Percutaneous Therapy of Functional Interrupted Aortic Arch with 3-1 Dimensional Printing Guidance

Functional interrupted aortic arch is a congenital malformation characterized by a complete separation between the ascending aorta and the descending aorta. Untreated patients are in danger of having late complications including cerebral hemorrhage, aneurysm formation, and aortic regurgitation. Traditionally, classical surgical therapies included bypass grafting or orthotopic repair. Herein, we report a simplified percutaneous therapy for functional interrupted aortic arch with a retrograde crossing technique and without an incremental-sized expandable balloon. With the guidance of 3-dimensional printing, percutaneous treatment with a covered stent is a feasible, safe, and effective alternative to surgery with excellent short- and midterm results in selected patients with favorable anatomy.
