[Lesion of intractable hiccups due to medullary infarction].Rinsho Shinkeigaku. 2014; 54(5):403-7.RS
The frequency and clinical characteristics of intractable hiccups due to the medullary infarction is unknown. The aim of this study was to identify the lesions of hiccups using by brain MRI. Ninety acute medullary patients admitted to our stroke center within 14 days of stroke onset between April 2004 and August 2012 were retrospectively studied. We evaluated clinical characteristics and the frequency of the patients causing intractable hiccups among acute medullary stroke patients. We divided the patients into two groups, intractable hiccups group, and not hiccups group. Of 90 patients, five (5.5%) had intractable hiccups. Hiccups group had more frequently involved right middle medullary lesion than not hiccups group (hiccups group vs. not hiccups group; (60% vs. 4%, p < 0.001). In 16 cases reported the lesion of intractable hiccups, the right middle medullary lesion was 11 cases. We suspected that the lesion of the intractable hiccups was associated with the right middle medullary.
