brain abscess anesthesia

Pulmonary arteriovenous malformations (PAVMs) can be asymptomatic or result in a range of complications such as brain abscesses or cryptogenic emboli, which can contribute to morbidity and mortality if not diagnosed and treated in a timely manner. To date, there have been several reports of delayed diagnosis of PAVMs, which have been largely attributed to the misconception that PAVMs are too rare to be of clinical significance. Furthermore, because intracardiac shunting secondary to a patent foramen ovale (PFO) or atrial septal defect (ASD) also results in a positive saline contrast study with echocardiography, PAVM can be easily misdiagnosed as an intracardiac right-toleft shunt...

BACKGROUND: The present study presents our experience with computed tomography (CT)-guided stereotactic surgery in managing deep-seated brain lesions and provides a background in the expanding fields of morphological stereotactic neurosurgery. METHODS: We conducted this retrospective cohort study on 80 patients managed at the Department of Neurosurgery, Zagazig University Hospitals, Zagazig, Egypt, between January 2019 to January 2021. We targeted patients with morphological stereotactic surgeries performed as the primary management modality of their treatment...

Prolonged neurological symptoms such as "brain fog" and cognitive impairment have occurred after coronavirus disease 2019 (COVID-19) infection. In this report, we describe impaired consciousness caused by cefepime hydrochloride (CFPM) in a patient with cognitive sequalae of COVID-19. A 56-year-old male patient was diagnosed with penile abscess after COVID-19 infection, and a blood culture detected two drug-resistant Pseudomonas aeruginosa strains. Therefore, CFPM 2 g × twice/day was administered on day 71 after intensive care unit admission...

Objective: It is well known that accurate location of the leak in the operation is crucial for repairing cerebrospinal fluid leakage. The study aims to investigate the application of intraoperative injection of normal saline through lumbar drainage in repairing complex leaks. Methods: The fistulas of all patients with CSF leak were located by computed tomography cisternography (CTC) or heavy T2 magnetic resonance imaging (MRI) before surgery. Before anesthesia, the patient underwent lumbar drainage implantation, and then 20 ml of normal saline was slowly injected through the lumbar drainage to observe the patient's response...

Adults patients with congenital heart disease increasingly present for non cardiac surgery. The anesthetic management this type of patients in neurosurgery requires a meticulous surgical anesthetic planning. The need for urgent intervention, with the presence of a congenital heart disease evolved to Eisenmenger Syndrome, associated to a difficult airway, is a challenge for the anesthesiologist. The use of dexmedetomidine may be a valid alternative. We present the case of a patient with Down syndrome, and Eisenmenger syndrome who underwent drainage of brain abscess from the emergency department and was subsequently scheduled for reintervention...

We present an unusual case of a 60-year-old female who developed subtle, new-onset left upper and lower extremity weakness on day five of perioperative thoracic epidural placement. The onset of a focal neurological deficit after epidural placement usually raises suspicion for the presence of an epidural hematoma, abscess, or traumatic cord lesion. However, in this patient, brain imaging revealed a large, previously undiagnosed intracranial mass. Classically, the risk of mass-related intracranial pressure shifts leading to neurological changes is associated with spinal techniques, including diagnostic lumbar puncture, combined spinal-epidural catheter analgesia, and unintended dural puncture during epidural placement...

A 14-year-old American Paint Horse mare was referred for further evaluation of a firm mass with an associated draining tract at the base of the left ear suspected to be a dentigerous cyst. Approximately three months prior, the draining tract had been excised under the presumed diagnosis of an abscess with no improvement. Physical examination revealed a firm mass palpable at the base of the left ear with a draining tract that did not elicit any pain response on palpation. Digital radiographs revealed a 6x11cm mineral mass in the left temporal region...

Paediatric orbital cellulitis is a potential sight- and life-threatening condition. It is a serious infection in children that can result in significant complications, including blindness, cavernous sinus thrombosis, cerebral venous sinus thrombosis, meningitis, subdural empyema, and brain abscess. Of the patients with orbital cellulitis, 17% died from meningitis, and 20% of the survivors had permanent loss of vision. Therefore, the potential for sight- and life-threatening complications makes prompt diagnosis and early treatment very important...

Tetrology of Fallot's (TOF) is the most common cause of cyanotic congenital heart disease, and accounts for 10% of all congenital heart diseases. Right to left shunting and hyperviscosity of blood predisposes these patients to brain abscess. Perioperative management of these patients with uncorrected TOF for noncardiac surgery is a challenge for the anesthesiologists owing to the long-term effects of hypoxia and decreased pulmonary blood flow, resulting in considerable modification of the physiology and neurological complications...

