Abstract
BACKGROUND At Red Cross War Memorial Children's Hospital (RCCH), it is the preferred practice to use non-ventriculoperitoneal (non-VP) shunts when the peritoneum is ineffective or contraindicated for cerebrospinal fluid (CSF) diversion and when endoscopy is not an option. The objective of this study is to evaluate the clinical course of patients having undergone these procedures. METHOD A single-centre retrospective review at RCCH wherein 43 children with a total of 59 episodes of non-VP shunt placement over a 12-year period were identified for inclusion. RESULTS Twenty-five ventriculoatrial (VA) and 32 ventriculopleural (VPL) shunts were analysed with a median age at insertion of 2.9 (0.3-14.9) and 5.3 years (0.5-13.4), respectively. The median number of previous shunt procedures prior to VA or VPL shunt insertion was 6.0 (2-28) versus 4.5 (2-17), respectively. Three VA (12.0%) and three VPL (9.4%) shunt patients were lost to follow-up. Of those remaining, 10 VA shunts (45.5%) compared to 19 (65,5%) VPL shunts required revision. One ventriculovesical shunt and one ventriculocholecystic shunt were placed in the same patient after 21 and 25 shunt-related procedures, respectively, and both were revised within 3 weeks of insertion. Median shunt survival was 8 months longer for the VA compared to the VPL shunts, being 13.5 (0-67) and 5 months (0-118), respectively. Complications for VA shunts were low, with the overall shunt sepsis rate in the VA group at 4% (n = 1) compared to 15.6% (n = 5) in the VPL group. CONCLUSION Our findings support that VA and VPL shunts are acceptable second-line options in an already compromised group of patients where safe treatment options are limited, provided attention is paid to the technical details specific to their placement.

[PMID: 38386079 PMCID: PMC10884045 DOI: 10.1007/s00701-024-05985-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Accepted: 01/15/2024] [Indexed: 02/23/2024]
Abstract
PURPOSE CSF diversion is a recognised intervention in idiopathic intracranial hypertension (IIH), particularly in the presence of vision-threatening papilledema. Although ventriculo-atrial (VA) shunt insertion is a routine neurosurgical procedure, ventriculoperitoneal and lumboperitoneal shunts have been mostly used in this particular indication. This study aims to look at a single centre's experience with VA shunts in idiopathic intracranial hypertension (IIH). METHODS Retrospective case series with a review of electronic records over a 10-year period; exclusion criteria were duplication of same shunt insertion, no VA shunt insertion, paediatric patients and indication other than IIH. Notes were reviewed for demographics, shunt survival (defined by time prior to revision) and reasons for revision. RESULTS Eight VA shunt procedures were identified in 6 patients (mean age at insertion 34 ± 10 years) with a mean follow-up of 58 ± 25 months. All shunts were secondary procedures; 2 revisions from lumbo-pleural, 2 from ventriculopleural, 2 from ventriculoatrial and one each from ventriculoperitoneal and combined lumbo-/ventriculoperitoneal. At 50 months, 75% of VA shunts had survived, compared to only 58.3% of VPleural shunts in patients with IIH. Revisions were required due to acute intracranial bleed (1 case)-revised at day 1, and thrombus at distal site (1 case)-revised at day 57. Both shunts were later reinserted. From the latest clinic letters, all patients had their treatment optimised with this procedure, although only two patients had documented resolved papilloedema post-procedure. CONCLUSIONS Ventriculo-atrial shunts are a safe and efficacious alternative option for CSF diversion in IIH. In this series, only 1 shunt was revised for a VA shunt-specific complication.

