简要总结
The goal of this clinical trial is to determine whether an upfront invasive strategy of TEVAR plus medical therapy reduces the occurrence of a composite endpoint of all-cause death or major aortic complications compared to an upfront conservative strategy of medical therapy with surveillance for deterioration in patients with uncomplicated type B aortic dissection.
详细描述
The study will be a prospective, pragmatic, randomized clinical trial of the comparative effectiveness of an initial strategy for the treatment of uncomplicated type B aortic dissection (uTBAD). Patients with uTBAD and no prior history of aortic intervention will be randomized within 48 hours to 6 weeks after index admission to one of the two initial strategies. Follow-up will be ascertained via a centralized call center and ascertainment of medical records, as well as remote blood pressure monitoring. Recommendations regarding medical therapy will be made to enrolling centers and feedback on the quality of medical care given, however, all subsequent care, with the exception of aortic interventions, will be at the discretion of the responsible clinical care team. Aortic interventions will allowable only as per protocol.

研究组 & 干预措施
Upfront TEVAR plus Medical Therapy
Participants randomized to upfront TEVAR will receive a commercially available device customized to their individual anatomical requirements. Stent-graft implantation will be performed either in the operating room with appropriate digital imaging equipment to allow fluoroscopic and trans-esophageal echo (TEE) guidance or the catheterization laboratory, angiographic suite (with digital angiographic equipment).

结局指标
主要结局
All-cause death or major aortic complications (MAC)
时间窗: Last follow-up timepoint. Differential follow-up with median of about 4 years
The primary endpoint is a composite of all-cause death or major aortic complications (MAC). MACs are defined as: * Aortic rupture * Malperfusion syndrome * New aortic tear requiring intervention, * Retrograde aortic dissection, * Dependence on outpatient dialysis (chronic) * Major amputation (above ankle) * Tracheostomy * fistula formation (e.g., aorto-esophageal, aorto-tracheal) * Spinal Cord Ischemia with paralysis or paresis * Stroke * AD-related intervention in either group defined as: * Open TAA/TAAA Repair * Fenestrated and/or Branched Endovascular Repair of TAAA * Repeat TEVAR
