Abstract:
Objective To investigate the incidence of atherosclerotic renal artery stenosis (ARAS), the relationship between ARAS and cerebral artery stenosis, and the risk of ARAS in patients with brain infarction. Methods The clinical data of 1 650 brain infarction patients were analyzed, which were carried out digital subtraction angiography(DSA) of cerebral and renal artery.The incidence of ARAS was counted out, and the relationship was analyzed between the different degree and number of cerebral artery stenosis and the rate of RAS. The demographic characteristics and the common risk factors of atherosclerosis were recorded, and the risk factors of ARAS were analyzed. Results The rate of ARAS in moderate stenosis group and severe stenosis and occlusion group of cerebral artery were all significantly higher than that in mild stenosis group and no stenosis group (all P < 0.01). The rates of ARAS in severe stenosis and occlusion group were significantly significantly higher than those in moderate stenosis group (P < 0.01). The rates of ARAS in 2 branch stenosis group and ≥3 branch stenosis group were both significantly higher than those in no stenosis group and 1 branch stenosis group (P < 0.01). The rates of ARAS of ≥3 branch stenosis group were significantly higher than those in 2 branch stenosis group (P<0.05). The rate of ARAS of 1 branch stenosis group were significantly higher than those in no stenosis group (P < 0.05). Age, hypertension, moderate or more artery stenosis or occlusion, and≥2 branch stenosis was independent risk factor of ARAS. Conclusions The incidence of ARAS increasesd with the increase of the degree of cerebral artery stenosis and the number of branch involved.Older age, hypertension, moderate or more artery stenosis or occlusion, and≥2 branch stenosis is risk factor for ARAS.
