Knowledge of invasion of the walls of the cervical vessels by tumor is of great clinical importance before surgery. We performed sonography on 83 patients with palpable cervical lymph node metastases in the region of the carotid bifurcation to determine the relationship of the metastases to the carotid artery and jugular vein. In all patients, the sonographic results were proved by surgery. The wall of the carotid artery was hypo-echogenic in 11 of 12 patients with surgically proved tumor invasion of the artery. Four results were false-positive. Palpation or swallowing during real-time scanning showed mobility of the tumor relative to the wall of the artery in 47 patients (57%). In these patients, tumor invasion could be excluded. Bilateral compression or invasion of the internal jugular vein was identified correctly with sonography in all five patients in whom this was confirmed surgically. These results suggest that real-time sonography is a valuable method for determining the relationship between cervical lymph node metastases and the carotid artery and jugular vein.
术前了解肿瘤对颈血管壁的侵犯情况具有重要的临床意义。我们对83例在颈动脉分叉区域可触及颈部淋巴结转移的患者进行了超声检查，以确定转移灶与颈动脉和颈静脉的关系。所有患者的超声检查结果均经手术证实。在12例经手术证实肿瘤侵犯动脉的患者中，有11例颈动脉壁回声减低。有4例假阳性结果。实时扫描时触诊或吞咽显示47例患者（57%）的肿瘤相对于动脉壁有活动，在这些患者中可排除肿瘤侵犯。在所有5例经手术证实双侧颈内静脉受压或侵犯的患者中，超声均正确识别。这些结果表明，实时超声是确定颈部淋巴结转移与颈动脉和颈静脉之间关系的一种有价值的方法。
