Objective:To investigate the clinical types and characteristics of cerebral watershed infarcts (CWI). Methods Analysis of the clinical data and imaging characteristics of 192 cases with CWI confirmed by CT scan or MBI. Results In 69 cases (35.9%), CWI appeared as wedge-shaped areas on CT scan or MRI, the infarcts located at marginal zones between the anterior and middle cerebral arteries and were usually associated clinically with hemiparesis, transcortical motor aphasia and dementia. In 74 cases(38. 5%) the...

Objective:To investigate the clinical types and characteristics of cerebral watershed infarcts (CWI). Methods Analysis of the clinical data and imaging characteristics of 192 cases with CWI confirmed by CT scan or MBI. Results In 69 cases (35.9%), CWI appeared as wedge-shaped areas on CT scan or MRI, the infarcts located at marginal zones between the anterior and middle cerebral arteries and were usually associated clinically with hemiparesis, transcortical motor aphasia and dementia. In 74 cases(38. 5%) the infarcts also appeared as wedge-shaped areas on CT scan and MRI, but located at marginal zones between the middle and posterior cerebral arteries, the patients mainly showed mild hemiparesis and apathy. In49 cases (25.5%), the long-line or triangle-shaped infarct areas usually located at marginal zones between the superficial and deep territory of the middle cerebral arteries in the basal ganglia and posterolateral angulus frontalis The presentation of CWI is complicated, and the diagnosis of that mainly depends on imaging studies such as CT scan and MRI.

目的 探讨脑分水岭梗死(CWI)的类型和临床特点。方法 分析192例经CT或磁共振成像(MRI)证实的CWI临床资料及影像学改变。结果 皮层前型69例,占35.9%,病灶在大脑前动脉和大脑中动脉边缘区,呈楔形。临床表现偏瘫、经皮层运动性失语、智能减退等症状。皮层后型74例,占38.5%,病灶在大脑中动脉和大脑后动脉边缘区,呈楔形,临床以轻偏瘫、情感淡漠为主要表现。皮层下型49例,占25.5%,病灶在大脑中动脉皮层支与深穿支的边缘带,常位于额角后外方和基底节区,呈长条状、三角形。结论 CWI的临床表现复杂,诊断主要依据CT或MRI。

Objective To investigate the relationship between cerebral watershed infarction(CWI) and intracranial and extracranial arterial stenosis.Methods Data were collected on 688 patients with cerebral infarction admitted from Jan.2001 to Dec.2002 ,All patients were examined by CT and (or) MRI to determine the infarction position.The intracranial and extracranial arteries were examined by Duplex, severe arterial stenosis were examined by DSA for further comfimation.Results There are 139 cases of cerebral watershed infarction among them.There were 51 cases of internal carotid artery occlusion, 44 cases of severe internal carotid artery stenosis and 60 cases of multi intracranial artery stenosis in 549 cases of non- cerebral watershed infarction.There were 20 cases of internal carotid artery occlusion, 17 cases of severe internal carotid artery stenosis and 134 cases of multi intracranial artery stenosis. There was significant difference between the two groups by chi-square test.Conclusions The main factors of cerebral watershed infarction are internal carotid artery occlusion and severe stenosis and multi intracranial artery stenosis.
