Scrotal swelling due to migration of the abdominal catheter of a cyst-peritoneal shunt

Scoliosis due to scar contracture caused by infection after cyst-peritoneal shunt: a case report and literature review

BACKGROUND

Cyst-peritoneal (CP) shunt is one of the most common methods for the treatment of intracranial arachnoid cysts (ACs). Infection is a common postoperative complication. We report a patient with scoliosis due to scar contracture caused by infection after CP shunt.

CASE DESCRIPTION

A 12-year-old boy underwent CP shunt surgery for the left frontoparietotemporal AC when he was 2 years old. At the age of 7 years, he underwent a shunt catheter removal procedure because of the infection caused by the fistula leading from the subcutaneous tunnel to the body surface. However, contracture of the subcutaneous scar from fistula infection caused scoliosis and limited range of motion of the right arm. At the age of 12, the patient received scar lysis and his symptoms improved.

CONCLUSION

We presented the first case of scoliosis due to scar contracture caused by infection after CP shunt. In this case, timely release of scar tissue can effectively correct scoliosis and limb movement limitation.

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.
