Intracranial Large Aneurysms: Endovascular Treatment and Following-up (a Report of 109 Cases)

Objective To explore the technique of endovascular treatment of intracranial large aneurysms and its curative effect on them. Methods The clinical data of 109 patients with intracranial large aneurysms who underwent endovascular treatment from January, 2000 to December, 2006 were analyzed retrospectively. All the patients, except 2 patients, were followed up from 8 to 36 months. Results Of 109 patients, 99 (90.8%) received good recovery, 8 (7.3%) poor recovery, and 2 (1.8%) died. In 101 patients with 105 large aneurysms treated by endovascular embolization, the lumina of 73 aneurysms were embolized by 100%, 21 by 90%～95%, and 11 by 80%. The aneurysms in 8 patients were treated by occlusion of the parent arteries. Rebleeding did not occur during the following -up in 107 patients receiving following -up. DSA or MRA examination in 58 patients showed that 9 aneurysms were recanalized during following -up. Conclusion Endovascular embolization is a safe and effective method to treat intracranial large aneurysms.
