BACKGROUND When ventriculoperitoneal (VP) shunts and umbilical hernias coexist in the same patient, unique complications can occur. Typically, these are readily identified problems such as cerebrospinal fluid (CSF) fistulas or entrapment of the peritoneal catheter in the hernia. The authors present cases of two children whose VP shunt dysfunction resolved after repair of their umbilical hernias. OBSERVATIONS The authors present two cases of infant patients with shunted hydrocephalus and umbilical hernias. In both cases, the patients presented with distal shunt malfunctions not due to infection. Their shunt function improved once the umbilical hernia was repaired by pediatric surgery. Neither has required shunt revision since umbilical hernia repair. LESSONS Although there are case reports of VP shunts eroding through the umbilicus, developing CSF fistulas, or becoming trapped inside umbilical hernias, there is no case of VP shunt dysfunction caused by just the presence of an umbilical hernia. The authors suspect that the catheter may intermittently enter and exit the hernia. This may cause intermittent obstruction of the distal catheter, or inflammation in the hernia may occur that limits CSF absorption.

✓ The authors describe a relationship between the presence of distal shunt catheter side-wall slits and distal catheter obstruction in a single-surgeon series of ventriculoperitoneal (VP) shunt revisions. Between 1985 and 1996, 168 operations for VP shunt revision were performed by the senior author (J.W.C.) in 71 patients. Indications for shunt revision included obstruction in 140 operations; overdrainage or underdrainage requiring a change of valve in 17 operations; inadequate length of distal shunt tubing resulting in the distal end no longer reaching the peritoneum in five operations; the ventricular catheter in the wrong ventricle or space, requiring repositioning in five operations; and a disconnected or broken shunt in one operation. Of the 140 instances of shunt obstruction, the blockage occurred at the ventricular end in 108 instances (77.1%), the peritoneal end in 17 (12.1%), the ventricular and the peritoneal end in 14 (10%), and in the valve mechanism (not including distal slit valves) in one (0.8%). Thus, the peritoneal end was obstructed in 31 (22.1%) of 140 cases of shunt malfunction. In every case in which the peritoneal end was obstructed, some form of distal slit was found: either a distal slit valve in an otherwise closed catheter or slits in the side of an open catheter. No instances were found of distal peritoneal catheter obstruction when the peritoneal catheter was a simple open-ended tube with no accompanying side slits (0 of 55). It is concluded that side slits in the distal peritoneal catheters of VP shunts are associated with a greater incidence of distal shunt obstruction.

Proximal migration of the distal end of a ventriculoperitoneal shunt has been observed much more rarely than other numerous shunt-related complications. Subgaleal migration of the peritoneal end is one of the samples. In the preset report we have discussed a case of subgaleal migration of the peritoneal end detected as a result of the examinations performed for shunt dysfunction. There was ventricular dilatation on CT scan of the brain. X-ray examinations confirmed proper ventricular catheter and shunt valve placement but a complete migration of distal (peritoneal) catheter into the subgaleal space. Then the patient’s shunt was revised. When our case and the literature were examined, we observed that this complication was frequently encountered during the first postoperative months, in the pediatric ages and in patients with advanced hydrocephalus. Besides, we have detected that the peritoneal catheters had tendency to migration into the subgaleal tissues similar to pre-insertion forms of the preoperatively original packages.

The ventriculoperitoneal (VP) shunt is a common procedure in pediatric neurosurgery that carries a risk of complications at cranial and abdominal sites. We report on the case of a child with shunt infection and malfunction. The peritoneal catheter was tethered within the abdominal cavity, precluding its removal. Subsequently, laparoscopic exploration identified a knot at the distal end of the peritoneal catheter around the omentum. A new VP shunt was inserted after the infection was healed. This type of complication occurs rarely, so there are a limited number of case reports in the literature. This report is complemented by a literature review.

