Cranioplasty Outcomes from a Tertiary Hospital in a Developing Country.

BACKGROUND: Decompressive craniectomy (DC) is a surgical procedure to treat refractory increase in intracranial pressure. DC is frequently succeeded by cranioplasty (CP), a reconstructive procedure to protect the underlying brain and maintain cerebrospinal fluid flow dynamics. However, complications such as seizures, fluid collections, infections, and hydrocephalus can arise from CP. Our aim is to investigate these complications and their possible risk factors and to discuss whether early or late CP has any effect on the outcome. MATERIALS AND METHODS: A single-center retrospective cohort study was performed, including patients who underwent CP after DC between January 2014 and January 2022. Relevant information was collected such as demographics, type of brain injury, materials used in CP, timing between DC and CP, and postoperative complications. Ultimately, 63 patients were included in our study. We also compared the complication rate between patients who underwent late CP after DC (>90 days) against patients who underwent early CP (<90 days). RESULTS: Most patients were male (78%). The sample median age was 29 years, with pediatric patients, accounting for 36% of the samples. Overall complication rate was 57% and they were seizure/epilepsy in 50% of the patients, fluid collection (28%), infections (25%), posttraumatic hydrocephalus (17%), and bone defect/resorption (3%). Twenty-two percent of patients with complications required reoperation and underwent a second CP. The median (interquartile range) duration between the craniotomy and the CP was 56 (27-102) days, with an early (≤3 months) percentage of 68%. We found no significant difference between early (≤3 months) and late (>3 months) CP regarding complication rates. CONCLUSION: Despite CP being a simple procedure, it has a considerable rate of complications. Therefore, it is important that surgeons possess adequate knowledge about such complications to navigate these challenges more effectively.

Résumé Contexte:La craniectomie décompressive (DC) est une intervention chirurgicale destinée à traiter l'augmentation réfractaire de la pression intracrânienne. La DC est fréquemment remplacée par une cranioplastie (CP), une procédure reconstructive visant à protéger le cerveau sous-jacent et à maintenir la dynamique du flux du liquide céphalo-rachidien. Cependant, des complications telles que des convulsions, des collections de liquides, des infections et une hydrocéphalie peuvent survenir en raison de la CP. Notre objectif est d'étudier ces complications et leurs facteurs de risque possibles et de discuter si une CP précoce ou tardive a un effet sur le résultat.Matériels et méthodes:Une étude de cohorte rétrospective monocentrique a été réalisée, incluant des patients ayant subi une PC après une DC entre janvier 2014 et janvier 2022. Des informations pertinentes ont été collectées telles que les données démographiques, le type de lésion cérébrale, les matériaux utilisés dans la PC, le timing entre la DC et CP et complications postopératoires. Au final, 63 patients ont été inclus dans notre étude. Nous avons également comparé le taux de complications entre les patients ayant subi une CP tardive après une DC (> 90 jours) et ceux ayant subi une CP précoce (<90 jours).Résultats:La plupart des patients étaient des hommes (78 %). L'âge médian de l'échantillon était de 29 ans, les patients pédiatriques représentant 36 % des échantillons. Le taux global de complications était de 57 % et il s'agissait de convulsions/épilepsie chez 50 % des patients, d'accumulation de liquide (28 %), d'infections (25 %), d'hydrocéphalie post-traumatique (17 %) et de défauts/résorptions osseuses (3 %). Vingt­deux pour cent des patients présentant des complications ont dû être réopérés et ont subi une deuxième CP. La durée médiane (intervalle interquartile) entre la craniotomie et la CP était de 56 (27 à 102) jours, avec un pourcentage précoce (≤ 3 mois) de 68 %. Nous n'avons trouvé aucune différence significative entre la PC précoce (≤ 3 mois) et tardive (> 3 mois) en ce qui concerne les taux de complications.Conclusion:Bien que la CP soit une procédure simple, elle entraîne un taux de complications considérable. Il est donc important que les chirurgiens possèdent des connaissances adéquates sur ces complications pour relever ces défis plus efficacement.

