Vertebral Artery Dissection in a Patient With Wildervanck Syndrome

Vertebral artery dissection as a cause of stroke is rarely reported in children. The association between vertebral artery dissection and Klippel-Feil syndrome is also very rare. We report on a case of vertebral artery dissection with posterior circulation involvement in a child with Klippel-Feil syndrome after a hard physical-training lesson. She was also diagnosed with Wildervanck syndrome, with additional clinical findings. Vertebral artery dissection should be considered in patients with Klippel-Feil syndrome who present with acute-onset neurologic signs. Movements such as hyperextension with rotation of the neck should be avoided in these cases.
