脑血管造影后迟发的CNS并发症常被忽视。本组2男4女,年龄为28～41岁,于脑血管造影(颈动脉穿刺3例,经股动脉插管3例)后4～9小时内出现反复的TIA。临床主要表现意识障碍、偏瘫、失语、局限性癫痫等。脑CT扫描无阳性发现。即时给予脱水、血管扩张剂、神经细胞激活剂等药物治疗,均于72小时内恢复。究其原因可能为:(1)反复多次的动脉穿刺或多次高压注射造影剂,以致脑血管痉挛。(2)动脉穿刺后血栓形成或在动脉导管上血小板聚集和栓子形成的结果。(3)造影剂所致机体内环境的改变,包括血液粘稠度增加,红细胞聚集增加
Delayed CNS complications after cerebral angiography are often overlooked. The group of 2 males and 4 females, aged 28 to 41 years old, showed repeated TIA within 4 to 9 hours after cerebral angiography (carotid artery puncture in 3 and femoral artery intubation in 3). The main clinical manifestations of disturbance of consciousness, hemiplegia, aphasia, limitations of epilepsy. No positive brain CT scan was found. Immediately give dehydration, vasodilators, nerve cell activators and other drug treatment, were recovered within 72 hours. The reason may be: (1) repeated multiple arterial puncture or multiple high-pressure injection of contrast agents, resulting in cerebral vasospasm. (2) results of thrombus formation after arterial puncture or platelet aggregation and embolization on the patent ductus arteriosus. (3) changes in the environment caused by contrast medium, including increased blood viscosity, increased red blood cell aggregation
