Angiographic study of the growth of intracranial aneurysms

Abstract

✓ The authors have attempted to assess whether there is any standard rate of growth of intracranial aneurysms. Angiographic studies were performed on 67 patients with 82 aneurysms with intervals between angiograms ranging from a few days to 10 years. Examination of these records showed no consistent rate of change in size, possibly partly because of inherent inaccuracies in the method, which are discussed. The clinical reasons for the repeat studies are briefly mentioned. It is concluded that it is unwise to wait and see what may happen to any but perhaps the smallest aneurysm.
