Overview and Facts about Aortic Dissection Surgery
Aortic dissection surgery can be a critical, life-saving procedure in cases of dissection of the aorta. Dissection occurs when a tear forms in the inner lining of the aorta, the major blood-supplying artery of the body. The tear separates the inner layers of the aorta, resulting in an accumulation of blood in one of the passages created.
This may lead to decreased blood supply to the organs or the rupture of the aorta. Aortic dissection is particularly dangerous if it occurs in the ascending aorta, the section of the artery closest to the heart.
Surgical repair is necessary in cases of dissection of the ascending aorta. The procedure involves the removal and replacement of the damaged tissue with a synthetic graft.
What to Expect during Aortic Dissection Surgery
Aortic dissection surgery is performed in the hospital by a cardiac surgeon trained and experienced in the procedure. You will remain asleep under general anesthesia for the entirety of the surgery.
Because it is necessary to stop the heart while the dissection is being repaired, oxygenated blood will be circulated throughout your body by way of a heart-lung machine.
The surgeon will open your chest with an incision atop the breastbone and clamp the aorta on either side of the affected area. The dissected section of the aorta will be removed, and the synthetic graft will be sutured in place.
The surgery may take between four to eight hours, depending on the area/extent of the dissection and the presence of any coexisting conditions.
You should expect to remain hospitalized for about a week, with a day or more spent in the intensive care unit immediately following the procedure. Your heartbeat, blood pressure and blood flow will be monitored as you recuperate, and tubing may remain placed in your chest to drain any post-surgery fluid.
Before discharge, your cardiac care team will provide you with detailed instructions on continuing your recovery at home, including incision care, activity restrictions and cardiac rehabilitation guidance.