Background  Brain abscess is a rare neurological complication in patients with congenital cyanotic heart disease (CCHD). Perioperative complications are high in patients with CCHD. We evaluated incidence of and risk factors for perioperative complications and their impact on clinical outcomes in patients with CCHD undergoing brain abscess surgery with monitored anesthesia care (MAC) or general anesthesia (GA). Methods  In this single-center retrospective cohort study, data were collected from consecutive patients with CCHD who presented with brain abscess and underwent surgery from January 2006 to December 2018...

BACKGROUND: Odontogenic infection is one of the common infectious diseases in oral and maxillofacial head and neck regions. Clinically, if early odontogenic infections such as acute periapical periodontitis, alveolar abscess, and pericoronitis of wisdom teeth are not treated timely, effectively and correctly, the infected tissue may spread up to the skull and brain, down to the thoracic cavity, abdominal cavity and other areas through the natural potential fascial space in the oral and maxillofacial head and neck...

BACKGROUND: Brain abscess is a life-threatening condition that occurs due to complications during a neurosurgical procedure, direct cranial trauma, or the presence of local or distal infection. Infection in the oral cavity can also be considered a source of brain abscess. CASE PRESENTATION: A 45-year-old male patient was transported with brain abscess in the subcortical white matter. Navigation-guided abscess aspiration and drainage was performed in the right mid-frontal lobe, but the symptoms continued to worsen after the procedure...

The number of patients with pneumonia has been increasing as the population ages, and most fatal pneumonia cases are the elderly with aspiration pneumonia. Although aspiration pneumonia leads to poor short- and long-term prognosis, there have been no practical ways to diagnose it precisely. Persistent subclinical aspiration without any subjective symptoms is problematic in clinical practice in patients with aspiration pneumonia, and physicians can only use aspiration risks such as brain infarction to diagnose aspiration pneumonia...

Anterior cranial base reconstruction is occasionally necessary following severe trauma. Several methods for reconstruction have been described and some authors have described their experiences regarding the use of a pericranial flap for anterior skull base reconstruction after trauma. A 26-year-old woman was admitted to our department with multiple facial bone fractures identified using facial bone computed tomography. Plastic surgeons performed surgery under general anesthesia for the patient's nasal bone fractures...

INTRODUCTION: Trauma is a major contributor to global morbidity and mortality, and injury to the central nervous system is the most common cause of death in these patients. While the provision of surgical services is being recognized as essential to global public health efforts, specialty areas such as neurosurgery remain overlooked. METHOD: This is a retrospective case review of patients with operable lesions, such as extra-axial hematomas and unstable depressed skull fractures that underwent neurosurgical interventions under local anesthesia...

OBJECTIVES: Fluorescein Sodium (FL) enhances areas in the brain with a disrupted blood brain barrier (BBB). Solitary brain abscesses (BA) are characterized by the pathognomonic finding of BBB disruption. Consequently, FL may have the potential to improve the intra-operative visualization of BA. Here, we report a series of patients with BA that where treated surgically after application of FL in combination with a dedicated light filter integrated in the surgical microscope. METHODS: 7 patients (4 female, 3 male; mean age 53...

AIM: A retrospective analysis of 126 consecutive computed tomography (CT)-guided, frame-based stereotactic procedures in 121 patients is presented to evaluate the diagnostic yield, accuracy, complications, management of non-diagnostic cases and followup. MATERIAL AND METHODS: The medical records of the identified patients were investigated retrospectively. Age, sex, surgical procedures, histopathological diagnosis, diagnostic yield, accuracy, complications, management of non-diagnostic cases and follow-up were analyzed in 121 consecutive patients...

CASE DESCRIPTION A 22-year-old male gorilla (Gorilla gorilla gorilla) housed in a zoo was evaluated for signs of lethargy, head-holding, and cervical stiffness followed by development of neurologic abnormalities including signs of depression, lip droop, and tremors. CLINICAL FINDINGS Physical examination under general anesthesia revealed a tooth root abscess and suboptimal body condition. A CBC and serum biochemical analysis revealed mild anemia, neutrophilia and eosinopenia consistent with a stress leukogram, and signs consistent with dehydration...

Children with uncorrected cyanotic congenital heart diseases can present for non cardiac surgeries. They pose several challenges to the Anaesthesiologist, especially when they are posted for emergency surgery, due to the complex haemodynamic changes secondary to the heart disease. Pentalogy of Fallot (POF) is a rare form of congenital heart disease characterized by the association of Tetralogy of Fallot (TOF) with an atrial septal defect (ASD). TOF is the leading cause of intracardiac right to left shunt and is the commonest type of cyanotic congenital heart disease to cause a brain abscess...
