title: A novel approach using Neuron 6F guiding catheter for the embolization of intracranial aneurysm with coiling of the parent internal carotid artery.
abstract: To describe our initial experience and early outcomes with distal placement of the Neuron 6F guiding catheter through coiled ICA for aneurysmal EVT. We examined the utility of the Neuronf 70 6F guiding catheter for the embolization procedure in such cases, fourteen cases of aneurysm with coiling of the parent ICA are presented via traditional guiding catheters. With the support of 8F ENVOY guiding catheter as a shuttle sheath, the Neuron(TM) 70 6F guiding catheter was successfully placed through coiled extracranial ICA, so the mirocatheter could be delivered to a more strategic position for embolization of the aneurysm. Coiling of extracranial ICA was found as parent artery on angiogram in all patients with ruptured aneurysms. Even where there were two curvatures of more than 360° in the coiled segment of the ICA, Neuron(TM) 70 6F guiding catheter could be placed through the coiling to a distal position and enabled EVT of intracranial aneurysms with no related neurological complications. Neuron guiding catheter is a useful device for embolization of aneurysm where there is coiling of parent ICA, easily placed through the coiling of the ICA and provided robust anatomical support via enhanced catheter-to-vessel wall engagement.
