ABSTRACT

Objective: To have anatomical measurements of carotid artery bifurcation (CAB) with 64-spiral CT angiography (64-SCTA), and provide anatomic basis for related research. 

Methods: Imaging data of 92 subjects (45 males, 47 females, the age range 20-82 years old and mean age 48.4±6.1) without pathology of CAB, who underwent 64-SCTA in head and neck from June 1, 2008 to June 30, 2010, were selected from the PACS in our hospital. On the 3D images, the angle and size of CAB were measured, and the statistical comparisons of measurements were made between the bilateral, sex and age groups. 

Results:  The measurements of CAB were divided into young(≤ 40 yrs) and older (>40 yrs) groups, that of bifurcation angle is 36.206°±10.210°, 49.343°±16.489° respectively, the inner diameter of common carotid artery (CCA) 6.820±0.635, 6.845±0.838; The proximal inner diameter of internal carotid artery (ICA) is 7.143±0.992, 7.476±1.630 respectively, the enlargement 7.568±1.069, 8.554±1.733, the distal 4.897±0.508, 5.123±0.699; the inner diameter of external carotid artery (ECA) is 4.324±0.580, 4.104±0.638 respectively. There were statistically significant difference in all the measurements between male and female groups, in the bifurcation angle, inner diameters of ICA and ECA between young and older groups and in the bifurcation angle between the left and right (P<0.05).

Conclusions 64-SCTA with 3D image post-processing technique can clearly observe and show the CAB. All of CAB measurements will provide the objective basis for applied anatomy, imaging diagnosis and surgery treatment.
