Abstract
OBJECTIVE: Adenoid hypertrophy causing upper airway obstruction can cause cardiovascular complications, including pulmonary hypertension and right heart failure in children. Adenoidal-nasopharyngeal ratio (ANR) is a practical, non-invasive and reliable method to evaluate adenoid enlargement. Our aim was to evaluate a possible association between ANR and echocardiographic parameters of right ventricle. METHODS: Twenty-one children who were affected by upper respiratory obstruction symptoms due to adenoid hypertrophy were included in this study (male/female: 12/9; mean age was 6.0 +/- 1.5 years). ANRs were calculated as the ratio of adenoidal depths to the nasopharyngeal depths on lateral cephalometric radiographs. Pulmonary arterial pressures, right ventricular diastolic filling parameters (peak E, peak A, E/A ratio), right ventricular end-diastolic diameters, and left ventricular ejection fractions were measured using echocardiography both preoperatively and also 3 months after the operation. RESULTS: Preoperative pulmonary arterial pressure, E/A ratio, right ventricular end-diastolic diameter, and left ventricular ejection fraction values were 23.10 +/-3.43 mmHg, 1.01 +/- 0.20, 1.95 +/- 0.16 cm, and 69.43 +/- 3.68%, respectively. Postoperative pulmonary arterial pressure, E/A ratio, right ventricular end-diastolic diameter, and left ventricular ejection fraction values were 16.94 +/- 1.45 mmHg, 1.24 +/- 0.14, 1.72 +/- 0.15 cm, and 69.77 +/- 2.17%, respectively. There were significant differences between preoperative and postoperative pulmonary arterial pressures, E/A ratios, and right ventricular end-diastolic diameters (p < 0.01 for each), while left ventricular ejection fraction values did not significantly change after the operation (p > 0.05). There was a negative correlation between E/A ratio and ANR-Ba (p < 0.05, r = -0.44). CONCLUSION: ANR can give information about the right ventricular functions in children with enlarged adenoids causing obstructive symptoms.
