| Abstract |
|
A severe or prolonged drop in blood pressure caused by syncope can lead to border-zone infarction in the absence of coexisting large artery disease. Syncope due to defecation represent special cases of reflex syncope for which the mechanisms are poorly understood and probably multifactorial. We experienced a 56-year-old woman was recurrent loss of consciousness duration defecation. Brain MRI revealed multifocal high signals in T2WI and FLAIR image on both end-artery border zone, but brain MRA revealed normal finding. Thus, We report a rare case of an old woman patient with end-artery border zone infarction due to prolonged hypoperfusion that was caused by defecation syncope. |
