脑血栓的复发与多种因素有关。由于无症状性脑梗塞的存在,可区分为症状学复发与神经放射学复发。作者以初次发作22日后复发的脑血栓为对象,以神经放射学为主研究了临床所见。根据复发时的临床症状将复发分为3型:与首次发作有不同症状的并发型,初发神经症状进展、加重的进展型和兼具以上两型特点的混合型。22例复发脑血栓症中,并发型12例,进展型6例,混合型4例。并发型中多数病例表现为对侧又出现偏瘫和台并假性球麻痹。复发期间4个月～9年,平均4.7±3.0年。影像所见主要是与首次发作不同部位的病灶。进展型表现为不全偏瘫和视力障碍,早期加重。影像所见为大脑后动脉供应区梗塞向对侧进展或大脑中动脉供应区的白质病变扩大。但位于左侧
Recurrence of cerebral thrombosis and a variety of factors. Because of the existence of asymptomatic cerebral infarction, can be divided into symptomatic relapse and neuroradiology recurrence. The author of the first episode of 22 days after the recurrence of cerebral thrombosis as the object, mainly to study the clinical findings of neuroradiology. According to the clinical symptoms of relapse will be divided into three types of recurrence: with the first attack with different symptoms of concurrent type, the initial onset of neurological symptoms, aggravating progressive and both types of mixed characteristics. In 22 cases of recurrent cerebral thrombosis, there were 12 concurrent cases, 6 progressive cases and 4 mixed cases. Most cases of concurrent type showed contralateral hemiplegia and Taiwan and pseudobulbar paralysis. The recurrence period of 4 months to 9 years, an average of 4.7 ± 3.0 years. The image is mainly seen with lesions of different parts of the first attack. Progressive performance of incomplete hemiplegia and visual impairment, early increase. The image shows an enlargement of infarction in the posterior cerebral artery supplying area to the contralateral side or white matter lesions in the middle cerebral artery supply area.
