Background Thoracic aortic dissection (AD) is a rare occurrence in childhood and mostly associated with connective tissue disorders or congenital abnormalities. We examined the characteristics associated with AD and predictors of survival. Methods The Kids' Inpatient Database (1997-2009) was used to identify thoracic ADs occurring in patients <20-y-old. Clinical characteristics, as well as determinants of survival, were analyzed using standard statistical methods. Results One hundred sixty-eight cases of thoracic AD were identified during the study period. Overall survival was 83%. Average length of stay was 15.9 ± 16.9 d, with charges 181,867.92 ± $211,985.00. Thoracic dissection tended to affect adolescents aged 15-19 y (67%), males (76%), and Caucasians (56%) most frequently. Most patients were privately insured (64%) and treated at urban teaching centers (86%). Commonly associated diagnoses were hypertension (18%), Marfan syndrome (15%), and aortic valve disorders (8%). When repair was performed, open repair was more frequent (88%) than endovascular repair (6%). Hemorrhage was the most common complication (19%). Multiple determinants of survival were found. Girls (mortality odds ratio: 0.21 [0.05-0.91]) fared better than boys, P = 0.023. Patients with Medicaid (2.84 [1.21-6.69]) had higher mortality versus privately insured, P = 0.014. Income, race, and hospital characteristics, and type of repair were not significant predictors, even on sub-analyses of surgical and nonsurgical groups separately. Conclusions Dissection of the thoracic aorta is a rare but significant condition affecting the pediatric population. Most repairs are performed using open technique. Payer status and gender are predictors of survival in these cases.
