报告３例头颈部恶性肿瘤颈部转移累及颈动脉，术中保留预动脉，术后４～６ｄ颈动脉破裂大出血。分析原因为伤口感染和颈动脉已被肿瘤浸润所致，提示受肿瘤侵犯的颈动脉不宜保留。 Three cases of neck metastases involving the carotid artery were reported. The prearterial artery was preserved during the operation and the carotid artery ruptured in 4 to 6 days after surgery. The reason for the analysis was that wound infections and carotid arteries have been caused by tumor infiltration, suggesting that carotid artery invasion by tumors should not be preserved.
