[A case of giant aneurysm of the posterior cerebral artery, treated with a detachable balloon]

Abstract

We report a case with a giant PCA aneurysm successfully treated using the detachable balloon technique. The case was a 52 year-old man with episodes of minor stroke probably due to the giant aneurysm. The aneurysm was located in the P2 segment of the right PCA and was broad-based. Clipping of the neck was considered to be impossible and proximal clipping was the alternative treatment. Instead of surgery, proximal occlusion of the PCA was performed with the use of a detachable balloon.
