我们描述了 1982 年至 1988 年 7 月从基于人群的卒中登记处收集的 43 名外侧髓样梗死 (LMI) 患者的急性和长期预后。平均年龄为 63.9 岁，中位随访时间为 33 个月。在急性期，5名患者（11.6%）死于呼吸和心血管并发症，并发生2例新的卒中，均发生在后循环。在随访期间，仅 2 名患者复发椎基底动脉区卒中（每年发生率为 1.9%）。中风的机制是椎动脉（VA）分支闭塞，导致内侧髓质综合征，以及基底动脉血栓形成从对侧远端 VA 狭窄传播。在LMI的急性期，呼吸和心血管事件（可能是由与外侧髓质病变相关的自主神经功能障碍引起）是主要危害。随访期间复发性后循环卒中并不常见。
We describe the acute and long-term prognosis in 43 patients with lateral medullary infarction (LMI) collected from a population-based stroke registry from 1982 to July 1988. Mean age was 63.9 years and median time of follow-up was 33 months. In the acute phase, 5 patients (11.6%) died from respiratory and cardiovascular complications and 2 new strokes occurred, both in the posterior circulation. During follow-up, recurrent vertebrobasilar territory strokes occurred in only 2 patients (a rate of 1.9% per year). The mechanisms of stroke were vertebral artery (VA) branch occlusion, causing a medial medullary syndrome, and basilar artery thrombosis propagating from a contralateral, distal VA stenosis. In the acute phase of LMI, respiratory and cardiovascular events, presumably caused by autonomic dysfunction related to the lateral medullary lesion, are the major hazards. Recurrent posterior circulation strokes were uncommon during follow-up.
