Aortic dissection occurs when a tear develops in the inner wall of the aorta, allowing blood to flow between the layers of the artery wall and creating a false channel. This can weaken the vessel, reduce blood supply to vital organs, and increase the risk of aortic rupture. Aortic dissection repair surgery is performed to remove or stabilize the damaged section of the aorta and restore safe blood circulation. Depending on the severity and location of the dissection, surgeons may use open surgical repair, graft replacement, or advanced endovascular techniques. The procedure is commonly performed in specialized cardiac centers equipped for emergency cardiovascular care and requires careful postoperative monitoring to support long term heart and vascular health.
