Treatment of multiple intracranial aneurysms by neurosurgery and endovascular embolization

Objective To investigate the diagnosis, surgical opportunity and therapeutic method of the multiple intracranial aneurysms. Methods DSA or 3D-CTA were performed before the operation in 48 patients with 105 intracranial aneurysms. Of 48 patients with intracranial aneurysms, 41 were treated by craniotomy and/or endovascular embolization, and 7 gave up treatment. Of 41 patients with multiple intracranial aneurysms receiving the treatment, 29 underwent only one unilateral craniotomy, 1 did only one bilateral craniotomy, 4 did two craniotomies, 4 did endovascular embolization and 3 did craniotomy and endovascular embolization. Results Ninety-one aneurysms were successfully clipped or embolized in 41 patients. Of 41 patients followed up from 3 to 5 years, 39 did not suffered from intracranial rebleeding and 2 did due to the rupture of the aneurysms 2 and 4 years respectively after the operation. Conclusions 3D-CTA is helpful to the diagnosis and postoperative reexamination of the multiple intracranial aneurysms. The cerebral angiography is still the gold standard of the diagnosis of the multiple intracranial aneurysms. The multiple intracranial aneurysms should treated as early as possible in order to improve the prognosis of the patients.
