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.

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 Dissecting Aneurysm

Background: Intracranial vertebral artery dissecting aneurysm (VADA) is rare and shows high morbidity and mortality rates when the aneurysm ruptures. Endovascular treatment for VADA is one of the optimal treatments, but the dominant side VA and its branches or perforators need to be preserved. We report a novel and successful stent-assisted coil embolization technique using the low-profile visualized intraluminal support (LVIS) stent, with five technical notes in three consecutive cases of unruptured vertebral artery dissecting aneurysm (VADA). Case Description: We report three consecutive cases of unruptured VADA which involved a posterior inferior cerebellar artery (PICA), an anterior spinal artery, and perforators. Stent-assisted coil embolization with the LVIS stent was performed in all patients. The stent was carefully placed to obtain parent artery wall apposition at distal portion and with moderate pushing at aneurysm portion. The LVIS stent was placed with tailor-made wall apposition at perforating arterial side in the barrel view, and coil embolization was performed avoiding doughnut-like stent form to prevent perforator infarcts. All cases showed complete occlusion of the aneurysms with preservation of both parent artery and its branches and perforators patency. In three cases, clinical presentations were improved without ischemic complications. The median follow-up period was 1 year. At present, no recurrence and no complication have been observed. Conclusion: We demonstrate the coil embolization of VADA using LVIS stent with five techniques. Our techniques for the treatment of VADA using LVIS stent are safe and can minimize ischemic complications by creating suitable wall apposition to the orifices of branches or perforators.

Background: Vertebral artery dissecting aneurysm (VADA) involving the origin of the posterior inferior cerebellar artery (PICA) is a complex disease entity in which the dual goals of preventing future rebleeding and maintaining perfusion of the lateral medulla must be considered. We present an illustrative case and review the literature surrounding treatment strategies. Case Description: We report a patient presenting with extensive subarachnoid hemorrhage due to rupture of an intracranial VADA involving the PICA origin. After consideration of the patient’s cerebral vasculature and robustness of collaterals, a flow-diverting stent was placed with angiographic resolution of the lesion and maintenance of antegrade PICA flow. Ultimately, the patient experienced a contralateral intraparenchymal hemorrhage leading to death. Review of the literature identified 124 cases of VADA involving the PICA origin described over the past decade. The methods of surgical and endovascular treatment of these cases were reviewed, with particular focus on the rationale of treatment, outcomes, and complications. Conclusion: Numerous treatment options for VADA involving PICA have been reported with different risk and benefit profiles. Flow-diverting stents appear to offer the most favorable balance of securing the aneurysm and avoiding medullary infarction, but the risks and optimal anti-thrombotic treatment strategy are incompletely understood. In select cases, in which the surgical risk is low or in which the anatomy is favorable (e.g., nondominant parent vessel or robust collateral circulation in the involved territories), parent artery trapping with or without microsurgical revascularization can be considered.

✓ 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.
