳入了研究。对患者进行至少12个月的定期随访。在随访期间，拍摄患者照片，对瓣片存活、创面裂开和软组织感染进行体格检查，并记录数据。本研究回顾性分析了23例下肢缺损患者，他们采用随机双蒂瓣片进行修复。在4例患者中，缺损部位位于腿的中部1/3，而在19例患者中，缺损部位位于腿的远端1/3。22例患者的瓣片设计采用纵向设计，1例患者的瓣片设计采用横向设计。14例患者采用一块双蒂瓣片进行缺损修复，9例患者采用两块双蒂瓣片进行缺损修复。16例患者在供区修复中使用皮片移植，7例患者则进行了原位修复。术后期间，有5例患者出现局部软组织感染，3例患者出现创面裂开，通过抗生素治疗、重新缝合和适当的伤口护理实现了顺利愈合。在任何患者中都没有发生瓣片或皮片丢失等重大并发症。随机双蒂瓣片是重建中、远端下肢缺损的非常可靠的选择。我们认为，这是一种可以安全应用于下肢小、中等大小缺损的重建选择，因为即使患有对伤口愈合产生不良影响的糖尿病和外周动脉疾病等合并症的患者，也可以使用该方法。

Lower extremity defects may occur due to many etiological causes such as trauma, peripheral arterial disease, diabetic foot infections, tumor resection, gunshot injuries, and burns. Lower extremity defects show a wide clinical presentation ac-cording to the affected anatomical localization, amount of tissue, and tissue content. In this study, it is aimed to present the use of bipedicled flaps as a simple and reliable salvage method in cases where microsurgical repairs such as free flaps are not possible.Patients with soft-tissue defect in their lower extremities between March 2018 and September 2021 were scanned retrospectively over the file. Among these patients, patients who were repaired with a bipedicle flap were included in the study. The patients were followed up regularly for at least 12 months. During the follow-ups, the patients were photographed, a physical examination was performed in terms of flap viability, wound dehiscence, and soft-tissue infection, and the data were recorded.In this study, 23 patients with a defect in the lower extremity who were repaired with randomized bipedicled flap were retrospectively analyzed. In four patients, the location of the defect was located in the middle 1/3 of the leg, while in 19 patients, it was located in the distal 1/3 of the leg. The flap design was done vertically in 22 patients, and the flap design was done transversely in one patient. One bipedicled flap was used for defect repair in 14 patients, and two bipedicled flaps were used for defect repair in nine patients. While skin grafts were used for donor site repairs in 16 patients, the donor site was primarily repaired in seven patients. In the post-operative period, local soft-tissue infection was detected in five patients and dehiscence at the wound site in three patients, and uneventful healing was achieved with antibiotic therapy, resuturation, and appropriate wound care. No major complications such as flap or graft loss were experienced in any of the patients.Randomized bipediculated flaps are a very reliable option for the reconstruction of middle and distal lower extremity defects. We think that it is a reconstruction option that can be safely applied in small and medium-sized defects of the lower extremity, since it can be used even in patients with comorbidities such as diabetes mellitus and peripheral arterial disease that adversely affect wound healing.
