Although adenotonsillar hypertrophy is a well-recognized disease since the beginning, it was not described to be cause of pulmonary hypertension until 1965 by Menashe and Ferrehi. There are only few records in the literature, analyzing the existence of pulmonary hypertension in children with obstructive adenotonsillar hypertrophy. AIM: The aim of this study was to evaluate the prevalence of pulmonary hypertension in children with obstructive adenotonsillar hypertrophy. STUDY DESIGN: Transversal cohorte. MATERIAL AND METHOD: Fourteen patients with indication for adenotonsillectomy, from both sexs, with age ranging from O to 15 years, were analyzed in this study. AlI patients underwent to a complete pre-surgery evaluation, with questionary, complete ENT evaluation, lateral X ray films, nasofibrolaryngoscopy and echocardiography. RESULTS: From all fourteen patients analyzed, one (7,14%) had pulmonary hypertension in the echocardiography examination. CONCLUSION: Adenotonsillar hypertrophy is a cause of pulmonary hypertension, and echocardiography examination is a very usefull exam to determine to presence of the pathology. Adenotonsillectomy may revert pulmonary hypertension in children with adenotonsillar hypertrophy.
