Cerebral angiography in posterior fossa revascularization

With advances in microsurgical techniques and refinement of cerebral angiography, many new surgical approaches for the treatment of vertebrobasilar insufficiency (VBI) have been developed. Detailed selective cerebral angiography for confirming the clinical diagnosis, for demonstrating the exact anatomical and topographical vascular pathology, and for deciding on the best surgical procedure. Angiography is recommended to evaluate treated patients both in the early and late postoperative periods. It is an essential element of any future randomized study to assess the value of surgical vs medical treatment of patients with VBI. The benefits of cerebral angiography far outweigh the small risk associated with the procedure.
