UNASSIGNED: We present a case of a patient with bilateral necrosis of the anterior third of the tongue, occurring 3 years after chemoradiotherapy treatment for squamous cell carcinoma of the floor of the mouth. Contrast-enhanced CT scan showed multiple areas of stenosis concerning both external carotid arteries and their branches, and total opacification of lingual arteries. Conservative management was performed, with auto-amputation on the fifth day, which allowed healing by secondary intention.
UNASSIGNED: Necrosis of the tongue appears as a rare late complication of radiotherapy, possibly due to its acceleration effect on the atherosclerosis process. Following small-vessel disease, one can assume a higher potential risk of major-vessel disease, highlighting the importance of a routine assessment and prophylaxis of thrombotic events.
■我们介绍了一例双侧舌前三分之一坏死的患者,发生在口腔底鳞状细胞癌的放化疗治疗后3年。增强CT扫描显示多个狭窄区域,涉及颈外动脉及其分支,舌动脉完全混浊。进行保守管理,第五天自动截肢,允许通过次要意图治愈。
■舌坏死是一种罕见的晚期放疗并发症,可能是由于其对动脉粥样硬化过程的加速作用。小血管疾病之后,人们可以假设大血管疾病的潜在风险更高,强调常规评估和预防血栓形成事件的重要性。
