REVIEW
Yun Ho Lee, Young Sub Kwon, Kook Hee Yang
Multiloculated hydrocephalus (MLH) is a condition in which patients have multiple, separate abnormal cerebrospinal fluid collections with no communication between them. Despite technical advancements in pediatric neurosurgery, neurological outcomes are poor in these patients and the approach to this pathology remains problematic especially given individual anatomic complexity and cerebrospinal fluid (CSF) hydrodynamics. A uniform surgical strategy has not yet been developed. Current treatment options for MLH are microsurgical fenestration of separate compartments by open craniotomy or endoscopy, shunt surgery in which multiple catheters are placed in the compartments, and combinations of these modalities...

BACKGROUND: Patients with an external ventricular drain (EVD) may not be readily mobilized because of concerns of catheter dislodgment and/or inappropriate cerebrospinal fluid drainage. Delayed mobilization may result in longer hospital stays and an increased risk for complications related to immobility. We aimed to determine the safety, feasibility, and outcome of an EVD mobilization protocol in patients with subarachnoid hemorrhage (SAH). METHODS: A multidisciplinary group developed a formal algorithm for the mobilization of patients with SAH with EVDs...

PURPOSE: We have discussed the diagnosis and treatment approaches in patients with discontinued (disconnected or fractured) ventriculoperitoneal (VP) shunts that caused mechanical dysfunction. METHODS: Between 2006 and 2016, VP shunt surgery was performed on 1357 pediatric patients in our clinic. In follow-up examinations, we retrospectively reviewed patients who underwent revision surgery. Except for diagnosis of discontinued VP shunt, by excluding revision-surgery patients, only those patients who underwent surgical treatment owing to discontinued (fracture or disconnection) catheter were included in the study...

Ventriculoperitoneal (VP) shunting remains invaluable in the management of hydrocephalus. It is a common procedure that can be complicated by shunt malfunction due to infection, blockage and disconnection. Spontaneous peritoneal catheter knot formation causing CSF flow obstruction is a rare phenomenon. We present a case of a 12years old boy with spontaneous knot formation in the peritoneal catheter causing VP shunt obstruction and hydrocephalus.

OBJECTIVE: Peripherally inserted central catheter (PICC) use continues to increase, leading to the development of a blind bedside technique (BST) for placement. The aim of our study was to compare the BST with the fluoroscopically guided technique (FGT), with specific regard to catheter tip position (CTP). MATERIALS AND METHODS: One hundred eighty patients were randomized to either the BST or the FGT. All procedures were done by the same interventional team and included postprocedural chest X-ray to assess CTP...

BACKGROUND: Prevalent hemodialysis patients with vascular access consisting of a central venous catheter (CVC) are continuously increasing over the years. Improvement in evolution and CVC placement procedures represents therefore an essential tool to enhance performance and reduce intraoperative and long-term CVC complications. Internal jugular vein (IJV) catheterization techniques are different according to ultrasound probe position in relation to vein axis and to needle direction in relation to ultrasound beam...

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...

Catheter migration and omental wrap are the most common causes of catheter malfunction, which usually result in catheter removal or replacement. The conventional open surgery for catheter reposition has many disadvantages. A new tunnel is needed throughout the procedure of catheter replacement causing more pain and frustration to the patients. Another drawback is that the incidence of catheter migration after conventional catheter reposition surgery is still as high as it was before the procedure. Wang's forceps, an instrument commonly used in our peritoneal dialysis center, is easy and effective in catheter insertion and fixation...

AIM: Catheter malfunction is the main reason for early peritoneal dialysis (PD) technique failure. This study aimed to evaluate the effect of a new surgery technique with catheter fixation to the lower abdominal wall combined with straight upward tunnel and low implant position in reducing catheter malfunction. METHODS: Patients with end stage renal disease who received PD in our center from January 2013 to December 2015 were involved in this study. They were randomly divided into 3 groups according to surgical technique: traditional open surgery group, modified open surgery group and modified open surgery with catheter fixation group...

