Hybrid Operation for a Brachiocephalic Aneurysm in a Young Woman With Loeys–Dietz Syndrome

Abstract

In the currently evolving field of endovascular surgery, most brachiocephalic aneurysms are treated with stent grafts. Connective tissue disorders are considered a relative contraindication for endovascular repair because of the risk of adverse events at the landing zone in the aorta and its branches, although the surgical grafts from previous repairs could provide stable landing zones. We attempted a new hybrid operative technique for a brachiocephalic aneurysm in a patient with Loeys-Dietz syndrome, who was unsuitable for open surgery because of multiple previous surgeries and possible lung malignancy. The operation was performed by creating an appropriate landing zone using a prosthetic graft followed by endovascular stent grafting, which yielded good results. This hybrid operation is expected to expand the potential for endovascular treatment in patients with connective tissue diseases who are deemed unsuitable for open surgery.
