This case report describes a rare case of bare metal stent migration and subsequent distal stent graft-induced new entry (SINE) after the PETTICOAT technique for aortic dissection. The postoperative course was successful and the patient remains in good health.
Purpose: To report a unique case of bare metal stent migration in the overlapping zone and subsequent distal stent graft-induced new entry (SINE) after the Provisional Extension to Induce a Complete Attachment (PETTICOAT) technique for aortic dissection. Case report: A 67-year-old man underwent thoracic endovascular aortic repair (TEVAR) using the PETTICOAT technique for acute complicated type B aortic dissection. The postoperative course was uneventful, and follow-up computed tomography (CT) showed not only favorable aortic remodeling but also progressive bare metal stent migration in the overlapping zone between the stent graft and the bare metal stent. A 6-month postoperative CT revealed a distal SINE, and the patient underwent re-TEVAR to cover the new entry. Postoperative CT demonstrated successful repair of the distal SINE. The patient is currently in good health 2 years after the reintervention. Conclusion: Surgeons should consider the potential risk of device migration due to favorable aortic remodeling after TEVAR for aortic dissection, especially with the use of additional bare metal stents.
