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

Abstract

In the United States, current endovascular repair of proximal 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 endoleak and subsequent dissection-related aneurysmal degeneration in the aortic arch.
