Abstract:
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.
