Cerebral infarction patterns induced by intracranial and extracranial artery concurrent stenosis
摘要
Abstract
Objective To explore the cerebral infarction patterns induced by intracranial and extracranial artery concurrent stenosis. Methods The condition of intracranial and extracranial artery concurrent stenosis in 185 patients with acute ischemic stroke were checked by CT angiography (CTA). MR diffusion-weighted imaging (DWI) were performed to definite infarction patterns. The infarction patterns were classified as; single or multiple infarct; perforator artery infarct (PAI) , pialartery infarct (PI) , border-zone artery infarct (BZI) , large territorial infarct. The infarction patterns of concurrent stenoses and nonconcurrent stenoses were compared with each other. Results There were 69 patients with concurrent stenoses, including tandem lesions 49 cases and nontandem lesions 20 cases. There were 99 patients with nonconcurrent stenoses and 17 patients without stenoses. The rates of multiple infarction and PAI + PI + BZI in concurrent stenoses group (55. 1% , 20. 3%) were significantly higher than those in noconcurrent stenoses group(34. 3% ,5.1%) (all P < 0. 01) ; while the rate of single small PAI (24. 6%) in concurrent stenoses group was significantly lower than that in the noconcurrent stenoses group (48.5%) (P < 0. 01). The rates of multiple infarction and PAI + PI + BZI in the tandem stenoses subgroup of concurrent stenoses group (65. 3% , 26. 5%) were significantly higher than those in the nontandem stenoses subgroup (30% , 5%) (P < 0. 05 -0. 01) ; while the rate of single small PAI (14. 3%) in the tandem stenoses subgroup was significantly lower than that in the nontandem stenoses subgroup (50. 0%) (P < 0. 01). Conclusion The patterns of multiple infarction and PAI + PI + BZI are more in cerebral infarction patients induced by intracranial and extracranial artery concurrent stenoses.关键词
