Stanford Type A Aortic Dissection After Cheatham–Platinum Stent Insertion for Aortic Coarctation: A Case Report

Background: Coarctation of the aorta (CoA) stenting can lead to late vascular complications, but Stanford type A aortic dissection years after Cheatham–Platinum (CP) stent implantation is exceptionally rare. We report a successfully managed case to discuss an effective surgical approach. Case: A 16-year-old female presented with sudden loss of consciousness caused by a substantial pericardial effusion. Seven years prior, she had undergone CP stent implantation for CoA. Aortic computed tomography angiography (CTA) revealed a penetrating ulcer in the anterior wall of the ascending aorta with an intramural hematoma, and intraoperative findings confirmed a Stanford type A aortic dissection. The patient underwent one-stage bypass grafting from the ascending to the descending aorta, aortic sinusoplasty, and ascending aorta replacement under cardiopulmonary bypass. The postoperative course was uneventful, and she was discharged in stable condition. Conclusions: One-stage bypass grafting combined with ascending aorta replacement and sinusoplasty provides a safe and effective treatment strategy for complex aortic dissections following CoA stenting. This surgical approach may be considered for a broader population of patients with similar presentations.
