ENDOVASCULAR TREATMENT OF MULTIPLE ANEURYSMS INVOLVING THE POSTERIOR INTRACRANIAL CIRCULATION

The results of surgery on multiple intracranial aneurysms that involve the vertebrobasilar circulation are poor, and associated patient mort ality remains high. We describe the endovascular treatment of four pat ients with multiple aneurysms that involved the posterior intracranial circulation. Satisfactory occlusion of all aneurysms was achieved by using electrolytically detachable coils, and all patients had a good c linical recovery. Our early experience suggests that endovascular coil occlusion may be a particularly suitable method for treating this hig h-risk condition.