The Long-Term Patency of the Internal Jugular Vein and the Common Facial Vein as Entrance Sites for Venous Access in Ventriculoatrial Shunts: A Comparative Analysis from a Single-Center Study. World Neurosurg 2024; 182:e652-e656. [PMID: 38065357 DOI: 10.1016/j.wneu.2023.12.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 12/01/2023] [Accepted: 12/02/2023] [Indexed: 01/01/2024]
Abstract
OBJECTIVE The ventriculoatrial (VA) shunt is a surgical intervention used to manage hydrocephalus, although it is less often utilized compared to the ventriculoperitoneal (VP) shunt or endoscopic third ventriculostomy. Placement of the distal catheter typically involves the utilization of either the common facial vein (CFV) or the internal jugular vein (IJV), 2 frequently employed options for venous access. This study aims to determine whether there is a statistically significant difference between the long-term patency (2 years) of the distal end of the VA shunt of these 2 options. METHODS A retrospective cohort analysis was conducted of patients who received VA shunt surgeries with the employment of the CFV or IJV as access veins at Rajavithi Hospital in Thailand between January 2015 and December 2020. The analysis focused on long-term patency and potential complications. RESULTS The study comprised a total of 42 participants. Twenty-six (61.9%) individuals underwent ventriculoatrial (VA) shunt surgery via the CFV, while the other 16 (38.1%) underwent the same procedure using the IJV. Neither of the 2 groups required shunt revision due to distal catheter malfunction. Most cases exhibited no significant complications apart from a single instance of shunt system infection. CONCLUSIONS In VA shunt surgery, both the CFV and IJV can be used as venous access sites for the right atrium because there is no discernible difference between their complications or long-term patency. Anatomical considerations, patient-specific characteristics, and the surgeon's preference should all be considered when choosing the venous access location for the placement of a VA shunt.

Abstract
BACKGROUND Ventriculoatrial shunt (VAS) is considered the second option for treating hydrocephalus, but there remains a lack of robust evidence regarding its complications profile. PURPOSE Evaluate the complications associated with VAS. METHODS Adhering to PRISMA guidelines, the authors searched Embase, PubMed, and Web of Science databases to identify articles reporting on the complications of VAS. Eligible articles were required to report whether complications occurred in a cohort of at least four patients. The extraction process focused on various outcome measures, including overall complications, pulmonary complications, cardiac complications, mortality, shunt revisions, glomerulonephritis, intracranial hemorrhage, and hygroma. Complications were defined as any adverse events related to the procedure, including revisions. RESULTS After retrieving a total of 2828 articles, 53 studies met the predefined criteria, involving 2862 patients. The overall complication rate was estimated at 33 % (95 % CI: 25-42 %), while the long-term complications rate was found to be 49 % (95 % CI: 32-67 %). Among the pediatric population, the complication rate was calculated to be 53 % (95 % CI: 39-68 %). The overall revision rate was estimated at 32 % (95 % CI: 23-41 %), with an infection rate of 5 % (95 % CI: 3-7 %). Notably, in the pediatric group, the infection rate was 10 % (95 % CI: 6-13 %). The random analysis indicated an estimated risk of 0 % for glomerulonephritis, intracranial hemorrhage, hygroma, cardiac complications, pulmonary complications, and shunt-related mortality. CONCLUSION VAS is a safe alternative when ventriculoperitoneal shunting is not feasible. Risk of classic severe complications is minimal. Nevertheless, caution is required when shunting critical patients. Further randomized studies are warranted to establish the ideal shunt for different patients.

Abstract
Intraoperative ultrasonography is an extremely valuable tool for avoidance of complications during neurosurgical procedures, including resection of intracranial and spinal cord tumors, removal of spontaneous intracerebral hemorrhages and arteriovenous malformations, and ventricular access for shunt placements. Nevertheless, application of this highly useful technique may be accompanied by some challenges and difficulties, as well as human errors; thus, it requires specific knowledge and continuous training.

Abstract
Diversion of cerebrospinal fluid is required in many neurosurgical conditions. When a standard ventriculoperitoneal shunt and endoscopic third ventriculostomy are not appropriate options, placement of a ventriculoatrial shunt is a safe, relatively familiar second-line shunting procedure. Herein we reviewed the technical aspects of ventriculoatrial shunt placement using an illustrative case. We focused on the different modalities for inserting and confirming the location of the distal catheter tip. We discussed how to overcome typical difficulties and significant concerns, such as cardiac arrhythmias and venous thrombosis. In addition, we reviewed the current literature for the different complications associated with ventriculoatrial shunt placement.

Abstract
OBJECTIVE As far as the ventriculoatrial shunt placement in children is concerned, the percutaneous approach to the internal jugular vein under ultrasonographic control has been hitherto strongly recommended. Unfortunately, children still represent a challenge, having them peculiar characteristics for which the internal jugular vein cannulation shows some disadvantages. METHODS In this manuscript, we describe a percutaneous placement of ventriculoatrial shunt via right brachiocephalic vein under intraoperative ultrasonographic control. CONCLUSIONS Brachiocephalic vein cannulation in surgery provides notable advantages in paediatric population and it may be considered as the first choice in younger children.
