成人急性脑梗死合并贫血患者的临床及影像学特点分析

Influence of Anemia on Clinical and Radiological Presentation of Adult Patients with Acute Brain Infarction

目的分析总结急性期脑梗死合并贫血患者的，瞄床、影像学特点。方法回顾分析成人急性期脑梗死合并贫血患者的临床资料，总结其临床特点并分析急性梗死病灶的分布特征。结果八组27例患者，男性14例，女性15例，平均年龄（67．1±11．9）岁（49～84岁），平均血红蛋白浓度（67．5±18．5）g／L（55～107g／L）。该组患者具有如下特点：15例（48．1％）患者卒中危险因素≤1，15例（48．1％）患者出现意识障碍。16例（59．5％）患者表现为急性多发性脑梗死（acute multiple brain infarction，AMBI），12例（75％）的AMBI累及1个以上循环。13例（48．1％）在2周内有卒中复发并加重。结论脑梗死合并贫血患者卒中危险因素少，但急性期内复发率高，出现意识障碍及AM引患者比例较高，累及^个以上循环的AMBI多见。

Objective To analyze and explore the clinical and radiological features of patients with acute brain infarction and anemia. Methods We retrospectively reviewed adult stroke patients with anemia in our hospital consecutively from January l, 2010 to June 30, 2013. Acute brain infarction should be confirmed by diffusion-weighted magnetic resonance imaging. Clinical characteristics and radiological profiles were evaluated. Results Twenty-seven patients （14 males and 13 females） were enrolled, with an average age of（67.1±11.9） years （49-84 years）, and mean hemoglobin concentration of （67.5±18.5） g/L （33-107 g/L）. The patients have following characteristics：13 patients （48.1%） with risk factors for stroke ≤ 1. Thirteen patients （48.1%） had consciousness disturbance. Thirteen patients （48.1%） recurred in two weeks. Sixteen patients （59.3%） presented with acute multiple brain infarction （AMBI）, and 12 patients （75%） of the AMBI involving more than one circulation. Conclusion Brain infarction with anemia is associated with high AMBI rate, high recurrence rate, high consciousness disturbance and less risk factors. AMBI involving more than one circulation is common in acute brain infarction with anemia.
