目的:探讨良性阵发性位置性眩晕(BPPV)的复发原因及临床意义。方法:回顾性分析65例耳石复位法治疗成功后2年内未复发的BPPV及44例耳石复位法治疗成功后2年内复发的BPPV的临床资料、经颅多普勒(TCD)、头颅CT或MRI检查结果。结果:BPPV预后与年龄、偏头痛病史、颅内及颈部动脉狭窄、脑卒中史密切相关。结论:BPPV复发病因较多,但大部分均与不同原因所造成的迷路血液供应障碍相关。了解其复发原因可从患者临床资料、TCD、头颅CT或MRI检查结果对BPPV的复发作一预测,并可针对性作相应干预。
Objective: To investigate the recurrence and clinical significance of benign paroxysmal positional vertigo (BPPV). Methods: The clinical data of BPPV recurrence within 2 years after the success of otolith restoration in 44 patients with otolith recovery within 2 years after retrospective analysis were retrospectively analyzed. The clinical data of transcranial Doppler (TCD), cranial CT Or MRI examination results. Results: The prognosis of BPPV was closely related to age, migraine history, intracranial and cervical artery stenosis and stroke. Conclusion: The causes of BPPV recurrence are more, but most of them are related to obstructed blood supply disorders caused by different reasons. To understand the reasons for the recurrence of patients with clinical data, TCD, CT or head CT examination of the recurrence of BPPV make a prediction, and can be targeted for appropriate intervention.
