Type A acute aortic dissection (TAAAD) is an acute cardiovascular condition that is usually associated with Hypertension or genetic conditions such as Marfan Syndrome, but it can also occur in patients with no known predisposing risk factors. TAAAD is associated with extremely high mortality if not expediated implementation of defeinitive management on time. Surgical management of TAAAD also varies tremendously depending on the presenting complications or causative pathology. Techniques to manage TAAAD cover almost the entire spectrum of methods employed in cardiac surgery ranging from a simple replacement of the ascending aorta to aortic root sparing or replacement, and an aortocoronary bypass to total arch and descending aortic stenting involving hypothermic circulatory arrest and various cerebral protection strategies. New medical evidence suggests that concomitant, intraoperative management of the arch and descending aorta minimizes the need for subsequent surgeries in patients who are operated upon for TAAAD. Coupled with new diagnostic technology available to medical professionals, better long-term patient outcomes for TAAAD treatment are now a reality. |
