Clinical features of cryptogenic stroke accompanied with patent foramen ovale / 临床神经病学杂志

ABSTRACT

Objective To investigate the clinical features of cryptogenic stroke accompanied with patent foramen ovale ( PFO) .Methods The clinical data of 8 cryptogenic stroke patients accompanied with PFO were analyzed retrospectively.Results Eight patients aged 15-55 years old, average age was 39.75 years old.They were acute onset.The clinical symptoms were limb weakness in 5 cases, speech disorder in 2 cases, walking instability, weakness of lower limbs, epilepsy, acmesthesia decrement of one side in 1 case retrospectively. Doppler echocardiography showed PFO was in all the patients.Brain MRI showed frontal lobe, parietal lobe, temporal lobe, occipital lobe, insular cortex, periventricular body, hind limb of the internal capsule, basal ganglia, cerebellum had low T1 single, and high T2 single.Four cases were unilateral involvement, and 4 cases were bilateral involvement;6 cases were multiple lesions, 2 cases were single lesion;involved in anterior circun systemlatio system was in 4 cases, involved in posterior circulation system was in 1 case, and involved in anterior and posterior circulation system was in 3 cases.All cases had no recurrence after treatment.Conclusions The onset age of cryptogenic stroke patients accompanied with PFO is relatively young.Brain MRI shows multiple lesions, it can involed in bilateral, anterior and posterior circulation system.Prognosis of cryptogenic strok accompanied with PFO is good.
