“…Following TEVAR, the false lumen in this patient gradually underwent complete thrombosis, the maximal descending aortic diameter decreased, and the size and diameter of the true lumen in both the graft and distal regions increased, consistent with the work of Chung et al [ 2 ]. For patients with symptomatic aortic dissection with true lumen collapse, endovascular fenestration of the dissection flap and/or expansion of the true lumen with a large-diameter balloon can be used to increase the perfusion of the true lumen, as demonstrated in previously published case reports[ 10 , 11 ].…”

BACKGROUND In the context of aortic dissection, increasing pressure within the newly formed false lumen can result in the progressive compression of the true aortic channel. However, true lumen collapse in chronic type B aortic dissection (cTBAD) patients is rare, with few clinical or experimental studies to date having explored the causes of such collapse. CASE SUMMARY In the present report, we describe a rare case of true-lumen collapse in an 83-year-old patient diagnosed with cTBAD, and we discuss potential therapeutic interventions for such cases. Following thoracic endovascular aortic repair (TEVAR), computed tomography angiography revealed satisfactory stent-graft positioning, no endoleakage, true lumen enlargement, thrombus formation in the false lumen, and slight enlargement of the true lumen distal to the stent-graft. Computational hemodynamic analyses indicated that the wall shear stress and pressure within the false lumen were significantly reduced following TEVAR. CONCLUSION TEVAR treatment of cTBAD patients suffering from proximal true lumen collapse can facilitate some degree of effective remodeling.
