Abstract:
Aortic dissection (AD) is a condition in which high-velocity, high-pressure blood flow in the aortic lumen enters the mesentery through a tear in the aortic intima, forming a coarctation hematoma that expands and dissociates in the aortic mesentery, resulting in pathological changes in both the true and pseudolumen. Aortic dissection has a high morbidity and mortality rate, especially in acute type A aortic dissection. Once diagnosed, type A aortic dissection should be actively treated surgically. Surgery is still the gold standard of treatment for type A aortic dissection. Despite surgical advances, the postoperative mortality rate for type A aortic dissection remains high. When conventional treatment fails and patients develop postoperative cardiopulmonary dysfunction and circulatory collapse, in severe cases leading to death. The use of mechanical circulatory assist devices for the treatment of postoperative cardiogenic shock after aortic dissection has been reported on a constant schedule, and the latest developments are described in this review.
