Endovascular aortic dissection repair is a minimally invasive procedure used to treat aortic dissection, a condition where there is a tear in the inner layer of the aorta. The procedure involves inserting a stent or graft through a catheter into the affected area to seal the tear and stabilize the aorta, restoring normal blood flow and preventing rupture.

Endovascular repair is often preferred over traditional open surgery due to its lower risk, faster recovery time, and fewer complications, particularly in high-risk patients.
