Abstract: BACKGROUND: The treatment of ruptured dissecting aneurysms of the intracranial vertebral artery (VA) with parent vessel preservation is a challenge for neurosurgeons and interventional neuroradiologists. OBJECTIVE: To propose an indication for flow-diverting treatment for reconstruction of a dissecting VA with acute subarachnoid hemorrhage. METHODS: Two male patients transferred after acute subarachnoid hemorrhage and dissecting aneurysm on the V4 segment of the dominant VA. An occlusion test was not performed because of their poor clinical state. A flow-diverting stent represented by the Pipeline embolization device was suggested to both patients. RESULTS: Three Pipeline embolization devices were deployed in each VA. One dissecting aneurysm was excluded immediately after 3 stents, and 1 patient had complete exclusion demonstrated at the 48-hour control. No morbidity directly related to the procedure was observed. No recanalization and no rebleeding occurred during the 3 months of follow-up. CONCLUSION: A flow-diverting stent may be considered an option to treat ruptured dissecting aneurysms of the VA, providing remodeling of the parent vessel and complete exclusion of the aneurysm.
