In order to limit the Valsalva maneuvers during labor, a caesarean section was performed at term under neuraxial anesthesia without complications with a healthy newborn. CONCLUSION: Chiari malformation type I during pregnancy is rare. Patients diagnosed prior to pregnancy condition a follow-up in which the indication for neurosurgical treatment prior to conception is assessed. During pregnancy, no single method of termination or anaesthesia can be recommended and medical care should be provided by a multidisciplinary team formulating an individualized care plan to improve maternal and fetal outcome. © 2023 Asociacion Mexicana de Ginecologia y Obstetricia.
