Iatrogenic perforation of a branch of the descending thoracic aorta during catheter ablation of the left lateral accessory pathway: a case report

Introduction and importance: The iatrogenic acute aortic syndrome is one of the fatal complications of the endovascular procedure. Identifying and managing such complications is crucial for optimal patient outcomes. Case presentation: We report a case of left lateral accessory pathway with successful ablation and perforation of a branch of the descending thoracic aorta during the procedure, which was treated by implanting an endovascular stent graft in the thoracic aorta. Clinical discussion: Appropriate imaging and early intervention with endovascular repair can be key to the successful management of patients with aortic perforation. Conclusions: Aortic computed tomography angiography is the gold standard method for diagnosis, and the endovascular approach could be a therapeutic option in these cases.
