Abstract

Objective To describe our experience with very distal placement of the Neuron 6 F 0.053 inch inner luminal diameter guide catheter (Penumbra Inc, San Leandro, California, USA) within the intracranial and extracranial vasculature to allow treatment of various neurovascular pathologies. Previously, this was thought to be only possible with a microcatheter.

Methods 12 cases are presented in which traditional guide catheters were unable to successfully navigate tortuous anatomy or provide stable support for intervention.

Results The Neuron 6 F 0.053 inch inner luminal diameter delivery catheter (Penumbra) was placed in a very distal location within the internal carotid artery, external carotid artery and venous system enabling successful endovascular treatment of the intracranial pathology with no related neurological complications.

Conclusion All lesions were successfully treated through a microcatheter advanced in a coaxial fashion through the distally placed guide catheter. There were no complications related to the distal position of the guide catheter.
