摘　　要：目的:通过髂腹股沟区血管及穿支的解剖学及影像学研究,探讨旋髂深动脉(deep circumflex iliac artery,DCIA)来源的髂骨(肌)穿支嵌合皮瓣的可行性及安全性,为不同复合组织缺损的皮瓣修复方案提供应用解剖学和影像学依据。方法:选取6例12侧中国成人标本,采用双侧股动脉逆行灌注红色乳胶后进行解剖学研究,分析DCIA及其穿支在髂腹股沟区各个层面的分布、走行、长度、管径等特征;同时对12例下肢CTA进行DCIA血管蒂长度、管径、主要分支位置等进行测量,并与解剖学数据进行比较。对2020年8月—2021年11月在南京医科大学附属口腔医院口腔颌面外科就诊的6例下颌骨肿瘤患者,行下颌骨节段性切除术,同期髂骨肌筋膜瓣修复重建,观察患者受区术后外形、咬合功能重建,供区外观和功能恢复情况。采用SPSS 19.0软件包对数据进行统计学分析。结果:6例12侧人体标本髂腹股沟区解剖发现穿腹部浅筋膜层外径>0.5 mm的DCIA穿支共19条,穿支血管分布在髂前上棘后方5 cm,且位于髂嵴内侧5 cm(长)×3 cm(宽)的区域内。DCIA血管蒂长度为(6.73±1.06)cm,血管蒂起始位置外径测量值为(2.55±0.29)mm,DCIA皮穿支穿深筋膜处外径为(1.12±0.14)mm。在12例下肢CTA分析中发现,DCIA血管蒂长度为(6.98±0.62)cm,血管蒂起始位置管径测量值为(2.35±0.20)mm。6例采用髂骨腹内斜肌筋膜嵌合瓣修复下颌骨缺损的患者,髂骨肌瓣均顺利存活。术后随访6~24个月(平均12个月),下颌外形、功能恢复良好,口内肌筋膜瓣黏膜化。术后CT发现植入髂骨无明显体积改变,供区行走、负重基本正常,未出现腹疝等并发症。结论:DCIA及主要分支在髂腹股沟区走行、分布较恒定,可根据不同缺损区情况,制备基于DCIA的不同组织类型嵌合皮瓣以满足修复要求。供区未见明显并发症,是下颌骨缺损修复重建较为理想的选择。PURPOSE:To investigate the feasibility and safety of the deep circumflex iliac artery(DCIA)derived chimeric flap through the anatomical study of the blood vessels and perforating branches in the ilioinguinal region,and to provide the basis for selecting different DCIA chimeric flap schemes according to the difficulty of surgery,defect conditions and repair needs.METHODS:Six Chinese adult specimens were dissected by retrograde perfusion of red latex into bilateral femoral arteries.At the same time,the length,diameter and main branch position of DCIA vascular pedicle were measured in 12 lower limb CTAs,and compared with the anatomical data.Six patients with oral tumors accompanied by mandibular defects who were treated in the Department of Oral and Maxillofacial Surgery,Affiliated Stomatological Hospital of Nanjing Medical University from July 2020 to November 2021 were repaired and reconstructed with the chimeric iliac myofascial flap.The postoperative appearance and occlusal function of the recipient area were observed.SPSS 19.0 software package was used for data analysis.RESULTS:A total of 19 DCIA perforators with an external diameter of≥0.5 mm were found in 12 specimens of ilioinguinal region.These perforators were distributed in the 5 cm×3 cm area,inside the ilium and 5cm behind the anterior superior iliac spine.The length of DCIA vascular pedicle was(6.73±1.06)cm.The measured value of the external diameter of the starting position of the vascular pedicle was(2.55±0.29)mm.The outer diameter of DCIA skin perforator penetrating deep fascia was(1.12±0.14)mm.In the CTA analysis of 12 lower limbs,it was found that the length of DCIA vascular pedicle was(6.98±0.62)cm.The measured diameter at the original position of vascular pedicle was(2.35±0.20)mm.Six cases of mandibular defects were repaired with iliac internal oblique fascia mosaic flap.Six cases of lliac flap survived successfully after operation.Follow up for 6 to 24 months(average 12 months)showed that the mandibular shape and function recovered well,