Although the Codman-Hakim programmable valve is one of most popular shunt systems used in the clinical practice for the treatment of hydrocephalus, malfunctions related with this system have been also reported which lead to underdrainage or overdrainage of the cerebrospinal fluid. While obstruction of the ventricular catheter by tissue materials or hematoma and catheter disconnection are relatively common, the malfunction of the valve itself is rare. Herein, we report on a rare case of shunt overdrainage caused by displacement of the pressure control cam after pressure adjustment...

Peritoneal dialysis (PD) is limited mainly by a higher technique failure rate as compared to hemodialysis (HD), catheter malfunction being an important reason. Intra- and extra-peritoneal catheter configuration may be associated with mechanical and infectious complications affecting method survival. We report our experience with two extra-peritoneal catheter configurations: the straight and the swan-neck (SN) catheters. A total of 85 consecutive patients, 58 males and 27 females were included in the study. Among them, 26 were diabetics; 52 were treated with automated PD (APD) and 33 with continuous ambulatory PD (CAPD)...

Intrathecal baclofen is now an admitted treatment of generalized and disabling spasticity. Technical incidents of the device remain frequent, mainly due to catheter problems. Consequences can be abrupt with life-threatening withdrawal syndrome or progressive with spasticity reappearance. In case of progressive withdrawal syndrome, the assessment process has to be meticulous to find the cause of inefficiency and to avoid useless revision surgery. This assessment includes medical examination, radiographs, intrathecal baclofen bolus, after what, if no conclusion can be drawn, a more invasive imaging exam has to be performed...

BACKGROUND: Central venous access devices (CVADs) play an important role in the management of pediatric oncology patients; unfortunately, they are also associated with potentially serious complication rates. We hypothesized that, despite the significantly different disease courses typical of acute lymphoblastic leukemia and acute myelogenous leukemia, there would be identifiable risk factors for premature CVAD removal. METHODS: We retrospectively studied clinical characteristics and procedure records for all patients admitted with a leukemia diagnosis at our institution from May 2009 to July 2014...

BACKGROUND: A totally implantable venous access device (TIVAD) provides reliable, long-term vascular access and improves patients' quality of life. The wide use of TIVADs is associated with important complications. A meta-analysis was undertaken to compare the internal jugular vein (IJV) with the subclavian vein (SCV) as the percutaneous access site for TIVAD to determine whether IJV has any advantages. METHODS: All randomized controlled trials (RCTs) and cohort studies assessing the two access sites, IJV and SCV, were retrieved from PubMed, Web of Science, Embase, and OVID EMB Reviews from their inception to December 2015...

PURPOSE: Over the past two decades, continuous ambulatory peritoneal dialysis has emerged as the first-choice dialysis modality in children awaiting for transplantation. Despite the improvements observed in catheter survival over the past several years, the obstruction is one of the reasons for immediate catheter non-function. This study assessed usefulness of ultrasound (US) in visualizing the obstruction of chronic peritoneal dialysis (CPD) catheter and identifying the etiology. MATERIALS AND METHODS: Between January 2000 and November 2012, 38 patients (20 M, 18 F) were treated with CPD and examined with US...

Neurosurgical ventricular shunts inserted to treat hydrocephalus experience a cumulative failure rate of 80 % over 12 years; obstruction is responsible for most failures with a majority occurring at the proximal catheter. Current diagnosis of shunt malfunction is imprecise and involves neuroimaging studies and shunt tapping, an invasive measurement of intracranial pressure and shunt patency. These patients often present emergently and a delay in care has dire consequences. A microelectromechanical systems (MEMS) patency sensor was developed to enable direct and quantitative tracking of shunt patency in order to detect proximal shunt occlusion prior to the development of clinical symptoms thereby avoiding delays in treatment...
