Bavaria JE, Brinkman WT, Hughes GC, et al. - For acute complicated type B aortic dissections, standard of care involves thoracic endovascular aortic repair, researchers here investigated the long-term single-device outcomes. This prospective, nonrandomized Dissection Trial was done including 50 patients treated with the Valiant Captivia thoracic stent graft (Medtronic Inc, Santa Rosa, Calif) for acute complicated type B aortic dissections. At 5 years, compliance for both clinical and imaging follow-up was 78% (18 out of 23) for the available patients. Notable characteristics at baseline were malperfusion in 86% of patients (43 out of 50), ruptures in 20% (10 out of 50), and DeBakey class IIIB dissections in 94% (46 out of 49). The 5-year freedom from dissection-related mortality, secondary procedures related to the dissection, and endoleaks was 83%, 86%, and 85%, respectively. After 5 years, a completely thrombosed false lumen in the stented segment of the aorta was reported in 89% of patients (16 out of 18) and the true lumen diameter over the length of stent graft was stable or elevated in 94% of patients (16 out of 17) while 77% (13 out of 17) had stable or reduced false lumen diameter after 5 years.
