Complications after obliteration of the superior petrosal vein: Are they rare or just underreported?

Dandy first described the course of the superior petrosal vein (SPV) and its importance during surgery in 1929. Although it has been reported that this vein can be sacrificed without complication, unfavourable outcomes may occur after dividing the SPV. We review these consequences, which may include peduncular hallucinosis and hearing loss, or even hemorrhage, and discuss factors that may contribute to complications. Preservation of the SPV should be attempted whenever possible to increase the safety of surgery. (C) 2016 Elsevier Ltd. All rights reserved.
