We propose a novel surgical method termed “Jumping Bypass” to prevent hyperperfusion and to reduce the risk of uneven distribution of cerebral blood flow when performing an emergency superficial temporal artery (STA)-middle cerebral artery bypass to treat progressive atherosclerotic cerebral infarction. This method aims to improve blood circulation in two distant areas and to reduce the risk of hyperperfusion using a single STA as a bypass route for establishing side-to-side and sideto-end anastomoses. The presented case is of an atherosclerotic stroke in a 79-year-old woman. After a single STA was secured, the proximal part was anastomosed side-to-side to an artery on the temporal lobe, and the STA at the distal part was anastomosed to a branch on the frontal lobe. This method resulted in the rapid recovery of symptoms without resulting in hyperperfusion syndrome. This may be a useful surgical method in situations where hyperperfusion is unavoidable or when a single bypass may result in an uneven blood flow distribution.
