Uterine perforation by a cystoperitoneal shunt, an unusual cause of recurrent vaginal discharge

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.

Transvaginal Migration of Ventriculoperitoneal Shunts in Children: Review of Literature

Ventriculo-peritoneal shunt placement is the most commonly performed procedure for the treatment of hydrocephalus. The complication of migration of the distal ventriculo-peritoneal shunt is one of the many complications that occur after ventriculo-peritoneal shunt placement. The migration of the ventriculo-peritoneal shunt through the vagina is infrequently reported in children. The aim of this review is to help all the providers caring for children with ventriculo-peritoneal shunts to identify issues early when encountered with this complication and thus limit morbidity and mortality. We reviewed all cases of migration of ventriculo-peritoneal shunt through the vagina in children less than 18 years of age that were published in the literature using PubMed, Google Scholar, Web of Science, and Cochrane Library. A total of 11 articles met the eligibility criteria and were included in this review among the 93 articles obtained with title and abstract screening. Previous non-shunt-related abdominal operations and shunt revisions are consistent risk factors in all cases. We did not recognize specific approaches to catheter placement or management that could have prevented this complication. Ventriculitis necessitating shunt removal and therapies requiring additional procedures and prolonged hospitalization are the major consequences identified. Awareness of this unusual complication is very important among health care providers such as emergency care health providers who are likely to be the first to encounter these children on initial presentation.

Migration of Ventriculoperitoneal Shunt to the Uterus in a Child: A Case Report

BACKGROUND

A ventriculoperitoneal shunt (VPS) is usually placed inside the peritoneal cavity for cerebrospinal fluid drainage. Rarely, it can migrate to various pelvic visceral organs. Inside the pelvis, the distal end of the shunt can perforate anywhere from the uterus or adnexa to the vulva, and migration through the uterus is extremely rare.

CASE

A three-and-a-half-year-old girl presented with a cerebrospinal fluid leak through the vagina after uterine perforation by a VPS. The diagnosis was made with an ultrasound. Her symptoms resolved after revision surgery.

CONCLUSION

In a patient with a VPS in situ, presenting with a watery fluid leak through the vagina, perforation of the fornix or uterus must always be kept in mind. Timely diagnosis and intervention can result in the prevention of complications.

Vaginal Extrusion of a Ventriculoperitoneal Shunt: A Case Report and Review of Literature

BACKGROUND

Ventriculoperitoneal shunting is the most common treatment for hydrocephalus (excessive cerebrospinal fluid accumulation in the brain), but has the potential for serious complications such as shunt migration. Potential migration sites include the lateral ventricle mediastinum, gastrointestinal tract, abdominal wall, bladder, vagina, and scrotum.

CASE

Here, we present a rare case of vaginal extrusion of a ventriculoperitoneal shunt.

SUMMARY AND CONCLUSION

Neurosurgeons and gynecologists should be aware of the potential occurrence of this rare complication.
