Background:
Unruptured extracranial vertebral artery (VA) aneurysms are uncommon and have rarely been described with treatment options. Here we report the successful reconstruction of an asymptomatic extracranial left VA aneurysm, highlighting the treatment for extracranial VA aneurysm and showing the superiority of a hybrid operating room in cerebral vascular diseases.
Case Description:
In this 57-year-old female who had sustained an extracranial left VA aneurysm, magnetic resonance angiography showed bilateral VAs as codominant in the vertebrobasilar system. Digital subtraction angiography demonstrated that the fusiform aneurysm (18.7 × 15.4 mm) was present at the proximal part of the left VA. Aneurysm resection and vascular graft reconstruction were performed in the hybrid operating room. A successful outcome was noted at the 6-month follow-up.
Conclusions:
Extracranial VA aneurysm in the V1 segment can be well treated with open surgery using a prosthetic graft. Preserving the function of the affected VA should always be a point of concern.

Muscles of the Vertebral Column
Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...
