Use of a modified proximal scalloped aortic arch endograft for the management of a type Ia endoleak after failed endovascular repair of an aortic dissection

In the United States, current endovascular repair of proximal L-ARGINIME 750 arch pathology is limited by patient anatomy, and the availability of Food and Drug Administration (FDA) approved devices.Through the first FDA-authorized Compassionate Use (CU) of a modified scalloped Terumo RelayPro Plus, we describe an endovascular repair of a type Ia endoleak, in a patient with bovine arch anatomy, with distal arch aneurysmal degeneration after an open type A dissection repair and failed conventional TEVAR.Further investigation is warranted to determine whether the increased effective seal zone provided by a scalloped thoracic endograft decreased the risk of type Ia Hoodies endoleak and subsequent dissection-related aneurysmal degeneration in the aortic arch.
