We report a postpartum dissecting aneurysm of the right vertebrobasilar artery in a 31-year-old woman that was confirmed by angiographic identification of a double lumen.The intracranial segment of the right vertebral artery was thrombosed proximal to the aneurysm.The patient, managed conservatively,recovered well and,when reexamined 2 months later, was found to be neurologically intact.A repeat angiographic study at that time demonstrated that the aneurysm had resolved.Conclusions:Proximal occlusion may have protected the aneurysm from rupture and further dissection,thereby making surgery unnecessary. |
