Approximately 1 month after the drainage, a vertebral aneurysm was detected ventral to the spinal column at the C3/4 intervertebral level (Fig. 1).
Digital subtraction angiography of the right vertebral artery shows an aneurysm located between transverse foramina of third and fourth cervical vertebrae. A, B: First examination; anteroposterior view and lateral, retrospectively. C, D: Second examination 7 days after the first. Anteroposterior view and lateral, retrospectively. The aneurysm grew from 20 mm to 28 mm in height.

The aneurysm continued growing enough to compress the trachea, though sepsis attained remission due to intensive antibiotic therapy (Fig. 2).
At the end of the treatment, the digital subtraction angiogram shows total exclusion of the aneurysm with preservation of a normal vertebral lumen. A: Anteroposterior view, B: lateral view. Arrows indicate both ends of the stent-graft.

Postoperative angiography showed that Jostent GraftMaster was deployed successfully with aneurysm exclusion and patency of the parent artery (Fig. 3).
Computed tomography (CT) angiography with multi planer reconstruction 4 years after the procedure shows the stent-graft fully patent without deformation. Complete exclusion of the aneurysm was observed during the follow-up period. A: Anteroposterior view, B: oblique view.

Infectious symptoms have not been observed since the stent was placed (Fig. 4).
