Endovascular treatment of intracranial vertebrobasilar artery dissecting aneurysms: Parent artery occlusion versus flow diverter

PAO and FD treatment are both feasible options for treatment of VBDAs. PAO provide higher immediate complete occlusion rate compared to FD. Despite low initial complete occlusion rates, FD group presented a comparable long-term outcome and similar perioperative events rate compared to the PAO group.
