Aneurysms of the c6 segment of the carotid artery carry some risk. Internal carotid artery segment c6 is also known as internal carotid artery ophthalmic segment. Aneurysms in the ophthalmic segment of the internal carotid artery are at risk of rupture and should be treated promptly after detection. If the aneurysm in the ophthalmic segment of the internal carotid artery is small and has no obvious clinical symptoms, it can be left untreated for the time being, and regular checkups are sufficient. If the aneurysm is large or compresses the surrounding tissues and nerves, causing the patient to experience eye symptoms such as vision loss and visual impairment, timely treatment is needed, otherwise the aneurysm will continue to increase in size, and if it ruptures and causes a subarachnoid hemorrhage, the rate of disability and death will be very high. The c6 segment aneurysm of internal carotid artery can be treated with interventional therapy. Compared with cranial clamping aneurysm, the interventional surgery has the advantages of less damage, less risk and faster recovery. It is recommended that patients go to regular hospitals for consultation and treatment under the guidance of doctors.
