N2 - Purpose: Patients with complicated ascending aortic pathology, including patients with acute type A aortic dissection may be at extreme risk for open repair. Thoracic endovascular aortic repair (TEVAR), infrequently used for the ascending aorta, may be considered an alternative in this setting. We describe early results for emergency and compassionate (E&C) use of a novel endograft, specifically designed for use to treat pathology of the ascending aorta. Materials and Methods: This case series evaluated 19 patients (mean age, 68.84±13.12 years; 57.9% female) treated with ascending TEVAR for acute and chronic acute (4), subacute (1), or chronic (1) aortic dissection or pseudoaneurysm (13). Six of the 19 patients (31.5%) were treated under compassionate use and 13 patients (68.4%) were treated under the emergency use exemption. Ten patients (52.6%) received additional devices to extend treatment into the arch and descending aorta. Results: Device delivery was achieved in all patients (100%). Thirty-day mortality and stroke occurred in 3 patients (15.8%) and in 1 patient (5.3%), respectively. In 1 patient (5.3%), with an Unanticipated Adverse Device Event, the aorta ruptured when the endograft eroded into the adventitial portion of dissection site at the posterior aspect of the ascending wall. Devices were explanted in 2 patients (10.5%), 353 and 610 days after the index procedure, respectively. Six patients had endoleaks (31.6%), including type I (n=2, 10.5%), type II endoleaks (n=3, 15.8%), and indeterminate endoleak (n=1, 5.3%). Conclusions: Delivery and deployment of a novel ascending thoracic stent graft with or without an additional branched arch extension is feasible in patients with complex anatomy and pathology, including acute aortic dissection and pseudoaneurysm. Additional experience with this novel device will further refine the patient population most suitable for endovascular ascending aortic repair for these pathologies. Clinical Impact: This study describes a novel stent graft specifically designed for treatment of ascending aortic pathology, including acute type A dissection. The patients described in this series constituted a group outside the formal US FDA sponsored clinical trial, and were those accepted as part of an emergency and compassionate use basis.
