Hemispheric epilepsy is quite frequent in children, compared with adults, and encompasses pathological substrates as diverse as hemimegalencephaly, Rasmussen encephalitis, Sturge-Weber syndrome, and porencephaly, among others. These patients most often become pharmacoresistant and thus require surgical management. Although anatomical hemispherectomy is a possibility, the technique that is favored by most epilepsy surgery centers worldwide is functional hemispherotomy, which results in equivalent outcomes with fewer postoperative complications. Therefore, it is essential that pediatric epilepsy neurosurgeons become familiar with these techniques. The present video describes in detail all surgical aspects of the perisylvian hemispherotomy.

Deep brain stimulation (DBS) has emerged as an important therapeutic option for several movement disorders; however, the management of acute complications, such as acute subdural hematoma (ASDH), remains challenging. This is the case of a 71-year-old woman with Parkinson\'s disease who developed ASDH 12 years after bilateral DBS placement. On admission with altered consciousness, imaging revealed significant displacement of the DBS electrodes because of the hematoma. Emergent craniotomy with endoscopic evacuation was performed with preservation of the DBS system. Postoperatively, complete evacuation of the hematoma was confirmed, and the patient experienced significant clinical improvement. ASDH causes significant electrode displacement in patients undergoing DBS. After hematoma evacuation, the electrodes were observed to return to their proper position, and the patient exhibited a favorable clinical response to stimulation. To preserve the DBS electrodes, endoscopic hematoma evacuation via a small craniotomy may be useful.

The differences in complication rates between the direct anterior and posterior approaches for hemiarthroplasty in elderly patients with femoral neck fractures are not yet fully understood. Dislocation, a severe complication associated with increased mortality and often requiring additional surgery, may occur less frequently with the direct anterior approach compared to the posterior approach. Careful consideration of patient demographics is essential when planning the surgical approach. Future research in this area should focus on robust randomized controlled trials involving elderly patients recovering from femoral neck fractures.

Dual mobility (DM) bearings have gained significant attention in the field of total hip arthroplasty (THA) as a valid treatment option in cases of revision for instability after THA whereas its use in primary THA is still a matter of debate. This manuscript explores the pathology, incidence, diagnosis, treatment options, prognosis, ongoing studies in the literature, and future perspectives related to the use of DM bearings employed in primary THA. DM bearings are primarily designed to address one of the major concerns in THA: Instability of the prosthetic hip. Instability is both for the surgeon and the patient a devastating postoperative complication, leading to significant pain and subsequent apprehension by the patient and may require revision surgeries. The use of DM implants poses the worry of wear-related complications, such as accelerated polyethylene wear and osteolysis, which also pose challenges to long-term implant survival. This technique has seen a steady rise in recent years, with multiple studies reporting favorable outcomes. The incidence of their utilization varies among institutions and surgeons, reflecting differing preferences and patient populations. The diagnosis of instability and wear-related complications in THA often involves clinical assessment, imaging modalities such as X-rays, computed tomography scans, and sometimes advanced imaging techniques like magnetic resonance imaging. DM bearings can be considered as an option when patients present neurologic pathologies such as Parkinson\'s disease or recurrent dislocations after THA. DM bearings provide an additional articulation point within the implant, facilitating a greater range of motion and inherent stability. This design allows for reduced risk of dislocation and improved functional outcomes. Various implant manufacturers offer different designs and sizes of DM bearings to suit individual patient needs. Current literature suggests that the use of DM bearings in primary THA has demonstrated promising outcomes in terms of enhanced stability, reduced dislocation rates, and improved patient satisfaction. However, long-term studies with larger patient cohorts are necessary to establish the durability and longevity of these implants. Several ongoing studies are investigating the role of DM bearings in primary THA. These studies focus on evaluating long-term implant survivorship, assessing wear patterns, analyzing patient-reported outcomes, and comparing the effectiveness of DM bearings with traditional THA designs. The future of DM bearings in primary THA holds potential for further advancements. Research efforts are aimed at refining implant materials, optimizing designs, and studying the influence of surgical techniques on implant performance. Additionally, continued investigation into the long-term outcomes and cost-effectiveness of DM bearings will play a crucial role in shaping their future use. While further research is warranted, the current evidence supports their potential as a beneficial solution in improving surgical outcomes and patient satisfaction.

