Cerebrospinal fluid as vaginal discharge: ventriculoperitoneal shunt migration following Cesarean section

Congenital hydrocephalus was once a permanently disabling and even fatal disease. With the advent of ventriculoperitoneal shunts, affected women are now surviving to their reproductive years and beyond. Pregnancy outcomes in this population are generally positive. However due to possible shunt complications, including infection, migration, and organ perforation, perinatal care for pregnant individuals with a ventriculoperitoneal shunt is complex and requires input from both obstetric and neurosurgical providers. We present the case of a 28-year-old G1P1 with a history of congenital hydrocephalus and ventriculoperitoneal shunt who presented to the emergency department at two months postpartum with clear fluid leaking from her vagina. The shunt's distal end had migrated and perforated the uterus causing cerebrospinal fluid to leak into the uterine cavity. Surgical repair was required of both the uterine hysterotomy and ventriculoperitoneal shunt, and the patient's symptoms ultimately resolved. Patients with a history of shunt placement who later undergo abdominal surgery, including cesarean section, are at risk for shunt complications. Shunt-dependent patients presenting in the post-partum period with new neurological or abdominopelvic complaints should undergo evaluation by a multidisciplinary team.
