Objective:
The authors report the prompt diagnosis and endovascular treatment with the "Sandwich" technique of a chronic contained rupture of a thoracoabdominal aortic aneurysm in an unfit patient for open surgery.
Methods:
A 57-year-old male patient with severe pulmonar and cardiac comorbilities presented at the emergency department with a contained rupture of a type V thoracoabdominal aneurysm, involving the celiac axis. A "Sandwich" technique was performed deploying a ViaBahn graft through a transbrachial access interlayed by two Gore TAG endoprothesis.
Results:
At the term of the 1st month of follow-up, no endoleaks were observed.
Discussion:
An impending ruptured thoracoabdominal aortic aneurysm was successfully excluded using the "Sandwich" technique, in a patient unfit for the conventional open correction.
