Type A aortic dissection (TAAD) is a potentially life-threatening pathology associated with significant risk of mortality and morbidity. In acute forms of type A aortic dissection (TAAD) mortality is 50% by 24 h and 50% of patients die before reaching a specialist center. Rapid diagnosis and subsequent prompt surgical repair remain the primary goal for these patients. In the last decade it has been observed that improvements in diagnostic techniques, initial management and increased clinical awareness have contributed to a substantial increase in the number of patients benefiting from a prompt diagnosis and undergoing surgery.However, survival after surgical repair has not yet reached optimal follow-ups and is burdened by high in-hospital mortality(16-18%)The main approach to acute type B non-complicated aortic dissection (TBAD) has always been to use medicines to control the patient's heart rate and blood pressure. However, recent findings suggest that a large number of patients treated for acute complicated (TBAAD) and non-complicated TBAD experience aortic complications, such as aneurysmal degeneration, at a later stage.

The purpose of this study is to assess the role endovascular therapy to treat aortic disease involving the ascending aorta, the aortic arch, and the visceral segment of the aorta (or thoracoabdominal aorta)
NCT07405242
This study is a single-arm, open-label, multi-center clinical trial evaluating the safety and efficacy of endovascular treatment for retrograde dissection involving the ascending aorta that is not suitable for open surgery. The aim is to assess the short-term (30 days) and medium- to long-term (6 months and 12 months) safety and efficacy of endovascular treatment in patients with retrograde dissection involving the ascending aorta who are not suitable for open surgery. The study plans to include patients with dissection confirmed by imaging, with the tear located in the aortic arch or descending aorta and extending retrogradely to the ascending aorta, and the most distal segment of the dissection is at least 2 cm away from the coronary artery ostia. These patients have been evaluated by cardiac surgery and found to be unsuitable for open surgery, with significant risks or risks outweighing benefits associated with open surgery. This is a single-arm, open-label, multi-center study, and no blinding or randomization will be used, nor will stratification factors be set. After successful screening, the subjects will undergo endovascular treatment for aortic dissection (stent implantation) during the operation. The subjects will be followed up for one year after the operation, and the safety and efficacy of endovascular treatment for retrograde dissection involving the ascending aorta will be evaluated based on the subjects' survival status, the occurrence of surgery and disease-related complications, and the recovery of the disease.
NCT04544579
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.
NCT03917862
SASH Trial is a multicenter, prospective, open and randomized 1:1 study. The aim of this study is to evaluate the efficacy of TDM-621(Three-D Matrix- 621) (PuraStat®) on hemostasis of ascending aortic surgery. The TDM-621 is a topic hemostatic product. When in contact with blood it allowed to cover the sutures improving the hemostasis. The hypothesis is that the use of TDM-621 may reduce bleeding and the need for blood transfusion of patients undergoing ascending aortic surgeries. It will include 200 consecutive patients randomized to receive TDM-621 or regular procedure, performed in 5 different centers.
