摘要
目的阐述颈内动脉颈段走行异常的临床表现特点及影像学研究方法。方法回顾性分析2004年5月至2011年4月7例颈内动脉颈段走行异常患者的临床资料,其中2例为术中直接探查颈段颈内动脉,3例采用影像后处理工作站对颈动脉cT血管造影(CTangiography,CTA)原始水平位图像行最大密度投影,2例行MRA检查。结果颈内动脉颈段走行异常中5例患者无相关临床症状,1例表现为咽部异物感,另外1例表现为咽痛。查体4例患者可见鼻咽、口咽或喉咽咽壁的搏动性肿物,表面光滑。观察颈内动脉共12条,均有颈内动脉颈段走行异常,其中血管迂曲5条,发生扭结7条。有影像学资料的5例患者中双侧颈内动脉颈段均受累,其中2例双侧均为迂曲,2例双侧均为扭结,1例两侧分别为迂曲和扭结同时发生。结论颈内动脉颈段走行异常的临床症状不典型,查体或可发现咽部隆起,或出现异常搏动。CTA和MRA可直观显示颈内动脉颈段走行异常,以避免术中损伤。
Objective To introduce the clinical manifestations and compare the different radiological methods of detecting the malformation of cervical segment of internal carotid artery. Methods A retrospective analysis of 7 cases with malformation of cervical segment of internal carotid artery between May, 2004 and April, 2011 was conducted. CT angiography (CTA) and magnetic resonance angiography (MRA) were used to detect the morphology of cervical segment of internal carotid artery. Results This disease entity provided no obvious symptoms in five cases, and only such complaints as pharyngeal foreign body sensation in one and odynophagia in another were described. Physical examination showed a bulge with pulsation on pharyngeal wall in four cases, and apparent normal pharynges in other three patients, all of which were covered with intact pharyngeal mucosa. Twelve carotid arteries in seven cases were observed, five of which showed tortuosities and seven kinkings. All of the five patients with recorded radiological examination had identified malformations of internal carotid artery, two of which were tortuosities bilaterally and two kinkinks bilaterally and one tortuosity and kinking respectively. CTA and MRA revealed tortuosities of cervical segment of internal carotid arteries. Conclusions No typical clinical symptoms were found in the malformation of cervical segment of internal carotid artery. Pharyngeal bulge with pulsation could be encountered. CTA and MRA showed excellent ability to depict the malformation of cervical segment of internal carotid artery and its relationship with surrounding structures, which could protect carotid artery from unintended damage.
