Purpose : The aim of this study was to evaluate the aortic growth rate and the factors influencing aneurysmal dilatation after uncomplicated acute type B aortic dissection (UTBAD).
Methods : We conducted a retrospective review of medically treated patients with UTBAD between September 2004 and January 2020. Total of 105 patients who underwent more than two serial computed tomography were enrolled this study and follow-up was 47.8 ± 43.9 months. The followings were excluded: (1) unclear onset, (2) initial aortic diameter >55mm, (3) completely thrombosed false lumen, (4) traumatic or iatrogenic dissection, (5) confined to abdominal aorta, (6) combined with congenital anatomical variation.
Results : The overall growth rate of proximal descending aorta (pDTA), mid DTA (mDTA), distal DTA (dDTA), abdominal aorta (AA), maximal DTA (maxDTA) and maximal AA (maxAA) was 0.62±1.9, 2.9±5.2, 2.1±4.0, 1.2±2.2, 3.3±5.6, 1.4±2.5 mm/yr, respectively. The growth rate was higher at early stage, and gradually decreased; growth rate of pDTA, mDTA, dDTA, AA, maxDTA, maxAA for less than 3 months after dissection was 1.3±9.6, 12.6±18.2, 7.6±11.7, 5.9±7.5, 16.7±19.8, 6.8±8.9 mm/yr, whereas for more than 2 years was 0.2±0.6, 1.6±1.6, 1.2±1.3, 0.9±1.4, 1.7±1.9, 1.2±1.7 mm/yr, respectively. The following predictors of aneurysmal dilatation were identified: older age, elliptical true lumen, and large proximal entry tear > 10mm on initial imaging.
Conclusion : Aortic growth rate was higher at early stage after UTBAD, and gradually decreased. Older patients with elliptical true lumen, and large proximal entry tear on initial imaging might benefit from early endovascular intervention.
