Direct surgery for the aneurysms at the C3 portion of the internal carotid artery (ICA) requires relatively complicated procedures. We present three patients with this aneurysm who underwent endovascular embolization. The remodelling technique was utilized in two of these patients with unruptured aneurysms. Sufficient obliteration was achieved in every case. Endovascular embolization may be an important alternative for ICA C3 aneurysms.