Cystic dilatation of the ventriculus terminalis: A narrative review.

Introduction: The terminal ventricle, also known as the fifth ventricle, is a tiny relic cavity in the conus medullaris of the human spinal cord. Our purpose in bringing attention to this condition is to get the word out about the signs and symptoms, diagnostic hurdles, and therapeutic options available for it. Methods: All relevant studies involving patients diagnosed with ventriculus terminalis (VT) were retrieved from PubMed, Google Scholar, and Scopus. Studies published in complete English language reports were included. The terms VT, terminal ventricle, and 5th ventricle. Age, gender, presenting symptoms, magnetic resonance imaging findings, treatment, and outcome of patients with ventriculus terminalis were all included and recorded. Results: The average age of the patients was 39 years, and there were 13 men among them (14.4%). Motor deficits and sciatica were the most commonly reported symptoms in 38 and 34 patients (42.2%, 37.7%), respectively. In 48 patients (53.3%), cyst fenestration was performed, and in 25 patients (27.7%), myelotomy was performed. Fifty-eight patients (64.4%) saw a reduction in cyst size after surgery. The majority of patients reported an improvement in their symptoms in 64 cases (51.1%), with only three cases (3.3%) reporting a worsening. Conclusions: In cases where the VT is the source of symptoms such as motor, sensory, or bladder dysfunction, surgical intervention is recommended. This review compiles information from the available literature to shed light on the anatomy, clinical presentation, imaging, and treatment options for this variant. It also aims to pinpoint any potential drawbacks or restrictions connected to the surgical techniques.

AB Blood Group Confers Higher Risk for Primary Brain Tumors in Pediatrics.

PURPOSE: Our current study investigates the relationship between ABO blood groups and brain tumor incidence in the Jordanian pediatric population in a case-controlled manner. PATIENTS AND METHODS: This case-control study targeted pediatric primary brain tumor patients and tumor-free controls. Cases included patients younger than 18 when given a histologically confirmed diagnosis with a primary brain tumor, ascertained from two tertiary hospitals in Jordan. Controls were age- and gender-matched to cases and acquired from JUH pediatric clinics, with an exclusion for all patients with a personal history of tumors. Through using available records and calling guardians, our team obtained patients' and controls' blood groups. RESULTS: Our case control included 81 (35.4%) pediatric primary brain tumor patients and age- and gender-matched tumor-free controls 148 (64.6%). When compared to O blood group, patients with A and B blood groups were not at higher risk of developing pediatric primary brain tumors (P=0.742, P=1.000, respectively). However, Chi-square analysis revealed a 2.79-fold higher risk for pediatric primary brain tumors in AB blood group patients (P=0.024). Gender-specific analysis revealed a 3.42-fold higher risk for pediatric brain tumors in AB blood group males when compared to O blood group males. CONCLUSION: This work represents the first published study on the association between blood groups and pediatric brain tumors. With future research with larger samples and control of confounding factors, AB blood group may become a more established risk factor for pediatric brain tumors, aiding in screening.

Glioblastoma multiforme of the cerebellum.

Glioblastoma multiforme (GBM) is a highly malignant glial tumor seen commonly in the cerebral hemispheres, but rarely encountered in the cerebellum. It may occur at any age, but is seen more often in adult age groups. Despite its rarity, GBM should be considered in patients with a ring-enhancing lesion in the cerebellum. No consensus regarding the best management has yet been established. However, multimodal treatment is currently available to deal with these lesions: wide excision with radiochemotherapy may improve and prolong the patients life. Although the outcome remains dismal, we emphasize that timely multi modal treatment may provide the patient a better outcome and longer life. Herein, we report 2 new cases of cerebellar GBM and discuss their outcome and present a review of the relevant literature.