BACKGROUND: Intracerebral hemorrhage (ICH) is a severe manifestation of stroke, demonstrating notably elevated global mortality and morbidity. Thus far, effective therapeutic strategies for ICH have proven elusive. Currently, minimally invasive techniques are widely employed for ICH management, particularly using endoscopic hematoma evacuation in cases of deep ICH. Exploration of strategies to achieve meticulous surgery and diminish iatrogenic harm, especially to the corticospinal tract, with the objective of enhancing the neurological prognosis of patients, needs further efforts.
METHODS: We comprehensively collected detailed demographic, clinical, radiographic, surgical, and postoperative treatment and recovery data for patients who underwent endoscopic hematoma removal. This thorough inclusion of data intends to offer a comprehensive overview of our technical experience in this study.
RESULTS: One hundred fifty-four eligible patients with deep supratentorial intracerebral hemorrhage who underwent endoscopic hematoma removal were included in this study. The mean hematoma volume was 42 ml, with 74 instances of left-sided hematoma and 80 cases of right-sided hematoma. The median Glasgow Coma Scale (GCS) score at admission was 10 (range from 4 to 15), and the median time from symptom onset to surgery was 18 (range 2 to 96) h. The mean hematoma clearance rate was 89%. The rebleeding and mortality rates within 1 month after surgery were 3.2% and 7.8%, respectively. At the 6-month mark, the proportion of patients with modified Rankin Scale (mRS) scores of 0-3 was 58.4%.
CONCLUSIONS: Both the reduction of surgery-related injury and the protection of the residual corticospinal tract through endoscopic hematoma removal may potentially enhance neurological functional outcomes in patients with deep ICH, warranting validation in a forthcoming multicenter clinical study.

UNASSIGNED: CEA using regional anesthesia is described in detail.
UNASSIGNED: Successful use of regional anesthesia during CEA without complication.
UNASSIGNED: Regional anesthesia for CEA is an advantageous approach for cervical plaque removal in appropriate patients. Thoughtful patient selection, as well as understanding of anatomy and its variants, is required. Potential advantages and disadvantages are discussed.

OBJECTIVE: Acute rupture and hemorrhage of pediatric brain arteriovenous malformations (AVMs) may lead to cerebral herniation or intractable intracranial hypertension, necessitating emerging surgical interventions to alleviate intracranial pressure. However, there is still controversy regarding the timing of treatment for ruptured AVMs. This study aimed to assess the feasibility of utilizing three-pillar expansive craniotomy (3PEC) at different times during the treatment of pediatric ruptured supratentorial AVMs.
METHODS: A retrospective analysis was conducted on all consecutive cases of acute rupture in supratentorial AVMs children who underwent 3PEC at a single institution from 2020 to 2022. General information, clinical characteristics, radiological data, and prognosis were reviewed and analyzed.
RESULTS: Thirteen children were included in the analysis. The intracranial pressure of all patients decreased to below 15 mmHg within 10 days. The expansion volume of the cranial cavity of the patients increased by 18.3 cm3 (95% CI, 10.2- 26.3; P < .001) compared to the hematoma volume. None of the patients required decompressive craniectomy due to intractable intracranial hypertension caused by cerebral swelling. The median waiting period for patients with delayed AVMs treatment was 8 days, during which no rebleeding occurred.
CONCLUSIONS: Emergency intervention with 3PEC in children experiencing acutely ruptured supratentorial AVMs appears to be feasible. For children requiring delayed management of the AVMs, 3PEC may diminish the risk of rebleeding during the waiting period and shorten the waiting period.

OBJECTIVE: To assess the feasibility, effectiveness and safety of the robotic surgical approach in the treatment of severe diaphragmatic endometriosis (DE).
METHODS: Retrospective single-center study using data prospectively recorded in the Franco-European Multidisciplinary Institute of Endometriosis (IFEMendo) database and National observatory for endometriosis (NoEndo) database.
METHODS: Tertiary referral center. Endometriosis care center.
METHODS: Sixty consecutive patients undergoing robotic excision of severe DE from January 2020 to July 2023.
METHODS: Robotic excision of severe DE.
METHODS: Categorical and continuous variables were evaluated and compared using descriptive statistics. A p-value of <0.05 was considered statistically significant.
RESULTS: Full thickness diaphragmatic resection was performed in 76.7% of patients (46/60), partial diaphragmatic muscle resection in 10% (6/60) of cases. Peritoneal stripping technique was performed in 60% (36/60) of patients, divided as follows: as the only technique in case of extensive superficial diaphragmatic involvement in 13.3% of cases (8/60); in addition to full-thickness or partial diaphragmatic resection in case of concomitant multiple foci in 46.7% of patients (28/60). Median operative time was 79.6 minutes with no statistically significative difference related to the surgeon performing surgery (p>0.05). Intraoperative and postoperative complications occurred in 1.7% (1/60) and 6.6% (4/60) of cases, respectively. Diaphragmatic hernia (Clavien-Dindo 3b) was the most common postoperative complication and required surgical repair in all cases. Median hospital stay was 24 hours. The rate of patients with complete recovery from DE symptoms has gradually increased during follow-up, reaching 89% after 12 months from surgery.
CONCLUSIONS: In this case series, robotic treatment of severe diaphragmatic endometriosis in expert hands was feasible, effective and safe.
UNASSIGNED: A robotic stepwise approach allows safe and radical excision of a severe form of diaphragmatic endometriosis.
