Objective This article aims to investigate the incidence rate of retrograde type A aortic dissection (RTAD) and risk factors RTAD in relation thoracic endovascular repair (TEVAR). Methods Patients with disease who underwent TEVAR at Henan Provincial People's Hospital from January 2004 December 2019 were enrolled present research. The associated following using univariate multiple logistic regression analyses. Results During study period, total 1,688 patients included this study, these, 1,592 cases B (TBAD) group, 96 non-TBAD group. There 1,230 362 intramural hematoma and/or penetrating ulcer TBAD group 68 aneurysm, 21 pseudoaneurysm, seven congenital coarctation. overall was 1.1% (18/1,688) patients, all which occurred cohort comprised 18 an average age 56.78, consisting 13 males 5 females. Among them, individuals exhibited hypertension. Ten instances happened within perioperative including two during surgery, six three months, after one year, longest interval 72 months TEVAR. successfully implemented 17 while operation technique temporarily altered case. new entry position for identified as proximal region stent graft (SG) five cases, site more than 2 cm away SG. greater curvature aorta, case lesser curvature. Multivariate analysis revealed that SG oversizing ratio is a relevant factor RTAD. However, ascending diameter, arch type, anchored not directly related occurrence Conclusion rare yet catastrophic complication. It could occur both procedure, early late postoperative periods.
