Stenting Combined with Coil Embolization of a Dissecting Aneurysm after Traumatic Vertebral Artery Injury

抄録

Objective: We report a case of dissecting aneurysm developed after traumatic vertebral artery dissection (VAD) treated by stenting combined with coil embolization.

Case Presentation: A 47-year-old man was injured in a fall and presented with left VAD associated with central spinal injury due to C2 fracture. One week after admission, magnetic resonance imaging (MRI) demonstrated contralateral VAD with a dissecting aneurysm. Due to bilateral VAD, we employed coil embolization and stenting for the dissecting aneurysm to prevent rupture and embolic events, and to maintain the patency of the dominant right VA. There were no complications during the perioperative period. The follow-up angiogram 6 months after embolization confirmed obliteration of the dissecting aneurysm and patency of the parent artery.

Conclusion: Stenting combined with coil embolization is an effective treatment for traumatic VAD with a dissecting aneurysm.
