    Abstract:
    BACKGROUND: Aortic arch reobstruction is a common complication after aortic repair, with rates of reintervention varying from 0% to 40%, depending on the disease and the institution. This study aimed to determine the reintervention rate in children undergoing aortic arch repair using a tailored autologous pericardial patch at our center (Monroe Carell, Jr Children's Hospital at Vanderbilt, Nashville, TN). METHODS: This retrospective study examined all patients operated on by a single surgeon for aortic arch reconstruction through sternotomy, from 2011 to 2018, with 1 year of follow-up. Our data set was analyzed for normality by using the Shapiro-Wilk test, and nonparametric statistical methods were used. Kaplan-Meier survival analysis was performed, IBM SPSS software version 23 was used to perform all statistical analysis. RESULTS: A total of 171 patients met inclusion criteria. Twenty-three (13.5%) patients underwent aortic arch reinterventions during the study period, 17 (9.9%) catheter based and 3 (1.8%) surgical. Three patients (1.8%) had both. Freedom from reintervention at 1-year follow-up for the univentricular and biventricular patients was 82.1% and 89.4% (P = .174), respectively. To assess the growth of the aortic arch over time, cardiac catheterization measurements were used to index different parts of the aortic arch against the descending aorta. Ascending-to-descending aortic arch measurements revealed that the pre-Glenn median was 2.0 (interquartile range, 1.8 to 2.2), whereas the pre-Fontan median was 2.5 (interquartile range, 2.2 to 2.7) (P < .05). CONCLUSIONS: There was no significant difference in reintervention rates between biventricular and univentricular arches, and catheterization measurements showed significant growth of the arch over time. The use of a tailored autologous pericardial patch for aortic arch repair is comparable to other reported methods of arch repair.
