摘要：

目的    评估CT血管造影（CTA）在皮瓣转移修复口腔癌术后组织缺损的临床价值。方法    对2003年1月至2010年8月中山大学附属第五医院口腔颌面外科诊治的7例口腔癌患者，术前行16层螺旋CT增强扫描，显示病灶范围及与周围组织关系，并行CTA及三维重建，显示颈部动、静脉及分支和皮瓣转移区的血管影像。结果       CT增强扫描并行CTA和三维重建后可明确病灶范围和颈部血管供血情况，对拟转皮瓣区域的血管情况可提供直观图像，为手术切除范围和选择修复方法提供合理参考。结论    16层螺旋CT增强扫描加CTA和三维重建能准确、直观地显示手术应切除的范围和血管形态，对手术方式及修复方法的选择有重要价值。

Abstract:

Objective    To evaluate the clinical value of computed tomography angiography （CTA） in skin flap repair of tissue defect following oral carcinoma ablation. Methods    Seven patients with oral carcinoma were subjected to 16-row spiral computed tomography（CT） scan，CTA and three-dimensional reconstruction， displaying exairesis ambit，relationship with surrounding tissue，blood vessel picture of arteriovenous and branch of cervical part and transfer of skin flap region. Results    CT scan，CTA and three-dimensional reconstruction can help to identify the ambit in focus of infection and blood supply of cervical part blood vessel，which also helped to provide direct picture of blood vessel information in skin flap region so as to provide reasonable reference in exairesis ambit and selection of restorative procedure. Conclusion    16-row spiral CT  scan，CTA and three-dimensional reconstruction can accurately and intuitively display exairesis ambit and blood vessel morph；they have  important value to choices of modus operandi and restorative procedure.
