Endovascular treatment for internal carotid-ophthalmic aneurysms using detachable coils

Internal carotid ophthalmic (IC oph) anuerysms account for 1.5 8.0% of all intracranial alleurysms. They are difficult to treat by direct surgery, and the surgical results are poor compared with those for other types of aneurysm. We report on the treatment of 4 patients with IC oph aneurysms using interlocking detachable coils (IDC) anti immediately detachable coils (IEDC) via an endovascular approach. The patients were 2 men and 2 women who ranged in age from 44 to 55 years. The aneurysms were small in 3 patients and large in 1. Immediately after embolization, 90 100% obliteration of the aneurysms was achieved in all patients. In the patient with a large aneurysm, more than 90% obliteration was achieved. Follow up angiography 13 days to 6 months after embolization showed no coil compaction. There were no complications during or after the procedure. Clinical follow up findings indicated good recovery in all patients.
