Abstract:
Objective To compare the difference of ultrasound and digital subtraction anginography (DSA) in diagnosing carotid atheriosclerosis. Methods A total of 340 patients of ischemic cerebrovascular disease with carotid atheriosclerosis were examined with ultrasound and DSA. They were divided into cerebral infarction group (n=235) and transient ischemic attack (TIA, n=105), and also were divided into the young-aged group (n=54), middle-aged group (n=137) and old-aged group (n=149) by age. Results Both of the ultrasound and DSA found that the incidence of carotid artery stenosis in cerebral infarction was higher than that in TIA (P<0.05);the incidence that of carotid artery stenosis in old-aged group were higher than that in middle-aged and young-aged group (P<0.05), and in middle-aged group was higher than that in young-aged group. Taking DSA as standard, the accordance rate of ultrasound in diagnosing stenosis, clot and both of them were 89.39%, 80.85%, 87.15%, respectively. Conclusion Carotid artery ultrasound has high sensitivity in diagnosis of carotid atheriosclerosis. Either carotid artery ultrasound or DSA has advantages. With combination of two methods, there will be an important significance in the diagnosis, clinical treatment, assess before operation and follow-up after operation in patients with carotid atheriosclerosis.
