Background: Ventriculoperitoneal (VP) shunting is a common treatment for hydrocephalus. Complications of VP shunt include infection, malfunction, and hemorrhage. Vascular complications such as pseudoaneurysm are rare, and usually involve the choroid plexus or branches of the external carotid artery. We present the case of a fusiform pseudoaneurysm of the middle cerebral artery arising due to VP shunt insertion. Methods: A 36-year-old female presented with a hypertensive cerebellar hemorrhage and hydrocephalus. This was treated with VP shunt placement with limited dural opening. Three weeks afterward there developed a diffuse intraventricular hemorrhage associated with hemorrhage at the cortical insertion site of the ventricular catheter. CT and catheter angiography revealed a fusiform pseudoaneurysm of the M4 segment of the MCA immediately adjacent to the ventricular catheter. Results: The VP shunt was removed, and the aneurysmal segment was coagulated and occluded. Delayed repeat VP shunt insertion was performed through the same entry point and trajectory via a larger dural opening. Conclusions: Pseudoaneurysm formation secondary to catheter insertion is a rare complication. To our knowledge, this is the second reported case of a cortical branch pseudoaneurysm in an adult. Careful consideration should be given to vascular anatomy when planning shunt insertions, and cruciate dural opening for local cortex visualization may help avoid this complication.

Background: Cerebral pseudoaneurysm formation associated with ventricular catheterization is an exceedingly rare complication that results from direct catheter-induced injury to a vessel. We report a case of intracerebral pseudoaneurysm formation associated with ventricular catheterization in a patient with hydrocephalus following aneurysmal subarachnoid hemorrhage. Case Description: The patient presented with aneurysmal subarachnoid hemorrhage and underwent partial endovascular embolization of the offending wide-necked basilar tip aneurysm with the plan for a Stage 2 stent-assisted coiling after initial recovery. Before discharge, a ventriculoperitoneal shunt (VPS) was placed for postaneurysmal hydrocephalus. Three weeks later, she presented with intraparenchymal and intraventricular hemorrhage. Angiography revealed a cortical aneurysm contiguous to the ventricular catheter of the VPS. She underwent microsurgical excision of the aneurysm, and a new VPS was placed after resolution of the intraventricular hemorrhage. She later underwent the second stage of the treatment and had an excellent neurological recovery to an independent state. Conclusion: Iatrogenic intracerebral pseudoaneurysm formation is an exceedingly rare complication of ventricular catheterization but is associated with significant mortality. Identifying a pseudoaneurysm in this context warrants prompt and definitive treatment with microsurgical or endovascular treatment.

OBJECTIVEProximal malfunction is the most common cause of ventriculoperitoneal (VP) shunt failure in young children. In this study, the authors sought to determine factors that affect the migration rate of ventricular catheters in hydrocephalic children who undergo shunt implantation in the first 3 years of life.METHODSThe authors reviewed the medical records and imaging studies of newly diagnosed and treated hydrocephalic children who were younger than 3 years. Patients who received VP shunt insertion through the parieto-occipital route were not included. In total, 78 patients were found who underwent VP shunt insertion between December 2006 and April 2017. Eighteen patients were excluded due to mortality, short follow-up period (< 1 year), and lack of imaging follow-up. The age, sex, etiology of hydrocephalus, initial length of ventricular catheter, valve type (burr hole vs non–burr hole), time to ventricular catheter migration, subsequent revision surgery, and follow-up period were analyzed. The diagnosis of a migrated ventricular catheter was made when serial imaging follow-up showed progressive withdrawal of the catheter tip from the ventricle, with the catheter shorter than 4 mm inside the ventricle, or progressive deviation of the ventricular catheter toward the midline or anterior ventricular wall.RESULTSSixty patients were enrolled. The mean age was 5.1 months (range 1–30 months). The mean follow-up period was 50.9 months (range 13–91 months). Eight patients had ventricular catheter migration, and in 7 of these 8 patients a non–burr hole valve was used. In the nonmigration group, a non–burr hole valve was used in only 6 of the 52 patients. Six of the 8 patients with catheter migration needed second surgeries, which included removal of the shunt due to disconnection in 1 patient. The remaining 2 patients with shunt migration were followed for 91 and 46 months, respectively, without clinical and imaging changes. The authors found that patient age at catheter insertion, ventricular catheter length, and the use of a burr hole valve were protective factors against migration. After ventricular catheter length and patient age at catheter insertion were treated as confounding variables and adjusted with multivariable Weibull proportional hazards regression, the use of a burr hole valve shunt remained a protective factor.CONCLUSIONSThe use of burr hole valves is a protective factor against ventricular catheter migration when the shunt is inserted via a frontal route. The authors suggest the use of a burr hole valve along with a frontal entry point in hydrocephalic children younger than 3 years to maintain long-term shunt function.

