[摘要]目的：探讨CTA(CT血管造影)对指导游离股前外侧肌皮瓣制备的辅助价值及该皮瓣在舌癌术后缺损修复中的临床效果。方法：对17例明确诊断为舌鳞形细胞癌的患者，术前采用CTA辅助定位旋股外侧动脉降支的穿支血管，选取以该穿支血管为蒂的股前外侧肌皮瓣游离移植修复舌癌术后软组织缺损。结果：所有患者术前CTA辅助定位穿支血管的皮瓣制备在术中按计划均获成功，游离移植肌皮瓣全部存活。术后随访6～36个月，患者舌体形态、功能恢复良好，无明显吞咽及言语功能障碍，局部未见肿瘤复发，供瓣肢无功能障碍。其中1例(T4N2M0)于术后12个月合并肝、肺转移后死亡。结论：CTA辅助定位旋股外侧动脉穿支血管的方法可靠、实用，游离股前外侧肌皮瓣是修复舌癌术后软组织缺损较为理想的选择。

    Abstract： Objective The aim of the study was to investigate the auxiliary value of computed tomography angiography(CTA) in assisting the preparation of free anterolateral thigh myocutaneous flap(ALTMF) and the clinical effect of ALTMF for the reconstruction of postoperative defects after radical resection of tongue carcinoma. Methods CTA were used to locate the perforating vessel of lateral circumflex femoral artery (LCFA) in all cases who were diagnosed as tongue carcinoma ......
