Recurrent pneumonia caused by transdiaphragmatic erosion of a ventriculoperitoneal shunt into the lung. Case report

Lung destruction secondary to intrapulmonary migration of a ventriculoperitoneal shunt catheter: report of an unusual case and literature review

Ventriculoperitoneal shunt placement for the treatment of hydrocephalus is one of the most common pediatric neurosurgical procedures. Complications, including infections, catheter obstruction, shunt breakdown, and hemorrhage, have been described in the literature. Occasionally, however, uncommon and devastating complications occur. We report a case of a 10-year-old female patient who at birth underwent surgical closure of lumbar myelomeningocele and placement of a CSF shunt at another center. Her neurosurgical follow-up was poor. She presented at our institution with a history of recurrent pneumonia. Control chest X-rays showed a right pulmonary infiltrate with lung retraction and mediastinal shift. Chest and brain CT scans confirmed the intrapulmonary location of the distal catheter tip and ventricular dilation. Surgical shunt revision was performed with removal of the intrapulmonary catheter and placement of a new intraperitoneal catheter. Subsequently, right pneumonectomy was performed with good postoperative recovery of the patient. Intrathoracic migration of the distal catheter of the CSF shunt is an extremely rare complication that may produce severe morbidity. To our knowledge, there have been no previous reports on extensive lung destruction secondary to intrathoracic and intrapulmonary ventriculoperitoneal shunt migration. In patients with CSF shunts and pulmonary symptoms, intrapulmonary catheter migration should be considered.

Shunt-Bronchial Fistula with Coughing Up and Swallowing of Cerebrospinal Fluid: Rare Complication of Ventriculopleural Shunt

BACKGROUND

Erosion of the distal catheter into lung parenchyma is an extremely rare complication of ventriculopleural shunt placement.

CASE DESCRIPTION

We report a 51-year-old woman with a history of parasagittal meningioma invading the sagittal sinus who presented with recurrent pneumonia after placement of a ventriculopleural shunt. A nuclear study revealed accumulation of radiotracer material sequentially in the right hemithorax, trachea, mainstem bronchi, stomach, and bowel. The ventriculopleural shunt had eroded into the patient's lung parenchyma, with the effect of cerebrospinal fluid draining into the respiratory system and then being coughed up and swallowed into the gastrointestinal system.

CONCLUSION

Surgeons should be aware of the potential complication of a ventriculopleural shunt eroding through the lung parenchyma to cause a shunt-bronchial fistula with persistent coughing and recurrent pneumonias. Shuntogram nuclear imaging may be useful in the diagnosis of the complication.

Case report of migration of 2 ventriculoperitoneal shunt catheters to the scrotum: Use of an inguinal incision for retrieval, diagnostic laparoscopy and hernia repair

•

A ventriculoperitoneal shunt catheter migrated through an inguinal hernia into the scrotum.

•

A single incision was used to for diagnostic laparoscopy, catheter removal and hernia repair.

•

Prompt surgical removal of fractured shunt catheters is recommended to prevent organ injury.

Backgroud

Ventriculoperitoneal shunts are commonly used in the treatment of hydrocephalus, and catheter migration to various body sites has been reported. Pediatric and general surgeons are asked on occasion to assist with intraabdominal access for these shunts, particularly when there may be extensive adhesions or other complicating factors.

Methods

We describe a case in which an old shunt catheter was never removed from the abdomen, and it migrated through an inguinal hernia into the scrotum. The catheter became entangled and fibrosed to the testicle. A second and more recent shunt catheter was also in the scrotum. A single incision in the inguinal region was used to remove both shunt catheters, repair the inguinal hernia and perform diagnostic laparoscopy to assist in placing a new ventriculoperitoneal shunt.

Results

Prompt surgical removal is recommended for catheters remaining in the abdomen after ventriculoperitoneal shunt malfunction. These catheters may cause injury to the testicle, or possibly other intraabdominal organs. General or pediatric surgical consultation should be obtained for lost catheters or inguinal hernias.

