Enlargement of primary tumor and metastatic lymph nodes in patients with head and neck cancer can be progressive and invade the surrounding vessels despite intensive treatment. Carotid blowout (CBS) tends to occur in these patients, and prompt treatment is required. Surgical management of carotid blowout is technically troublesome because exploration and repair of the previously irradiated or tumor-invaded field are difficult. Endovascular therapy with stent deployment is a good alternative to surgery. Even with such interventional procedures as stent grafting, it is sometimes difficult to obtain favorable outcomes in end-stage patients with poor general conditions. The prophylactic placement of a covered nitinol stent was performed to prevent carotid blowout in a patient with supraclavicular lymph node metastasis from esophageal cancer, and fatal bleeding due to carotid blowout was avoided. The usefulness of the prophylactic placement of a covered nitinol stent for preventing carotid blowout in an end-stage patient is presented.
尽管进行了强化治疗,但头颈癌患者的原发性肿瘤和转移性淋巴结仍可能逐渐增大并侵犯周围血管。这些患者容易发生颈动脉破裂(CBS),需要及时治疗。颈动脉破裂的手术治疗在技术上较为棘手,因为对先前接受过放疗或被肿瘤侵犯的区域进行探查和修复很困难。血管内支架置入治疗是手术的良好替代方案。即使采用支架植入等介入手术,对于一般状况较差的晚期患者,有时也难以取得理想的治疗效果。对一名患有锁骨上淋巴结转移的食管癌患者进行了带覆膜镍钛合金支架的预防性置入,以预防颈动脉破裂,从而避免了因颈动脉破裂导致的致命性出血。本文介绍了带覆膜镍钛合金支架预防性置入在晚期患者中预防颈动脉破裂的有效性。
