Endovascular treatment of aortic dissection is a minimally invasive procedure used to treat aortic dissection, a condition where a tear occurs in the inner wall of the aorta. The procedure involves inserting a stent graft through a catheter to seal the tear and restore normal blood flow, preventing further damage to the aorta. Endovascular treatment is preferred over open surgery due to its lower risk, faster recovery, and fewer complications, particularly in high-risk patients.

This procedure is effective in stabilizing the aorta, preventing rupture, and improving long-term survival rates for patients with aortic dissection.
