| Abstract: | ObjectiveUsing a national data set, we sought to describe the population of patients and the nature and timing of reinterventions after thoracic endovascular aortic repair (TEVAR) by aortic disease as well as their impact on survival.MethodsWe evaluated the national data set for TEVAR in the Vascular Quality Initiative from 2010 to 2017. Student t-test and χ2 analysis were used to compare continuous and categorical variables in the reintervention and no reintervention groups, respectively. Freedom from reintervention and survival analysis was performed using Kaplan-Meier methods.ResultsA total of 7006 patients were evaluated: 51.2% thoracic aortic aneurysm, 33.5% type B dissection (TBD), 7.0% penetrating aortic ulcer, 6.7% trauma, and 1.6% intramural hematoma. Overall, 553 patients (7.9%) underwent at least one reintervention, with an in-hospital reintervention rate of 3.5%. Reinterventions were most commonly performed for TBD (11.5%), with reinterventions for other diseases occurring at lower rates: thoracic aortic aneurysm, 6.7%; intramural hematoma, 5.4%; penetrating aortic ulcer, 4.8%; and trauma, 1.8%. The most common cause of reintervention across all aortic diseases was type I endoleak. The most common long-term reinterventions were placement of endovascular stent graft (65%), other surgical treatments (15.9%), other endovascular treatment (13%), endovascular branch treatment (12.4%), surgical treatment with no device removal (11.0%), and surgical branch treatment (10.4%). Freedom from reintervention was decreased for TBD compared with other diseases (P < .001). There was no difference in survival comparing patients undergoing reinterventions and those without (P = .87). However, patients undergoing in-hospital reintervention trended toward increased mortality (P = .075).ConclusionsWhereas reinterventions were not rare after TEVAR, there was no difference in mortality between patients undergoing reintervention and those without. Patients undergoing TEVAR for TBD demonstrated the highest reintervention rate. This study highlights the importance of long-term follow-up to address disease-specific patterns of reintervention. |