Object. Endoscopically assisted ventricular catheter placement has been reported to reduce shunt failure in uncontrolled series. The authors investigated the efficacy of this procedure in a prospective multicenter randomized trial. Methods. Children younger than 18 years old who were scheduled for their first ventriculoperitoneal (VP) shunt placement were randomized to undergo endoscopic or nonendoscopic insertion of a ventricular catheter. Eligibility and primary outcome (shunt failure) were decided in a blinded fashion. An intention-to-treat analysis was performed. The sample size offered 80% power to detect a 10 to 15% absolute reduction in the 1-year shunt failure rate. The authors studied 393 patients from 16 pediatric neurosurgery centers between May 1996 and November 1999. Median patient age at shunt insertion was 89 days. The baseline characteristics of patients within each group were similar: 54% of patients treated with endoscopy were male and 55% of patients treated without endoscopy were male; 30% of patients treated with and 26% of those without endoscopy had myelomeningocele; a differential pressure valve was used in 51% of patients with and 49% of those treated without endoscopy; a Delta valve was inserted in 38% of patients in each group; and a Sigma valve was placed in 9% of patients treated with and 12% of those treated without endoscopy. Median surgical time lasted 40 minutes in the group treated with and 35 minutes in the group treated without endoscopy. Ventricular catheters, which during surgery were thought to be situated away from the choroid plexus, were demonstrated to be in it on postoperative imaging in 67% of patients who had undergone endoscopic insertion and 61% of those who had undergone nonendoscopic shunt placements. The incidence of shunt failure at 1 year was 42% in the endoscopic insertion group and 34% in the nonendoscopic group. The time to first shunt failure was not different between the two groups (log rank = 2.92, p = 0.09). Conclusions. Endoscopic insertion of the initial VP shunt in children suffering from hydrocephalus did not reduce the incidence of shunt failure.

<p>Ventriculoperitoneal (VP) Shunt is a commonly performed surgical procedure and offers a good result in the treatment of hydrocephalus. In general, 25% of the complication rate of this surgical procedure is abdominal complications. Anal extrusion of a peritoneal catheter is a rare complication ranging from 0.1 to 0.7% of all shunt surgeries. This study presents a rare case of anal extrusion of ventriculoperitoneal shunt in a 1-year-old female child who was asymptomatic. The physical examination revealed swelling and redness along the shunt tract on the retro auricular region, soft abdomen, and no catheter was observed in the anal. This study found several contributing factors affecting the complications in the anal extrusion of a peritoneal catheter, that are thin bowel wall in children and sharp tip and stiff end of VP shunt. The shunt should be disconnected from the abdominal wall, and the lower end should be removed through the rectum by colonoscopy or sigmoidoscopy/proctoscopy or by applying gentle traction on the protruding tube. This study concludes that due to potentially life-threatening consequences and case rarity, thorough anamnesis, physical examination, and objective investigation are needed to determine the appropriate management for anal extrusion of ventriculoperitoneal shunt. </p>

CONTEXT: VP Shunt is most commonly used procedure for hydrocephalus but shunt failure is also the common complication in many patients. Endoscopic third ventriculostomy (ETV) is an accepted procedure for the treatment of obstructive hydrocephalus. The aim of our study is to evaluate the success rate AIM AND OBJECTIVE - of ETV in patients of obstructive hydrocephalus formerly treated by ventriculo-peritoneal (VP shunt) shunt. The failure VP shunt was removed before ETV. MATERIALS AND METHOD: This study was conducted between June 2015 and December 2019 in single unit of our department. Twenty one (n=21) patients were enrolled for this study. All patients were admitted with failure of VP shunt. They were known case of non-communicating hydrocephalus previously operated for VP shunt. Six patients were excluded for ETV because CT/MRI show grossly distorted anatomy of ventricles. Endoscopic third ventriculostomy was attempted in 15 patients, but ventriculostomy was done successfully in 10 patients, rests were treated with revision of VP shunt. All patients in this study were radiologically diagnosed RESULTS: case of hydrocephalus due to aqueduct stenosis. They were experienced VP shunt insertion but there were failure of shunt due to any reason. ETV procedures were done successfully in 10 patients. Out of 10 patients one patient needed shunt insertion due ineffective ETV. Shunt revision was done in 11 patients. There was no serious complication during and after ETV procedures. The follow-up period of patients with successful ETV was 6–60 months. This follow-up was uneventful and peaceful for their parents. ETV can be considered as an alternative treatment for the patients w CONCLUSION: ith VP shunt failure with an acceptable success rate of 80%, although long-term follow-up is needed for these patients.

