“…10 There is limited literature published on the incidence and risk factors for migration of stent graft after TEVAR. The incidence of migration was found to be 19.3% (6/31) in our study, which is higher than a few of the previously published data 5,[11][12][13][14][15] ; however, it is consistent with the study done by Nasr et al 16 Proximal landing zone 3 was a risk factor for stent-graft migration in our study, while zone 2 was a protective factor for migration. Although none of the combinations as per MALAN classification showed a significant association, the OR showed an increasing trend for migration toward I/3 and II/3.…”

Background Migration of the stent-graft post-thoracic endovascular aortic repair (TEVAR) is not uncommon; however, it is sparsely reported. The objective of this study was to assess the incidence, risk factors, and complications of stent-graft migration post-TEVAR. Materials and Methods Thirty-one patients who underwent TEVAR were retrospectively analyzed. The demographic, anatomical, and procedure-related factors were assessed. The measurements were done along the greater curvature of aorta around two fixed anatomic landmarks, that is, left common carotid artery or neoinnominate artery (hybrid repair) proximally and celiac artery distally. Aortic elongation and migration at proximal, distal, as well as at overlapping zone were measured. More than 10 mm of migration was considered significant. Results Significant migration was observed in six (19%) patients. No significant migration was observed in the overlapping zone. The proximal landing zone 3 (odds ratio [OR] 12.78, p 0.01) was a significant risk factor, whereas landing zone 2 was a protective factor against the migration (OR 0.08, p 0.02). The odds for migration were more in segments I/3 and II/3 compared with I/2 and II/2, respectively, as per Modified Arch Landing Areas Nomenclature. A single complication was seen in the migration group which was treated by an overlapping stent graft. Conclusion The stent-graft migration after TEVAR is not uncommon. Type 3 proximal landing zone was a significant risk factor for migration with an increased risk toward I/3 and II/3. Proximal landing zone 2 as well as adequate overlapping distance in multiple stent grafts can prevent migration. Ethical Approval No IECPG-227/24.06.2020

“…Thoracic endovascular aortic repair (TEVAR) has expanded with thoracic aortic pathology. Successful TEVAR depends notably on proximal and distal stent-graft fixation zones (Nasr et al 2019). However, the long-term consequences of the device implantation on the native aortic anatomy are not fully mastered (Roos et al 2016).…”
