Endovascular revascularization of a stenotic lesion requires appropriate stent positioning. In particular, stenting of the common carotid artery (CCA) ostium makes it difficult to avoid proptosis into the aorta. Furthermore, the guiding catheter may become unstable during the stenting because of its position under the aortic arch. To resolve these problems, we performed antegrade stenting for a patient with a symptomatic stenotic left CCA ostium that was treated by lifting a balloon-guiding catheter with a gooseneck snare. Our patient was a 74-year-old man who presented to the hospital with main complaints of right hemiparesis and motor aphasia. A left cerebral infarction due to severe stenotic left CCA ostium was diagnosed. A CT perfusion study showed decreased cerebral blood flow in the left hemisphere. Stenting of the stenotic left CCA ostium was performed using an antegrade approach. A balloon-guiding catheter positioned under the aortic arch was inflated and lifted from the right brachiocephalic artery using a gooseneck snare. The guiding catheter was stabilized during stenting. This method is highly effective for stenting CCA ostium.