Background Abdominal access during ventriculoperitoneal (VP) shunt insertion has historically been obtained by neurosurgeons via an open abdominal approach. With recent advances in laparoscopy, neurosurgeons frequently consult general surgery for aid during the procedure. The goal of this study is to identify if laparoscopic assistance improves the overall outcomes of the procedure. Methods This retrospective study included all patients who underwent open or laparoscopic VP shunt placement between September 2012 and August 2020 at our tertiary referral hospital. Patient demographics, comorbidities, prior history of abdominal surgery, open vs. laparoscopic insertion, operation time, and complications within 30 days were obtained. Results Neurosurgery placed 107 shunts using an open abdominal technique and general surgery placed 78 using laparoscopy. The average OR time in minutes was 75.5 minutes for the open cohort and 61.8 for the laparoscopic cohort ( p = 0.006). In patients without a history of abdominal surgery, the average OR time in minutes was 79.4 in the open cohort and 57.1 in the laparoscopic cohort ( p = 0.015). The postoperative shunt infection rate was 10.2% in the open group and 3.8% in the laparoscopic group ( p = 0.077). Discussion Laparoscopic placement of VP shunts is a reasonable alternative to open placement and results in shorter OR times. There is also a trend toward few infections in the laparoscopic placement. There appears to be an advantage with a team approach and laparoscopic placement of the peritoneal portion of the shunt.

Abstract Background Treatment of secondary hydrocephalus due to posterior fossa tumors in these children is still a matter of controversy, although preoperative ventriculo-peritoneal shunt (VP shunt) insertion before tumor excision is widely accepted among neurosurgeons but many attempts are rising to minimize permanent VP shunt insertion and associated complications and introducing third endoscopic ventriculostomy (ETV) as one of the options of 2ry hydrocephalus. Objectives Comparing the post-operative clinical success with resolution of the manifestations and post-operative complications between endoscopic third ventriculostomy and ventriculoperitoneal shunt as different modes of CSF diversion in children with 2ry hydrocephalus due to midline posterior fossa tumors. Methods The following electronic databases were searched from June 2009 to june2019: PubMed, Google scholar search engine. Cochrane database of systematic reviews, EMBASE and science Direct, using the keywords ―hydrocephalus; posterior fossa tumors; pediatrics; ventriculoperitoneal shunt; endoscopic third ventriculostomy‖. Studies were eligible if they contain the target keywords in title or abstract, addressing the Pediatric age group with 2ry hydrocephalus due to de novo posterior fossa tumor manifested by signs of increase the intra cranial tension including persistent headache and vomiting, blurred vision, 6th nerve palsy, papilledema in fundus examination, acute DCL and 2ry hydrocephalus confirmed by brain imaging. Exclusion criteria included studies including age group below 1yr or above 18 yr, or patients with recurrent post fossa tumors and operated before or patients presented by failed previously attempt of CSF diversion. Results: A total of 1255 citations were screened for eligibility,6 studies were included in our systematic review discussing, comparing and evaluating the durability of ETV versus VP shunt in treatment the 2ry hydrocephalusdue to pediatric posterior fossa tumor.. Overall study population reached 474 patients. the overall clinical findings at presentation and postoperative outcomes regarding the clinical findings improvement, radiological improvement and postoperative complications between ETV and VP shunt are compared and showing that ETV should be considered as an alternative procedure to VP shunt in controlling severe hydrocephalus related to posterior fossa tumors to relieve symptoms quickly during the preoperative period when patients should wait for their definite tumor excision. Conclusion The shorter duration of surgery, the lower incidence of morbidity, the absence of mortality, the lower incidence of procedure failure of endoscopic third ventriculostomy as compared to ventriculoperitoneal shunt, and the significant advantage of not becoming shunt dependent make endoscopic third ventriculostomy to be recommended as the first choice in the treatment of pediatric patients with marked obstructive hydrocephalus due to posterior fossa tumors. It is a preliminary, simple, safe, effective, physiological, minimally invasive procedure for the relief of elevated intracranial pressure before direct tumor removal.

