Aim: Describe a junctional ischemic stroke without large arterial trunks stenosis associated with an acute coronary syndrome. Case Presentation: A 66-years-old man was admitted for abrupt recurrent right hemiparesis related to bilateral and junctional ischemic stroke lesions. He had a medical history of a vertebrobasilar ischemic stroke concurrent with an acute coronary syndrome with normal coronary arteries. Transthoracic echocardiogram showed small apical akinesia. Hemoglobin level was 18.9 g/dl with a hematocrit of 57.6%. The endogenous erythropoietin was 1.3 mIU/ml with JAK2 V617F mutation positivity (37%). After eight months of treatment (hydroxycarbamide + aspirin + allopurinol) hemoglobin was 12.5 g/dL. Conclusion: This case illustrates the most suggestive features of PV particularly the ischemic stroke junctional topography.展开更多
目的探讨深度单采红细胞术治疗红细胞增多症(PV)的疗效及安全性。方法对9名PV确诊患者,采用深度单采红细胞术治疗,一次性采集10.9U红细胞。监测采血过程,观察患者放血前后皮肤颜色,检测并分析患者放血前后的Hb和Hct的变化。结果 9名患者...目的探讨深度单采红细胞术治疗红细胞增多症(PV)的疗效及安全性。方法对9名PV确诊患者,采用深度单采红细胞术治疗,一次性采集10.9U红细胞。监测采血过程,观察患者放血前后皮肤颜色,检测并分析患者放血前后的Hb和Hct的变化。结果 9名患者经1次深度单采红细胞后,面部及手掌皮肤颜色明显改善,由红紫色变为红色,放血前后Hb (g/L)为197.4±13.7 vs 160.3±26.9,Hct (%)为61.22±3.94 vs 50.14±7.66(P<0.05);放血过程中的不良反应率11.1%(1/9),该患者出现低钙反应(自感口唇发麻)。结论深度单采红细胞疗法治疗PV安全、有效,可减少患者静脉放血次数和药物治疗引起的不良反应。展开更多
