Endovascular Graft Anchoring Different Regions of Ascending Aorta in the Treatment of Ascending Aortic Dissection

Aortic dissection is a deadly and dangerous disease. About 28% of patients with ascending aortic dissection can't tolerate open surgical trauma caused by thoracotomy and cardiopulmonary bypass, and the prognosis is poor. Minimally invasive endovascular treatment has been applied in the treatment of descending aortic dissection. However, due to the special anatomical structure and high speed /pressure blood flow, the treatment of ascending aorta dissection has become an international difficulty.