Conclusion

In the case of an inguinal hernia containing a fractured shunt catheter, the hernia sac can be used to remove the catheter, repair the hernia and gain laparoscopic access to the abdomen to assist with shunt placement.

A Subglandular Breast Cerebrospinal Fluid Pseudocyst Following Postsurgical Shunt Migration

Cerebrospinal fluid (CSF) drainage catheters have been associated with numerous complications in various anatomic locations, because of migration, infection, and obstruction. However, breast-related CSF shunt complications tend to occur infrequently or have seldom been reported in the empirical literature. Therefore, a case is presented detailing a breast pseudocyst caused by migration and subsequent coiling of a ventriculoperitoneal shunt in the right breast pocket. To the best of the authors’ knowledge, this is the first case that has been reported in the peer-reviewed literature of a pseudocyst resulting from a CSF drainage catheter coiling around the breast implant post pancreaticoduodenectomy. Moreover, this case highlights the importance of cross-disciplinary procedural awareness, particularly in regards to breast, ventriculoperitoneal shunt, and pancreatic procedures.

Rare complication of ventriculoperitoneal shunt. Early onset of distal catheter migration into scrotum in an adult male: Case report and literature review

•

Cases of scrotal migration of distal catheter in adults are rare.

•

There have been no reports for scrotal migration in adults at an early onset.

•

Early detection of migration of distal catheter prevents shunt malfunction.

•

Prompt surgical management of catheter repositioning is recommended.

Introduction

The role of shunt placement is to divert cerebrospinal fluid from within the ventricles to an alternative location in the setting of hydrocephalus. One of the rare shunt complications is distal catheter migration, and various body sites have been reported, including the scrotum. Although cases of scrotal migration of distal catheter have been reported in pediatric patients, cases in adult patients are rare due to obliterated processus vaginalis. Furthermore, there has not been a case reported for scrotal migration in an adult at an early onset.

Presentation of case

65-year-old male underwent shunt placement for normal-pressure hydrocephalus-like symptoms. On post-operative day seven patient developed right testicular edema, for which ultrasound was performed, revealing hydrocele along with the presence of distal catheter in the scrotum. On post-operative day nine patient underwent distal catheter trimming via laparoscopic approach with general surgery, with post-operative imaging showing satisfactory location of distal catheter in the peritoneal cavity.

Discussion/Conclusion

Early onset of distal catheter migration into scrotum in an adult male is a unique case, as most cases are reported in pediatric patients, and it is the first case reported in the English literature to have occurrence at an early onset during the peri-operative period. As our case demonstrates, early occurrence and detection of scrotal migration of the distal catheter prevent shunt malfunction. Prompt surgical management of catheter repositioning is therefore recommended to avoid the risk of further complications.

Protrusion of a peritoneal catheter via abdominal wall and operated myelomeningocele area: a rare complication of ventriculoperitoneal shunt

BACKGROUND

Ventriculoperitoneal shunting is mostly used in the treatment of hydrocephalus, and many complications have been reported with this method. These complications include obstruction, mechanical shunt failure, infection, and abdominal complications. Abdominal complications include intestinal obstruction, volvulus, peritonitis, peritoneal cyst, cerebrospinal fluid ascites, as well as migration of the distal catheter via the intestinal tract, umbilicus, scrotum, and vagina. Various mechanisms have been suggested with regards to the catheter migration.

CASE REPORT

We present a case of a 21-month-old female patient who had myelomeningocele at birth. She underwent repair of the myelomeningocele at the age of 10 days. After 4 months, cranial computed tomography revealed hydrocephalus, and ventriculoperitoneal shunt was placed. Because of shunt dysfunction, a new ventriculoperitoneal shunt system was installed at the age of 12 months. Eight months later, her mother noticed the protrusion of peritoneal catheter via abdominal wall and repaired myelomeningocele area. Revision of the lower end of the shunt was done, and myelomeningocele area was repaired again.

CONCLUSION

We report a unique patient with the protrusion of the distal catheter through repaired myelomeningocele area and abdominal wall in the lumbar region.
