Successful factors for improving aortic remodeling with thoracic endovascular repair and bare stent extension.
Objective: Proximal ExTension to Induce COmplete ATtachment (PETTICOAT), which uses downstream bare metal stents for structural support, demonstrates potential, yet its adoption is limited by variable outcomes. This study elucidates the potential of PETTICOAT in aortic dissection, emphasizing the determinants that guide patient selection.
Methods: A retrospective analysis of 60 patients who underwent full PETTICOAT for aortic dissections was conducted. A multivariate logistic regression model identified predictors of favorable aortic remodeling. Patients underwent standardized follow-up with computed tomography scans to assess size, volumetric changes, and anatomical conditions. Selection criteria included full PETTICOAT application and a minimum of 3 months of follow-up. Demographics, preoperative conditions, and procedural details were collected and analyzed.
Results: The analysis identified predictors of favorable aortic remodeling, including age >60 years, a larger downstream aorta stent graft, a smaller abdominal aorta (<450 mm2), and oral angiotensin II receptor blocker administration. Over a median 47.5 months of follow-up, survival rates in the favorable remodeling (97.3%) and unfavorable groups (100%) were similar. Downstream aortic event-free survival rates did not differ significantly (89.2% vs 73.9%), although the unfavorable group had a relatively higher incidence of distal stent-induced new entries (26.1% vs 8.1%).
Conclusions: The PETTICOAT concept effectively enhances aortic remodeling in complex aortic dissections. Predictors for favorable remodeling, including age, stent graft sizing, aortic diameter, and angiotensin II receptor blocker therapy, offer insights for optimizing patient selection. This approach improves survival outcomes, mitigates risks associated with untreated aortic segments, and provides a minimally invasive solution for aortic dissections. Despite some outcome variations, the technique holds promise for addressing the challenges of aortic dissections, with the potential for further refinement in patient selection and technique application.
期刊介绍:
Journal of Vascular Surgery ® aims to be the premier international journal of medical, endovascular and surgical care of vascular diseases. It is dedicated to the science and art of vascular surgery and aims to improve the management of patients with vascular diseases by publishing relevant papers that report important medical advances, test new hypotheses, and address current controversies. To acheive this goal, the Journal will publish original clinical and laboratory studies, and reports and papers that comment on the social, economic, ethical, legal, and political factors, which relate to these aims. As the official publication of The Society for Vascular Surgery, the Journal will publish, after peer review, selected papers presented at the annual meeting of this organization and affiliated vascular societies, as well as original articles from members and non-members.
