Double Origin

Background Double origin of the posterior inferior cerebellar artery (DOPICA) has been rarely reported in the literature, with a reported incidence of 1.45%. In contrast, a high concurrence rate of DOPICA and vertebral artery dissecting aneurysm has been reported. Clinical presentation A 61-year old woman presented with vomiting and diplopia with preceding headache. Magnetic resonance imaging (MRI) showed fresh infarction of the left lateral medulla and a vertebral artery dissecting aneurysm of the left vertebral artery. The next day, she exhibited transient loss of consciousness and worsening of headache, and MRI depicted subarachnoid hemorrhage. Four-vessel digital subtraction angiography showed a posterior inferior cerebellar artery (PICA) arising both intracranially and extracranially from the left vertebral artery. Although the dissecting lesion involved the V3 and V4 portion, it did not involve an extracranially originating PICA. Internal trapping of the V3 and V4 portion was chosen as the extracranial channel was expected to supply the PICA territory. This procedure was safely performed. Conclusion Early endovascular intervention should be considered in the treatment of dissecting aneurysm of vertebral artery associated with DOPICA for patients with relatively long lesions even in unruptured cases.

Vertebral Artery Stenting

We herein report a case of a ruptured vertebral artery dissecting aneurysm involving the origin of the posterior inferior cerebellar artery that was treated using the stent-jack technique. After parent artery occlusion of the distal vertebral artery, stenting of the posterior inferior cerebellar artery was performed. Further coiling was needed because distal vertebral artery recanalization occurred due to transformation of the coil mass. The stent-jack technique for a ruptured vertebral artery dissecting aneurysm involving the origin of the posterior inferior cerebellar artery is effective; however, careful attention to recanalization after stenting is needed due to transformation of the coil mass.

✓ The author presents the case of a patient with a ruptured vertebral artery dissecting aneurysm in which the posterior inferior cerebellar artery (PICA) arose from the wall of the aneurysm. The aneurysm was treated by trapping and the PICA was anastomosed to the vertebral artery proximal to the dissection. This technique allows intraoperative obliteration of the aneurysm while maintaining normal blood flow to the PICA.
