Successful Hybrid Management of a Left Vertebral Artery Aneurysm Secondary to Type-1 Neurofibromatosis

A 32-year-old man with type-1 neurofibromatosis (NF1) was diagnosed with a left vertebral artery aneurysm of 4 cm maximal diameter. A hybrid procedure was conducted associating the exclusion of the origin of the left vertebral artery with a covered stent in the left subclavian artery and a cervical incision for ligation of the vertebral artery to completely exclude the aneurysm and perform the aneurysm resection. The histologic findings confirmed the diagnosis of NF1 with a vascular localization in the aneurysm. The postoperative course was uneventful. The 1-year clinical and morphologic results were satisfactory.
