Dear editor, The study published by Tang et al., entitled “Factors Affecting False Lumen Thrombosis in Type B Aortic Dissection,” highlighted the influence of morphological aspects of type B aortic dissection (TBAD), according to the Stanford classification, on false lumen thrombosis prior to treatment with endovascular repair of the thoracic aorta. It has been shown that false lumen thrombosis occurs significantly less frequently in patients with TBAD and renal failure, when compared with those with TBAD and normal renal function. […]

Abstract Background Complete thrombosis of the false lumen facilitates remodeling of type B aortic dissection (TBAD). Morphological characteristics affect thrombosis in the false lumen. Objectives Discuss the factors present before admission that influence false lumen thrombosis in patients with TBAD. Methods We studied 282 patients diagnosed with TBAD in our hospital between January 2008 and December 2017. We divided the subjects into a thrombotic group and a non-thrombotic group based on whether any thrombus was detectable in the false lumen. […]
