Vertebral artery (VA) dissection is one major cause of brain infarction in young and middle-aged adults. Risk factors for VA dissection are hypertension, diabetes mellitus, hyperlipidemia, trauma, and genetic factors. A 32-year-old man with familial Hirschsprung disease at the age of 2 presented cerebellar ischemic stroke due to bilateral VA dissections. A stroke recurred within 17 days despite oral dual antiplatelet therapy. Bilateral VA dissections and recurrent dissections are related to genetic mutations associated with connective tissue diseases. A part of familial Hirschsprung disease has genetic factors in common with cerebrovascular disease. There may be a common genetic background between his VA dissection and Hirschsprung disease.
