Ganglioneuroblastoma is a variant of neuroblastoma that is surrounded by ganglion cells. It can be difficult to diagnose. [1] Nodular ganglioneuroblastoma can be ...
Awake craniotomy is a neurosurgical technique and type of craniotomy that allows a surgeon to remove a brain tumor while the patient is awake to avoid brain damage.During the surgery, the neurosurgeon performs cortical mapping to identify vital areas, called the "eloquent brain", that should not be disturbed while removing the tumor.
Poorly defined margins may be more suggestive of astrocytoma, while a central location in the spinal cord, hemorrhage, and hemosiderin staining are often seen with ependymoma. Hemangioblastoma and paraganglioma are less usual intramedullary tumors, but since they are more frequently encountered than ganglioglioma, they should also be included ...
A surgeon working in Scotland has developed a way to remove brain tumours the size of apples through patients’ eyebrows in what is believed to be a world-first for the procedure.
Cerebral amyloid angiopathy may cause intraparenchymal hemorrhage even in patients without elevated blood pressure. Unlike hypertension, cerebral amyloid angiopathy does not typically affect blood vessels to deep brain structures. Instead, it is most commonly associated with hemorrhage of small vessels in the cerebral cortex. [2]
Interventional neuroradiology (INR) also known as neurointerventional surgery (NIS), endovascular therapy (EVT), endovascular neurosurgery, and interventional neurology is a medical subspecialty of neurosurgery, neuroradiology, intervention radiology and neurology specializing in minimally invasive image-based technologies and procedures used in diagnosis and treatment of diseases of the head ...
In previous comments soon after the surgery, Kalil had said it was “important to note that (Lula) did not sustain any brain injury. The hematoma, the bleeding, was not inside the brain; it was ...
At a brain temperature of 14 °C, blood circulation can be safely stopped for 30 to 40 minutes. [3] There is an increased incidence of brain injury at times longer than 40 minutes, but sometimes circulatory arrest for up to 60 minutes is used if life-saving surgery requires it. [4] [5] Infants tolerate longer periods of DHCA than adults. [6]
