Severe migraine associated with coarctation of aorta: complete recovery following balloon dilation.

We report on a rare association of severe migraine headaches associated with coarctation of aorta that completely resolved following dilation of the constricted aorta. A 6-year-old girl presented with severe pounding headaches accompanied with recurrent vomiting, associated with photophobia and phonophobia. She experienced frequent awakenings with severe headaches and vomiting. The described excruciating, prolonged, and practically persistent headaches were not relieved by analgesics and ergotamines. Neurologic assessment and brain computed tomography were both normal. A systolic murmur at the third right intercostal space prompted a cardiac echocardiogram, which demonstrated coarctation of the ascending aorta beyond the orifice of the left common carotid artery. Catheterization revealed a systolic gradient of 54 mm Hg, and the constricted lumen of the aorta was then dilated by a balloon. The excruciating vascular headaches and associated symptoms had abated instantaneously following this procedure. To the best of our knowledge, this is the first report associating severe migraine headaches in a child with coarctation of the aorta. Given complete recovery following balloon dilation of the aorta, cardiac echocardiogram should be added to the diagnostic battery of children with severe unresponsive migraine.