Small-bowel ischemia and necrosis due to knotting of the peritoneal catheter is an extremely rare complication related to a ventriculoperitoneal shunt (VPS). A 3-month-old girl, with a history of Chiari II malformation and myelomeningocele (MM) after undergoing right occipital VPS insertion and MM repair at birth, presented to the emergency department with a high-grade fever. Examination of a CSF sample obtained via shunt tap raised suspicion for the presence of infection. Antibiotic therapy was initiated, and subsequently the VPS was removed and an external ventricular drain was placed. Intraoperatively, as attempts at pulling the distal catheter from the scalp incision were met with resistance, the distal catheter was cut and left in the abdomen while the remainder of the shunt system was successfully removed. While the patient was awaiting definitive shunt revision surgery to replace the VPS, she developed abdominal distension due to small-bowel obstruction. An emergency exploratory laparotomy revealed a knot in the distal catheter looping around and strangulating the distal ileum, causing small-bowel ischemia and necrosis in addition to the obstruction. A small-bowel resection with ileostomy was performed, with subsequent placement of ventriculoatrial shunt for treatment of hydrocephalus. The authors report this exceedingly rare clinical scenario to highlight the fact that any retained distal catheter must be carefully managed with immediate abdominal exploration to remove the distal catheter to avoid bowel necrosis as pulling of a knotted peritoneal catheter may strangulate the bowel and cause ischemia, with significant clinical morbidity and possible mortality.

Background: Ventriculoperitoneal (VP) shunt failures in adult patients are common and subject patients to multiple surgeries and a decreased quality of life. A prospective cohort Shunt Outcomes Quality Improvement (ShOut-QI) initiative was implemented to reduce shunt failure incidence through neuronavigation-assisted proximal catheter insertion and laparoscopy-guided distal catheter anchoring over the liver dome to drain CSF away from the omentum. Methods: “Pre-ShOut” and “Post-ShOut” groups of patients included those with and without neuronavigation/laparoscopy, respectively for insertion of a new VP shunt. The primary outcome was shunt failure which was defined as any return to surgery for shunt revision as determined with a standardized clinical and radiology follow-up protocol. Results: 244 patients (97 Pre-ShOut, 147 Post-ShOut), mean age 73 years, were enrolled over a 7-year interval and observed for a mean duration of 4 years after shunt insertion. Neuronavigation improved proximal catheter placement accuracy by 20% (p<.001), and shunt failure occurred in 57% vs 23% in the Pre-ShOut and Post-ShOut groups, respectively (p=.008), representing a 53% relative risk reduction in the incidence of shunt failure. Conclusions: Adult shunt failure incidence may be significantly reduced by improving the accuracy of proximal catheter placement with neuronavigation and reducing the risk of distal catheter failure with laparoscopic-guided placement.

BACKGROUND Among the known complications of ventriculoperitoneal (VP) shunts, subcutaneous or subgaleal migration of distal catheters is rare. Prior case reports have proposed several risk factors, including inadequate fixation of the shunt device, presence of a large subgaleal space filled with cerebrospinal fluid (CSF), and repetitive flexion/extension movement of the head producing a “windlass effect.” Tight coiling of a distal catheter around the valve without a large subgaleal space has not been reported. OBSERVATIONS The patient was born prematurely and underwent VP shunt placement for posthemorrhagic ventricular dilatation at 3 months of age with reassuring postoperative imaging. At approximately 3 years of age, shunt radiography and head computed tomography unexpectedly showed excess tubing coiled extracranially around the shunt valve. The patient did not exhibit any clinical symptoms of shunt malfunction and underwent an uneventful revision of the VP shunt system. No CSF-filled subgaleal space was observed intraoperatively. LESSONS Distal catheter migration can occur without the clear presence of a subgaleal CSF collection and symptoms of acute hydrocephalus. Appropriate fixation of the shunt system using nonabsorbable stitches is recommended to prevent catheter migration caused by the windlass effect.

OBJECTIVE Cerebrospinal fluid (CSF) shunting in idiopathic intracranial hypertension (IIH) is associated with high complication rates, primarily because of the technical challenges that are related to small ventricles and a large body habitus. In this study, the authors report the benefits of a standardized protocol for CSF shunting in patients with IIH as relates to shunt revisions. METHODS This was a retrospective study of consecutive patients with IIH who had undergone primary insertion of a CSF shunt between January 2014 and December 2020 at the authors’ hospital. In July 2019, they implemented a surgical protocol for shunting in IIH. This protocol recommended IIH shunt insertion by neurosurgeons with expertise in CSF disorders, a frontal ventriculoperitoneal (VP) shunt with an adjustable gravitational valve and integrated intracranial pressure monitoring device, frameless stereotactic insertion of the ventricular catheter, and laparoscopic insertion of the peritoneal catheter. Thirty-day revision rates before and after implementation of the protocol were compared in order to assess the impact of standardizing shunting for IIH on shunt complications. RESULTS The 81 patients included in the study were predominantly female (93%), with a mean age of 31 years at primary surgery and mean body mass index (BMI) of 37 kg/m2. Forty-five patients underwent primary surgery prior to implementation of the protocol and 36 patients after. Overall, 12 (15%) of 81 patients needed CSF shunt revision in the first 30 days, 10 before and 2 after introduction of the protocol. This represented a significant reduction in the early revision rate from 22% to 6% after the protocol (p = 0.036). The most common cause of shunt revision for the whole cohort was migration or misplacement of the peritoneal catheter, occurring in 6 of the 12 patients. Patients with a higher BMI were significantly more likely to have a shunt revision within 30 days (p = 0.022). CONCLUSIONS The Birmingham standardized IIH shunt protocol resulted in a significant reduction in revisions within 30 days of primary shunt surgery in patients with IIH. The authors recommend standardization for shunting in IIH as a method for improving surgical outcomes. They support the notion of subspecialization for IIH shunts, the use of a frontal VP shunt with sophisticated technology, and laparoscopic insertion of the peritoneal end.

