Endovascular Repair of Acute and Chronic Aortic Type B Dissections: Main Factors Affecting Aortic Remodeling and Clinical Outcome

Abstract

The aim of this study was to assess factors influencing the clinical outcome and morphological changes of acute and chronic type B aortic dissection after thoracic endovascular aortic repair (TEVAR). Aortic remodeling after TEVAR may be associated with clinical outcome, complications, and endoleak development. Sixty cases of TEVAR for complicated type B acute aortic dissection (AAD) (n = 29) and chronic aortic dissection (CAD) (n = 31) with a minimum follow-up of 3 years were retrospectively reviewed. Using computed tomography images, we assessed true lumen, false lumen, and total aortic short-axis diameters. Six procedural factors were analyzed in relation to aortic remodeling and other outcomes. Analysis of variance was used to compare short-axis, false lumen, and true lumen diameters during the follow-up period. Univariate and multivariate analyses were used to assess the relationship between procedural factors and multiple outcomes. A total of 100 stent grafts were implanted in 60 consecutive patients with acute aortic dissection (AAD) and CAD. Aortic remodeling consisting of false lumen thrombosis and shrinkage was more prominent in AAD than in CAD, especially within the first 18 months. Of note, the entire aortic diameter...Continue Reading

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
