A major advantage of performing an<unk>  over placement of a cerebrospinal fluid shunt is the absence of an implanted foreign body. A shunt has risk of infection and failure for which subsequent surgery is needed. Complications of<unk>  include hemorrhage (the most severe being due to basilar artery rupture), injury to neural structures (e.g. hypothalamus, pituitary gland or fornix of the brain), and late sudden deterioration. Infection, hematoma, and cerebrospinal fluid leaks may present in the direct postoperative period.