Abstract The ventriculo-peritoneal (VP) shunt surgery in resource constrained centre still remains, most common form of treatment for hydrocephalus. The V. P. shunt complications can occur along entire course of shunt, distal complications are obstruction of catheter, cerebrospinal fluid ascites, abscess and ulceration of skin. However, total cranial migration and getting coiled in subgaleal space, of peritoneal catheter end is very rare occurrence and is reported in only seven cases as isolated case- report in western literature, further more rare is associated extrusion of ventricular catheter and rarer is subgaleal coiling of both peritoneal and ventricular end. Author reports a rare and unique case of complete migration of peritoneal catheter into subgaleal space in a 2-year old boy associated, with partial extrusion of ventricular end, the child was also given electric stimulation by untrained physiotherapist along the shunt tract, which might have facilitated cranial migration of distal catheter in our case. Pertinent literature is briefly reviewed

Associated Symptoms

A complication of ventriculoperitoneal (VP) shunting is overdrainage or overshunting of cerebrospinal fluid, which can cause formation of hygroma but in rare cases also cervical myelopathy at a later stage. In this article, we describe a very late complication of VP shunting. We present a 75-year-old man, previously given a VP shunt at the age of 46, who developed a progressive gait disturbance and ataxia of the limbs after 27 years. MRI showed a cervical stenosis and myelopathy as a result of venous engorgement due to chronic overshunting of the VP shunt. Revision of the VP shunt resulted in complete resolution of his neurological symptoms and the cervical myelopathy. Cervical myelopathy due to chronic overshunting is a rare and potentially very late complication of a VP shunt. Our case underlines the importance of awareness of this complication while proper treatment can reverse the associated symptoms fully.

Abdominal Pseudocyst

Abstract Background Abdominal cerebrospinal fluid (CSF) pseudocyst is an uncommon but important complication of ventriculoperitoneal (VP) shunts. While individual articles have reported many cases of abdominal CSF pseudocyst following VP shunts, no case of a hemorrhagic abdominal pseudocyst after VP shunts has been reported so far. Case presentation This article reports a 68-year-old woman with a 4-month history of progressive abdominal pain and distention. She denied any additional symptoms. A VP shunt was performed 15 years earlier to treat idiopathic normal pressure hydrocephalus and no other abdominal surgery was performed. Physical examination revealed an elastic palpable mass in her right lower abdomen, which was dull to percussion. Abdominal computed tomography (CT) scan indicated a large cystic collection of homogenous iso-density fluid in the right lower abdominal region with clear margins. The distal segment of the peritoneal shunt catheter was located within the cystic mass. Abdominal CSF pseudocyst was highly suspected as a diagnosis. Laparoscopic cyst drainage with removal of the whole cystic mass was performed, 15-cm cyst which found with thick walls and organized chronic hematic content. No responsible vessel for the cyst hemorrhage was identified. No further shunt revision was placed. Histological examination showed that the cyst wall consisted of outer fibrous tissue and inner granulation tissue without epithelial lining, and the cystic content was chronic hematoma. The patient had an uneventful postoperative course and remained asymptomatic for 8-mo follow-up. Conclusion To the best of our knowledge, this is the first report of hemorrhagic onset in the abdominal pseudocyst following VP shunt. Such special condition can accelerate the appearance of clinical signs of the abdominal pseudocyst after VP shunts, and its mechanisms may be similar to the evolution of subdural effusion into chronic subdural hematoma (CSDH).
