Abstract：Objective To observe patients with acute ischemic infarct in the anterior choroidal artery (AchA) territory and to investigate stroke evolution in patients with AchA infarction.Methods A prospective series of 96 patients with acute iscbemic lesion in the AchA territory.Within 1 week of admission,according to national institute of health stroke scale (NIHSS) score a total of 96 patients were divided into two groups:neurological deterioration group (group A,42 cases) and no deterioration groups (group B,54 cases).All patients underwent doppler ultrasonography of the cervical arteries,computed tomography angiography or magnetic resonance angiography.Two groups were compared regarding carotid atherosclerosis and vascular stenosis.Results In patients of AchA territory,the two groups were characterized by hypertension.The constituent ratio of diabetes and hyperlipidemia in group A [35.7％ (15/42),59.5％ (25/42)] was higher than that in group B [14.8％ (8/54),37.0％ (20/54)].There were 30 cases (71.4％)with unstable plaque in group A,significantly more than that in group B [21 (38.9％)] (x2 =4.42,P =0.036).The proportions of cerebrovascular steno-occlusion in group A (33 cases,78.6％) was significantly higher than that in group B(31 cases,57.4％) (x2 =4.76,P =0.029).27 patients of group A with ipsilateral internal carotid artery(ICA) and/or middle cerebral artery(MCA) steno-occlusion (64.3％) were significantly more than those in group B (x2 =6.10,P =0.014).After 3 months 12 patients (30.0％) in group A had improvement,which was much lower than that (28 cases,54.9％) in group B(x2 =5.64,P =0.01 8).Conclusion Diabetes and hyperlipidemia may be the important factors affecting the progress of AChA infarcts.
