PURPOSE: We investigated the relationship between aortic remodeling and timing of thoracic endovascular aortic repair( TEVAR) in patients with uncomplicated Stanford type B aortic dissection.
METHODS: 29 patients with sub-acute and early chronic uncomplicated Stanford type B aortic dissection underwent TEVAR between February 2019 and August 2022 in our hospital. We retrospectively compared aortic remodeling between 19 patients in the sub-acute( SA) group( 15-90 days from onset) and 10 patients in the early chronic( ECh) group( 91-365 days from onset) using the false luminal area reduction rate using computed tomography imagings.
RESULTS: The false lumen area reduction rates at the level of the carina in the SA and ECh groups were 21.9±13.5% and 7.0±21.2% (p=0.04) around 3-8 days after TEVAR, 91.8±13.8% and 62.6±48.4 % (p=0.26) at 6 months, 96.6±7.2% and 68.7±42.5% (p=0.14) at 12 months, and 96.2±10.0% and 79.2±37.6% (p=0.62) at 18 months respectively. There were no significant differences between the two groups regarding any complication.
CONCLUSION: Preemptive TEVAR for sub-acute and early chronic uncomplicated Stanford type B aortic dissection resulted in good remodeling and it may provide a good prognosis, especially in the subacute stage.
