Treatment of a patient with vertebral and subclavian aneurysms in the setting of a TGFBR2 mutation

Abstract

We present the case of a patient diagnosed with hypermobile Ehlers-Danlos syndrome with aneurysms of the subclavian and vertebral arteries. Molecular testing demonstrated transforming growth factor-beta receptor type 2 mutation. She was not a candidate for an open repair; therefore, a hybrid approach involving right vertebral ligation and bypass from the right common carotid to the vertebral C1-2 interface, endovascular exclusion of the left vertebral artery, and stent grafting of the left subclavian/axillary artery was used. The left vertebral embolization proved ineffective, requiring a right-to-left vertebral catheterization with glue occlusion. Based on her proper molecular diagnosis, she underwent prophylactic root and ascending aortic repair.
