The clinical material to be discussed is derived from a series of 1767 patients with vertebral-basilar aneurysms operated upon at the teaching hospitals of the University of Western Ontario in London, Canada; at Victoria Hospital 1959–1972 (140 patients), at University Hospital 1973–1992 (1540 patients) and at the University of Miami in Miami, Florida at Jackson Memorial Hospital 1991–1992 (31 patients). Fifty-six (56) other patients were operated upon at other university clinics as a visiting surgeon. Ninety-five (95) percent of the patients were operated on by the two senior authors.
