Toward the "Perfect" Shunt: Historical Vignette, Current Efforts, and Future Directions
Adv Tech Stand Neurosurg. 2024;50:1-30. doi: 10.1007/978-3-031-53578-9_1.ABSTRACTAs a concept, drainage of excess fluid volume in the cranium has been around for more than 1000 years. Starting with the original decompression-trepanation of Abulcasis to modern programmable shunt systems, to other nonshunt-based treatments such as endoscopic third ventriculostomy and choroid plexus cauterization, we have come far as a field. However, there are still fundamental limitations that shunts have yet to overcome: namely posture-induced over- and underdrainage, the continual need for valve opening pressure especially in pediatric ca...

Ependymoma from Benign to Highly Aggressive Diseases: A Review
Adv Tech Stand Neurosurg. 2024;50:31-62. doi: 10.1007/978-3-031-53578-9_2.ABSTRACTEpendymomas comprise biologically distinct tumor types with respect to age distribution, (epi)genetics, localization, and prognosis. Multimodal risk-stratification, including histopathological and molecular features, is essential in these biologically defined tumor types. Gross total resection (GTR), achieved with intraoperative monitoring and neuronavigation, and if necessary, second-look surgery, is the most effective treatment. Adjuvant radiation therapy is mandatory in high-risk tumors and in case of residual tumor. There is yet growing e...

Intraventricular Tumors: Surgical Considerations in Lateral and Third Ventricular Tumors
Adv Tech Stand Neurosurg. 2024;50:63-118. doi: 10.1007/978-3-031-53578-9_3.ABSTRACTManagement of lateral and third ventricular tumors has been a challenge for neurosurgeons. Advances in imaging and pathology have helped in a better understanding of the treatment options. Technical refinement of microsurgical technique and addition of endoscopy has enabled more radical excision of tumors, when indicated, and added more safety.A proper understanding of the pathology at various ages and treatment options is continuously evolving. Many pediatric tumors are amenable to conservative surgical methods with effective complementary ...

Pediatric-Like Brain Tumors in Adults
Adv Tech Stand Neurosurg. 2024;50:147-183. doi: 10.1007/978-3-031-53578-9_5.ABSTRACTPediatric brain tumors are different to those found in adults in pathological type, anatomical site, molecular signature, and probable tumor drivers. Although these tumors usually occur in childhood, they also rarely present in adult patients, either as a de novo diagnosis or as a delayed recurrence of a pediatric tumor in the setting of a patient that has transitioned into adult services.Due to the rarity of pediatric-like tumors in adults, the literature on these tumor types in adults is often limited to small case series, and treatment d...

The Value of Intraoperative Ultrasound in Brain Surgery
Adv Tech Stand Neurosurg. 2024;50:185-199. doi: 10.1007/978-3-031-53578-9_6.ABSTRACTFavorable clinical outcomes in adult and pediatric neurosurgical oncology generally depend on the extent of tumor resection (EOR). Maximum safe resection remains the main aim of surgery in most intracranial tumors. Despite the accuracy of intraoperative magnetic resonance imaging (iMRI) in the detection of residual intraoperatively, it is not widely implemented worldwide owing to enormous cost and technical difficulties. Over the past years, intraoperative ultrasound (IOUS) has imposed itself as a valuable and reliable intraoperative tool g...

Clipping of Anterior Circulation Aneurysms: Operative Instructions and Safety Rules for Young Cerebrovascular Surgeons
CONCLUSION: In the setting of an IA clipping, particularly when ruptured, the young cerebrovascular surgeon needs to respect an algorithm of safety rules, which are essential not only to avoid major complications, but they may intervene during the difficulties helping to manage potentially life-tethering conditions.PMID:38592532 | DOI:10.1007/978-3-031-53578-9_7 (Source: Advances and Technical Standards in Neurosurgery)

360 Degrees Endoscopic Access to and Through the Orbit
This study aims to provide a comprehensive description of endoscopic-assisted techniques that enable a 360° access to the orbit and its surrounding regions. The investigation will delve into indications, advantages, and limitations associated with different approaches, while also drawing comparisons between endoscopic approaches and traditional microsurgical transcranial approaches.PMID:38592533 | DOI:10.1007/978-3-031-53578-9_8 (Source: Advances and Technical Standards in Neurosurgery)

Pros and Cons of Minimally Invasive Spine Surgery
Adv Tech Stand Neurosurg. 2024;50:277-293. doi: 10.1007/978-3-031-53578-9_9.ABSTRACTThis paper reviews current knowledge on minimally invasive spine surgery (MISS). Although it has significant advantages, such as less postoperative pain, short hospital stay, quick return to work, better cosmetics, and less infection rate, there are also disadvantages. The long learning curve, the need for special instruments and types of equipment, high costs, lack of tactile sensation and biplanar imaging, some complications that are hard to treat, and more radiation to the surgeon and surgical team are the disadvantages.Most studies rema...

Evaluation and Treatment of Patients with Small Posterior Cranial Fossa and Chiari Malformation, Types 0 and 1
Adv Tech Stand Neurosurg. 2024;50:307-334. doi: 10.1007/978-3-031-53578-9_11.ABSTRACTThe diagnosis of Chiari I malformation is straightforward in patients with typical signs and symptoms of Chiari I malformation and magnetic resonance imaging (MRI) confirming ≥5 mm of cerebellar tonsillar ectopia, with or without a syrinx. However, in many cases, Chiari I malformation is discovered incidentally on MRI to evaluate global headache, cervical radiculopathy, or other conditions. In those cases, the clinician must consider if cerebellar tonsillar ectopia is related to the presenting symptoms. Surgical decompression of the cere...

Neurosurgeons tend to adopt ethics according to their own values and to what they see and learn from teachers. Neurosurgeons, in general, are aware about ethical codes and the patient's rights. However, the philosophy, concept...
