Abstract :The cervical segment of internal carotid artery insert ignore into journalissuearticles values(cICA); usually has straight vertical course without any branching. In the present study, variations of the cICA were evaluated based on the three-dimensional volume rendered neurovascular images. The computed tomography angiography images of 56 patients, diagnosed with subarachnoid hemorrhage insert ignore into journalissuearticles values(SAH);, were evaluated retrospectively. Two separate researchers, blinded to each other and clinical information of the patients, evaluated the courses of cICA bilaterally. The variations were classified as tortuosity, kinking, and coiling. Total 112 cICA segment of 56 patients were evaluated. The cICA variations were present in 21.4% of patients and 17.9% of segments. There was tortuosity in 5 insert ignore into journalissuearticles values(8.9%); patients, kinking in 4 insert ignore into journalissuearticles values(7.1%); patients, and coiling in 6 insert ignore into journalissuearticles values(10.7%); patients. Of 41 patients with aneurysmal SAH, there was a cICA variation in 8 insert ignore into journalissuearticles values(19.5%); patients. A cICA variation was detected in 4 insert ignore into journalissuearticles values(26.7%); of 15 patients with idiopathic SAH. The cICA variation ratio in SAH patients was concordant with studies performed in different patient groups. Although the ratio was slightly higher in idiopathic SAH patients, there was no statistical significance between aneurysmal and idiopathic SAH groups. The coiling was more frequent in SAH patients compared to previous studies. The cICA variations tend to be bilateral in SAH patients.
