Regional cerebral oxygen saturation guided cerebral protection in a parturient with Takayasu's arteritis undergoing cesarean section: a case report ★★★

•Takayasu’s arteritis (TA) is a rare disease that usually affects pregnant women.•TA commonly compromises the perfusion of vital organs, such as the brain.•TA can complicate the anesthetic management of cesarean section.•rScO2 may act as an early warning sign of cerebral ischemia in parturients with TA.•rScO2 guided therapy may prevent cerebral complications in parturients with TA.

The objective of this case report is to present the successful use of regional cerebral oxygen saturation (rScO2) monitoring guided cerebral protection for cesarean delivery in a parturient with Takayasu's arteritis at 38 weeks' gestation. The parturient presented with impaired cerebral and renal perfusion. Titrated epidural anesthesia was performed. During the procedure, we used rScO2 guided cerebral protection strategies, which helped to optimize cerebral oxygen delivery and prevent cerebral complications.
