Thoracoabdominal aortic stent placement is a minimally invasive procedure used to treat aneurysms or dissections in the thoracoabdominal portion of the aorta. During the procedure, a stent is placed through a catheter to reinforce the weakened area of the aorta and prevent rupture, ensuring normal blood flow.

This procedure is crucial for patients with complex aneurysms or dissection involving the aorta, offering a safer, less invasive option compared to open surgery.
