A novel technique to visualize true lumen in endovascular treatment of the occlusive carotid dissection and the usefulness of external-internal carotid collateral channel

摘要

Background: Dissection of the internal carotid artery (ICA) can cause occlusion or severe stenosis and is known to be one of the major causes of ischemic stroke in the young. Endovascular treatment is one of the useful options for carotid dissections, but passing the guidewire through the occlusion (lesion-cross) and confirmation of the true lumen are sometimes difficult.
