Acute Retrograde Ascending Aortic Dissection During Thoracic Endovascular Aortic Repair in a Rare Triple-Barreled Aortic Dissection

Outcomes of thoracic endovascular repair for type B aortic dissection with multichanneled morphology

“…6,7 According to previous studies, the incidence of MCAD varied from 4.9% to 9%. [5][6][7][13][14][15] We observed dissections with more than two adjacent FLs in 54 (8.4%) of 644 patients treated with TEVAR. This incidence was similar to that in previous reports, suggesting that the condition may occur frequently and is of great concern.…”

“…So far, most descriptions of MCAD have been limited to isolated case reports 5,[13][14][15] or studies evaluating poor outcomes and complications by open surgery and endovascular treatment. 6,7 According to previous studies, the incidence of MCAD varied from 4.9% to 9%.…”

“…The literature also indicates that the aortic wall may suffer from medial degeneration and cystic medial necrosis. 6,15 These factors may be the pathologic background for propagation of MCAD.…”

“…Apart from acute malperfusion and hemodynamic redistribution after TEVAR, endograft-related aortic wall injury may be another important risk factor for the adverse events, especially retrograde dissection. 22 Cheng et al 15 reported that a patient with triplechanneled AD developed retrograde type A AD during endograft repair.…”

Three-Channeled Aortic Dissection in a Patient without Marfan Syndrome

“…In contrast, a CT finding of an unbalanced area in the three channels has also been reported. [11][12][13] The significance and frequency of the differences between these two types of CT findings have not yet been elucidated. We speculate that the area of the three channels may be unbalanced in the acute period, but that the 3ch area may become balanced during the time course.…”
