Abstract
Objective Atherosclerotic plaques in basilar arteries of isolated pontine infarction were investigated by high-resolution magnetic resonance imaging ( HR-MRI). Methods Patients suffered from isolated pontine infarction who were underwent high resolution magnetic resonance imaging of basilar arteries in our stroke center were analyzed. To exam-ine the BA basilar artery wall,3. 0T HR-MRI sequences including T2weighted imaging (T2WI),T1weighted imaging (T1WI) and T1enhancement scanning were performed. The plaque and its characteristics of basilar artery at the maximal stenosis between PPI (paramedian pontine infarction) and SDPI ( small deep pontine infarction),were analyzed and com-pared. Results Included in this study were 55 patients with acute isolated pontine infarction,37 with PPI and 18 with SD-PI. The rates of basilar arterial atherosclerotic stenosis (≥50% ) were 58. 8% and 38. 9% ,respectively. There was no sig-nificant difference between PPI and SDPI (P=0. 214). HR-MRI detected underlying atheromatous plaques without basilar arterial stenosis (branch atheromatous disease,BAD) in 14 of 16 patients (87. 5% ) with PPI,which was more common than that of patients with SDPI and without basilar arterial stenosis (16. 7% ,P=0. 001). Compared with patients with SD-PI,plaque enhancement in BAD was more frequently observed in PPI (35. 1% vs 5. 6% ,P=0. 018). Conclusion Basilar arterial atherosclerosis is a common cause of both PPI and SDPI. BAD with plaque enhancement is frequently detected in PPI,but few in SDPI.关键词
