URRUTIA-TORRES, Francisco et al. Patent foramen ovale in pediatric patients with migraine. Bol. Med. Hosp. Infant. Mex. [online]. 2006, vol.63, n.6, pp.389-394. ISSN 1665-1146.

Introduction. Because the patency of foramen ovale in adult patients with migraine has been detected to have association with vascular events, we think it is of great importance to detect this cardiovascular anomaly in children with the diagnosis of migraine and prevent secondary complications. Objective: Determine the prevalence of patent foramen ovale in pediatric patients with migraine. Material and methods. Children diagnosed with migraine (with or without aura) according to the criteria of the International Headache Society seen during the period between November 2005 and June 2006 in the Department of Pediatric Neurology at the Hospital Infantil de Mexico Federico Gomez were enrolled and a bidimensional Doppler echocardiogram was performed looking for the persistence of foramen ovale. Results. We included 40 patients with ages ranging between 5 to 17 years, 57% were girls and 42% presented migraine with aura. Based on the time of evolution our study group was stratified as follows: 16% less than a year, 35% 1 year, 25% 2 years, 17% 3 years and 7% 5 years. We found no association between gender and a specific type of migraine. We found patency of foramen ovale in 11 patients (27.5%), 5 females and 6 males; 9 (81.8%) patients presented migraine with aura and 2 (18.1%) without aura. Conclusion. We found a high prevalence of patent foramen ovale in patients with migraine with aura. From 17 patients in our study group with diagnosis of migraine with aura; 9 of them (52%) had ultrasonographic finding of patency of the foramen.
