Notes.
I. This classification is based on the Draft Classification of Cerebrovascular Diseases (1986), the Classification of Cerebrovascular Diseases (Recommendations of the First Hospital of Zhongshan Medical University, 1993), and the Classification of Cerebrovascular Diseases (1993).
I. This classification is based on the Draft Classification of Cerebrovascular Diseases (1986), the Classification of Cerebrovascular Diseases (Recommended by the First Hospital of Zhongshan Medical University, 1993), the Outline of Classification of Cerebrovascular Diseases (Recommended by Huashan Hospital of Shanghai Medical University, 1993), and the opinions of the delegates of the Fourth National Conference on Cerebrovascular Diseases (Chengdu).
In June 1996, all members of the Chinese Society of Neurosurgery discussed and supplemented the draft, and some experts of the leading group of cerebrovascular disease prevention and treatment research organized by the National Office of Cerebrovascular Disease Prevention and Control discussed it,
The revision was proposed by the National Office of Cerebrovascular Disease Prevention and Control. Finally, the classification of cerebrovascular diseases (1995) was synthesized.
The classification can be divided into transient ischemic attack, reversible ischemic neurological deficit (symptoms disappear within 3 weeks after onset), progressive stroke, and complete stroke according to the course of the disease. Only transient ischemic attacks are included in this classification,
Others are not included.
The numbers in parentheses refer to the World Health Organization International Classification of Diseases, 10th Revision.
D. The term “asymptomatic infarction” was added to meet the needs of the increasing use of imaging.
V. “Cerebral blood supply deficiency” and “cerebral arteriosclerosis” (440) have been removed from the classification.
(6) The “mixed stroke” proposed in China needs further study, so it is not included in this classification for the time being. (Chinese Society of Neurology Chinese Society of Neurosurgery)
