[[Cerebral revascularization]] dates back to [[1953]] when Conley performed the first reported [[saphenous vein graft]] (SVG) bypass of the [[cervical internal carotid artery]] (ICA) for a tumor of the neck ((CONLEY JJ. Free [[autogenous]] [[vein graft]] to the internal and common [[carotid]] arteries in the treatment of [[tumor]]s of the [[neck]]. Ann Surg. 1953 Feb;137(2):205-14. doi: 10.1097/00000658-195302000-00009. PMID: 13017520; PMCID: PMC1802458.)). In [[1971]], Lougheed and colleagues performed the first long-segment [[saphenous vein graft]] (SVG) bypass from the common carotid to the [[intracranial]] [[ICA]] ((Lougheed WM, Marshall BM, Hunter M, Michel ER, Sandwith-Smyth H. Common carotid to intracranial internal carotid [[bypass]] [[venous graft]]. [[Technical note]]. J Neurosurg. 1971 Jan;34(1):114-8. doi: 10.3171/jns.1971.34.1.0114. PMID: 5539642.)). Fisch and associates ((Fisch UP, Oldring DJ, Senning A. Surgical therapy of internal carotid artery lesions of the skull base and temporal bone. Otolaryngol Head Neck Surg (1979). 1980 Sep-Oct;88(5):548-54. doi: 10.1177/019459988008800507.

Saphenous vein graft bypass of the cavernous internal carotid artery. J Neurosurg. 1990 Jan;72(1):35-41. doi: 10.3171/jns.1990.72.1.0035.

Although first described in the setting of cervical neoplasms, [[cerebral revascularization]] was primarily developed for the prevention of [[stroke]] in [[chronic cerebral ischemia]] due to [[carotid artery stenosis]]. This practice flourished through the [[Superficial temporal artery to middle cerebral artery bypass]] (STA-MCA) [[bypass]] until it peaked in [[1985]], when the EC/IC Bypass Study Group ((EC/IC Bypass Study Group. Failure of extracranial-intracranial arterial bypass to reduce the risk of [[ischemic stroke]]. Results of an international randomized trial.
