We review recent developments in the pathophysiology and management of intracranial aneurysms and subarachnoid hemorrhage (SAH), and discuss some of the controversies. Topics were chosen on the basis that they would contribute to a better understanding and/or provide new therapeutic options for the management of SAH and its sequelae. Vasospasm, myocardial dysfunction, the timing of surgery, endovascular therapy, induced hypotension, cerebral protection during aneurysm surgery, and choice of anesthetic agents are all discussed.
