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。
Objective To evaluate the clinical value of CT angiography (CTA) in repairing the tissue defect of oral cancer after flap transfer. Methods Seven patients with oral cancer who underwent oral and maxillofacial surgery in the Fifth Affiliated Hospital of Sun Yat-sen University from January 2003 to August 2010 were examined with 16-slice spiral CT before operation. The relationship between the lesion extent and the surrounding tissues was analyzed. CTA And three-dimensional reconstruction, showing the neck artery, vein and branch and flap metastasis of vascular images. Results Computed tomography (CT) enhanced CTA and three-dimensional reconstruction can confirm the extent of the lesion and the blood supply to the neck vessels. It can provide visual images of the vessel in the flap area and provide a reasonable reference for the scope of surgical resection and the choice of repair methods. Conclusion The 16-slice spiral CT enhanced scan combined with CTA and 3D reconstruction can accurately and directly show the scope of resection and the morphology of blood vessels, which is of great value in the selection of surgical methods and repair methods.
