本文分析了22例大脑中动脉范围脑梗塞。1970年以前及目前对脑栓塞的诊断标准不同。脑栓塞之病因可分为三类,即心源性、动脉至动脉及血流动力学与血液流变学因素致微栓塞。脑栓塞(尤大脑中动脉栓塞)发病率较高、同时临床上发现全身其它脏器栓塞较少,但尸检的发现率较高。脑栓塞在发病初期症状不一定最严重,病程可有波动性。作者强诃发病后48小时内行脑血管造影的必要性。新诊断技术包括二维超声心动图、超声窗扫描、同位素标记血小板闪烁扫描、减数血管造影、X 线 CT 等,能提高对某些心脏病、颈动脉病变、脑栓塞灶等的确诊率。对可疑脑栓塞病例本文推荐了检查步骤。
This article analyzes 22 cases of middle cerebral artery occlusion. Before 1970 and the current diagnostic criteria for cerebral embolism. The causes of cerebral embolism can be divided into three categories, namely cardiogenic arterial to arterial and hemodynamic factors and microvascular embolism. Cerebral embolism (especially middle cerebral artery occlusion) incidence is higher, while the clinical findings of other organs less systemic embolization, but higher autopsy detection rate. Cerebral embolism in the early onset of symptoms are not necessarily the most serious, duration may be volatile. Necessity of intracranial angiography within 48 hours after onset of severe haemorrhage. New diagnostic techniques include two-dimensional echocardiography, ultrasound window scanning, isotope-labeled platelet scintigraphy, subtraction angiography, X-ray CT, can improve the diagnosis of certain heart disease, carotid lesions, cerebral embolism and so on. This article recommended the examination procedure for suspected brain embolism.
