OBJECTIVE:
To compare complications of neurosurgical clipping with complications of endovascular coil therapy in the treatment of ruptured aneurysms.

METHODS:
Study compared complications, hospital stay durations, and costs of neurosurgical clipping with those of endovascular coil therapy in treatment of unruptured aneurysms at 60 university hospitals from June 1994 through June 1997. The primary treatment was surgery in 2,357 cases and endovascular in 255 cases.

CONCLUSION:
Endovascular coil treatment resulted in fewer adverse outcomes than surgery for unruptured cerebral aneurysms.