This chapter describes the intra-aortic balloon pump (IABP), which is the single most widely used mechanical circulatory assist device available today. Counterpulsation refers to balloon inflation in diastole and deflation in early systole: this results in increased coronary blood flow, left ventricular afterload reduction, and increased end-organ perfusion. Other uses of balloon counterpulsation include refractory ventricular arrhythmias, inability to wean from cardiopulmonary bypass, bridge to intervention in severe/critical aortic stenosis, and refractory pulmonary edema from decompensated heart failure. However, the absolute contraindications for IABP placement are aortic dissection, clinically significant aortic aneurysm, severe peripheral artery disease, significant aortic regurgitation, uncontrolled bleeding, and/or sepsis. The chapter then explains the optimal positioning for IABP. It also looks at complications associated with IABPs. These include thrombocytopenia and vascular complications, such as limb ischemia, bleeding, dissection, and hematoma/pseudoaneurysm formation. The presence of blood in the balloon tubing suggests the possibility of balloon rupture and gas embolism, an extremely uncommon but catastrophic event.

Object Previous studies have shown nutritional benefits of breastfeeding for a child's health, especially for protection against infection. Protective factors in human milk locally and systemically prevent infections in the gastrointestinal as well as upper and lower respiratory tracts. It remains unclear whether breastfeeding protects infants against ventriculoperitoneal (VP) shunt infection. Methods A cohort study was conducted from December 2003 to December 2006 at Children's Hospital Medical Center in Tehran, Iran. A total of 127 infants with hydrocephalus who were treated using a VP shunt in the first 6 months of life were enrolled. Each infant's breastfeeding method was classified as either exclusively breastfed (EBF), combination feedings of breast milk and formula (CFBF), or exclusively formula-fed (EFF). Infants were followed up to determine the occurrence of shunt infection within 6 months after operation. Statistical analysis was performed using survival methods. Results Infants ranged in age from 4 to 170 days at the time of shunt insertion (mean 69.6 days), and 57% were males. Regarding the breastfeeding categories, 57.5% were EBF, 25.2% were CFBF, and 17.3% were EFF. During the follow-up, shunt infection occurred in 16 patients, within 15 to 173 days after shunt surgery (median 49 days). The 6-month risk of shunt infection was 8.5% (95% confidence interval [CI] 4–18%) in the EBF group, 16.5% (95% CI 7–35%) in the CFBF group, and 26.0% (95% CI 12–52%) in the EFF group. There was no statistically significant difference between these 3 groups (p = 0.11). The trend test showed a significant trend between the extent of breastfeeding and the risk of shunt infection (p = 0.035), which persisted even after adjustment for potential confounding variables (hazard ratio = 2.01, 95% CI 1.01–4). Conclusions This study supports the protective effect of breastfeeding against shunt infection during the first 6 months of life and the presence of a dose–response relationship, such that the higher the proportion of an infant's feeding that comes from human milk, the lower the incidence of shunt infection. Encouraging mothers of infants with VP shunts to breastfeed exclusively in the first 6 months of life is recommended.

Abstract BACKGROUND: Placement of an external ventricular drain (EVD) is a commonly performed and often lifesaving procedure. Although hemorrhage is one of the commonest complications associated with the procedure, ventricular catheter–induced vascular injury is rarely reported. OBJECTIVE: To describe 9 cases of EVD-related vascular trauma: 7 arteriovenous fistulas and 2 traumatic aneurysms. METHODS: During a 3-year period, 299 patients had EVDs placed. Eight patients (2.75%), 3 male and 5 female (mean age, 48 ± 20 years), developed vascular lesions associated with EVDs. Six patients developed arteriovenous fistulas and 2 patients developed a traumatic aneurysm. The arterial feeders of 5 superficial draining fistulas arose from the middle meningeal artery, and the arterial feeder of a deep-draining fistula originated from a lenticulostriate artery. One traumatic aneurysm arose from a distal branch of the anterior cerebral artery, and the second from a branch of the superficial temporal artery. Four of the superficial fistulas were treated with transarterial embolization. RESULTS: Two superficial fistulas and the deep-draining fistula resolved spontaneously after EVD removal. The intracranial aneurysm was embolized with Onyx18, and the superficial temporal artery aneurysm was managed conservatively. There were no hemorrhages associated with any of these vascular lesions and no complications after treatment. CONCLUSION: Our data suggest that iatrogenic vascular trauma associated with EVD insertions (2.75%) may be more common than is currently appreciated. Endovascular treatment is effective and may be necessary when these lesions do not resolve spontaneously.
