In this narrative review, different aspects of electroencephalogram (EEG) monitoring during anesthesia are approached, with a special focus on cardiothoracic and vascular anesthesia, from the basic principles to more sophisticated diagnosis and monitoring utilities. The available processed EEG-derived indexes of the depth of the hypnotic component of anesthesia have well-defined limitations and usefulness. They prevent intraoperative awareness with recall in specific patient populations and under a specific anesthetic regimen. They prevent intraoperative overdose, and they shorten recovery times. They also help to avoid lengthy intraoperative periods of suppression activity, which are known to be deleterious in terms of outcome. Other than those available indexes, the huge amount of information contained in the EEG currently is being used only partially. Several other areas of interest regarding EEG during anesthesia have emerged in terms of anesthesia mechanisms elucidation, nociception monitoring, and diagnosis or prevention of brain insults.

Background: Delta large-channel endoscopy and unilateral biportal endoscopy (UBE) are prominent minimally invasive techniques for treating lumbar spinal stenosis, known for minimal tissue damage, clear visualization, and quick recovery. However, rigorous controlled research comparing these procedures is scarce, necessitating further investigation into their respective complications and long-term effectiveness. This randomized controlled trial aims to compare their perioperative outcomes, focusing on postoperative recovery and complications over time.

Purpose: Over time, transit time flow measurement (TTFM) has proven itself as a simple and effective tool for intra-operative evaluation of coronary artery bypass grafts (CABGs). However, metrics used to screen for possible technical error show considerable spread, preventing the definition of sharp cut-off values to distinguish between patent, questionable, and failed grafts. The simulation study presented in this paper aims to quantify this uncertainty for commonly used patency metrics, and to identify the most important physiological parameters influencing it.

Background: Subdural hematoma (SDH) typically occurs due to traumatic brain injury but can arise as a rare complication of procedures like endoscopic third ventriculostomy (ETV).
Case Presentation: We report an unusual case in a 9-year-old male with previous resection of a fourth-ventricle ependymoma at 2 years of age. Seven years post-surgery, he presented with worsening hydrocephalus and underwent ETV.

Patellar tendon rupture (PTR) is a rare and severe postoperative complication of total knee arthroplasty (TKA). Even rarer is the intraoperative occurrence of PTR during TKA. PTR is a major complication as it can lead to chronic disability, functional limitations, and postoperative morbidity.

Purpose: To present updated outcomes after previously describing a novel technique for the robotic repair of parastomal hernias.
Methods: Patients who underwent parastomal hernia repair with a robotic Sugarbaker technique at a tertiary hernia center were identified from an institutional database. The approach involves mesh placement in the intraperitoneal or preperitoneal position after closure of the fascial defect.
