作者报导76例短暂性脑缺血发作(TIA),45例延迟性短暂性脑缺血发作(PTIA),85例小中风(又称部分性非进展性脑卒中、PNS)的自然病史和随访5～7年的研究结果,并对此进行了比较评价。由于 TIA 和 PTIA 最终均能完全恢复,作者将它们统称为可逆性缺血发作(RIA)。在206例中男性136例(66%),女性70例(34%)。颈动脉受累较椎—基动脉受累常见(145例:53例)。颈动脉受累的特点是:(1)PTIA 的发病较 TIA 和 PNS 缓慢;(2)PNS 的运动障碍常以一侧为主,而 TIA 和 PTIA 常只累及一个肢体;(3)TIA 常有失语;(4)1/4PNS 病人有单侧感觉迟钝。椎—基动脉受累的特点是:(1)绝大多数的发作是突然的;(2)运动障碍常见于一侧,PNS 特别多见波及面肌、眼球运动系统及Ⅸ、Ⅹ、Ⅺ、Ⅻ颅神经;(3)也可见共济失调、视觉障碍、构音困难和感觉障碍等,而约半数的 TIA 病人有两侧对称性黑 The authors reported the natural history and follow-up of 76 patients with transient ischemic attack (TIA), 45 patients with delayed transient ischemic attack (PTIA), 85 patients with minor stroke (also known as partial nonstrusive stroke, PNS) 5 to 7 years of research results, and conducted a comparative evaluation. Since both TIA and PTIA eventually recover completely, the authors collectively refer to them as reversible ischemic attacks (RIA). Of the 206 patients, 136 were male (66%) and 70 were female (34%). Carotid involvement than vertebral-based artery involvement is common (145 cases: 53 cases). Carotid involvement is characterized by: (1) the incidence of PTIA is slower than that of TIA and PNS; (2) dyskinesias of PNS are often dominated by one side, while TIA and PTIA often involve only one limb; (3) TIA often has aphasia ; (4) 1 / 4PNS patients unilateral unresponsive. Vertebrobasilar involvement is characterized by (1) the vast majority of attacks are abrupt; (2) dyskinesia is common on one side and PNS is particularly common in facial muscles, eye movement systems and Ⅸ, Ⅹ, Ⅺ, Ⅻ Cranial nerves; (3) ataxia, visual disturbances, dysarthria and sensory disturbances can also be seen, while about half of TIA patients have bilateral symmetry black
