椎-基动脉缺血发作与睡眠呼吸障碍
Objective To study the relationship between vertebro basilar ischemic attacks (VBI) and sleep related breathing disorders (SRBD). Methods Polysomnographic examinations were performed on 45 VBI patients. The incidence and characteristics of SRBD, and its relationship with various clinical factors were analyzed. Results Eighteen cases (40% ) were complicated with SRBD, among which 2/3 was obstructive and 1/3 was central types. They were correlated with obesity and prone to be suffered with cardiovascular disorders.Conclusions Brain stem dysfunction caused by long term repeated ischemias probably is the pathogenesis of SRBD, especially it' s central type, in VBI. The arrhythmia and hypertension secondary to SRBD may aggravate VBI. VBI and SRBD may be reciprocal and form a vicious circle which should draw attention in the prevention and treatment of SRBD in VBI. ``
