摘要
目的:探讨椎动脉CT血管造影(CTA)在颈椎肿瘤患者中的应用及临床意义。方法:自2007年1月至2009年4月,对肿瘤累及一侧或双侧横突、椎间孔,与椎动脉关系密切的27例患者实施椎动脉CTA,男12例,女15例。年龄7~69岁,平均39.3岁。累及C1或C2者12例,累及下颈椎者15例。结果:1例多骨型纤维异常增殖症患者右侧椎动脉第二段自右侧C5横突孔进入。肿瘤累及右侧椎动脉者10例,累及左侧椎动脉者11例,累及双侧椎动脉者6例。未受累椎动脉通畅。14例患者的肿瘤包绕17支椎动脉,其中11例的14支受累椎动脉直径变细;8例患者肿瘤推挤10支椎动脉,其中6例8支受累椎动脉直径变细;5例肿瘤仅邻近椎动脉,未对椎动脉产生影响。椎动脉第一段受累者4例,第二段受累者10例,第三段受累者9例,同时累及第二和第三段者4例。根据肿瘤的性质实施姑息性切除、经瘤刮除或边缘切除,术中2例累及椎动脉第二、三段的脊索瘤患者一侧椎动脉破裂,行椎动脉结扎,术后无神经功能损害。结论:颈椎肿瘤常累及椎动脉,术前椎动脉CTA能够了解椎动脉与肿瘤和相邻骨结构的关系,评估受累椎动脉及对侧椎动脉通畅情况,指导术中暴露和处理受累椎动脉,避免术前椎动脉栓塞和术中预防性椎动脉结扎带来的潜在风险。
