[Computed tomographic angiography for evaluation of the relationship between coronary artery stenosis and head and neck artery stenosis].

OBJECTIVE
To evaluate the relationship between coronary artery stenosis and internal carotid artery, vertebral and basilar artery stenosis using computed tomographic angiography.


METHODS
The imaging and clinical data of 84 patients who underwent coronary, head and cervical computed tomographic angiography in our hospital between September 2008 and June 2010 were retrospectively analyzed. Segment stenosis scoring was performed to quantify the degree of stenosis of coronary arteries. The relationship between the segment stenosis scoring and the degree of stenosis for internal carotid artery, vertebral and basilar artery was analyzed.


RESULT
The coronary segment stenosis scores were significantly correlated with the degree of stenosis for internal carotid artery, vertebral and basilar artery (r=0.450 and 0.475,P<0.05) .


CONCLUSION
The degree of the stenosis of coronary artery is associated with the stenosis of internal carotid artery, vertebral and basilar artery, which can be confirmed by computed tomographic angiography."
