OBJECTIVE: Surgical management of spinal dysraphism often requires the use of dural substitutes. Amniotic membrane (AM) has drawn the interest of clinicians for its valuable concentration of cytokines and factors capable of promoting wound healing, re-epithelialization, inhibiting fibrosis and regulating angiogenesis. These beneficial qualities could make AM an interesting dural substitute for spina bifida repair. In this study, we describe the use of banked homologous AM as a dural substitute for the repair of spinal dysraphism in newborns...

INTRODUCTION: Intradural transection of the filum terminale (FTI) is often used to treat tethered cord syndrome. Recently, some have proposed that the extradural part of the filum terminale (FTE) can be sectioned with equal results but with fewer complications. Therefore, the present cadaveric study aimed to evaluate the anatomical foundation of such procedures. METHODS: A posterior lumbosacral approach was performed on five fresh-frozen cadaveric specimens to expose both the FTI and FTE...

Neurogenic bladder occur as a consequence of several conditions, most commonly posterior urethral valves syndrome, spina bifida, tethered cord, sacral agenesis, and Arnold-Chiari malformation. It is characterized by diminished bladder capacity and/or reduced compliance, associated with high-pressure voiding that can lead to deterioration of renal function if left untreated. When medical management fails, bladder reconstruction with bowel (aumentation ileocystoplasty) becomes the treatment of choice for these patients...

Intradural spinal cord abscesses are rare infections in early childhood and usually result from pre-existing congenital anomalies of the spinal column. The formation of abscess may be the result of hematogenous spread. It is treated by surgical and parenteral antibiotic treatment, but some special cases may require additional treatments. This article presents a 4-year-old male patient who was operated because of spina bifida (meningocele and tethered cord) at the external center, and upon complains of not being able to walk after one month, he was operated with the diagnosis of spinal intradural abscess and referred to us to continue his treatment...

Background: Chiari malformations type 1 (CM-1), a developmental anomaly of the posterior fossa, usually presents in adolescence or early adulthood. There are few studies on the national incidence of CM-1, taking into account outcomes based on concurrent diagnoses. To quantify trends in treatment and associated diagnoses, as retrospective review of the Kid's Inpatient Database (KID) from 2003-2012 was conducted. Methods: Patients aged 0-20 with primary diagnosis of CM-1 in the KID database were identified...

INTRODUCTION: Currarino's syndrome (CS) is an autosomal dominant disorder of embryonic development causing a rare malformating syndrome characterized by a triad of an anorectal malformations, presacral mass (most commonly an anterior sacral meningocele) and sacral bony defects. Mutations of the HLXB9 gene have been identified in most CS cases, but a precise genotype-phenotype correlation has not been described so far. Family screening is obligatory. The diagnosis is usually made during childhood and rarely in adulthood...

OBJECTIVES: Cerebrospinal fluid leaks are a frequent complication of spinal surgery, with reported rates between 2 and 20%. Management is highly variable and dependent on comorbidities, complexity of the index procedure, and surgeons' experience. Treatment options include primary or delayed repair, with or without spinal drainage. Using a retrospective cohort, the authors aim to identify the appropriate management of iatrogenic spinal cerebrospinal fluid (CSF) leaks. PATIENTS AND METHODS: We queried our institutional database for postoperative spinal CSF leaks between 1/1/2007 and 3/14/2017 using Current Procedural Terminology (CPT) and International Classification of Disease (ICD) codes...

BACKGROUND AND AIM: The sacral ratio (SR) is a well-established tool to quantify sacral development in patients with anorectal malformations (ARM) and can be used as a predictor of fecal continence. We hypothesized that a lower SR correlated with the presence of urologic and renal malformations. METHODS: We retrospectively reviewed the medical records of patients with ARM treated at our center from 2014 to 2016. We measured the lateral SR as a marker for sacral development and assessed the spine for the presence of tethered cord (TC)...

BACKGROUND: A lumbar lipomyelocele is a closed spinal dysraphism that can cause tethered cord syndrome. Between 5% and 15% of spinal dysraphism surgery cases are burdened with complications, the most common being wound infections or dehiscence and cerebrospinal fluid leak. Acute communicating hydrocephalus has never been described as a complication of this type of surgery. CASE DESCRIPTION: A 6-year-old girl who had undergone several surgeries in another institution for lumbar lipomyeloschisis came to our attention for a second opinion about the management of her spinal dysraphism...

RATIONALE: Neurenteric cysts, are rare benign tumors of the central nervous system that are mostly located in the spinal cord and predominantly seen in male children although adult form of the disorder also occurs. The etiology and treatment of this disorder is still a matter of debate. Our case further throws more light on the pathogenesis and treatment of this disorder. PATIENT CONCERNS: A 4-year-old boy presented with 5-month history of cervical lordosis and bilateral lower extremity pain that progressed to his abdomen and upper body...

BACKGROUND: The existence of tethering tracts in spinal dysraphism, other than congenital dermal sinus (CDS), has been recognized and has been summated into an integrated concept of limited dorsal myeloschisis (LDM). OBJECTIVE: To elucidate the underlying embryology of LDM in relation to CDS by focusing on the pathological features of special cases of tethering tracts. METHODS: Out of 389 spinal dysraphism patients who were operated on from 2010 to 2016, 5 patients who had tethering tracts composed of both CDS and LDM (or "probable LDM" if only fibrous tissue was found) were identified...

BACKGROUND: Cerebrospinal fluid (CSF) leaks are a dreaded complication after surgery for tethered cord and are associated with significant patient morbidity. Although many strategies for managing postoperative CSF leaks exist, this problem is still daunting, especially in very young patients. In this study, we compared different management techniques for CSF leaks or significant pseudomeningocele in patients with tethered cord syndrome (TCS). METHODS: We analyzed a cohort of children who underwent surgery for TCS from January 2011 to March 2016 (n = 260) and postoperatively experienced either a CSF leak or significant pseudomeningocele...
