What Is a Bentall Procedure?

Bentall surgery is also known as "ascending aortic valve replacement with aortic valve prosthesis." It is a surgical method to treat ascending aortic aneurysms. Applicable to patients with ascending aortic dissection aneurysms involving coronary sinus or aortic insufficiency. Surgery is usually performed with a deep hypothermic circulation pause. The main surgical procedure is to insert the donor blood vessel in the right femoral artery, insert the leading blood vessel in the right atrium, and then switch to the artificial heart-lung machine for flow. When the body temperature drops to 26 ° C, clamp the distal ascending aorta of the lesion and infuse cardiac arrest fluid. Free ascending aorta, remove the ascending aortic diseased section, retain its posterior and left and right coronary artery openings, remove the aortic valve, transplant the valved artificial blood vessel, and then transplant the left and right coronary arteries on the artificial blood vessel. Anastomosis with the distal end of the ascending aorta. Surgical complications were pseudoaneurysm formation, thrombosis, anastomotic stenosis, and heart failure. The elective surgical mortality rate is 5%, and emergency surgery is 16%. ^[1]

Bentall surgery, that is, the replacement of the ascending aortic root and aortic valve with a valved vascular prosthesis, and the transplantation of left and right coronary arteries, is the preferred surgical method for surgical treatment of Marfan syndrome.
