Development and initial experience of a novel classification system for patients with brain stem haemorrhage.

Introduction: There is no uniform classification standard for brain stem haemorrhage. On the basis of previous experience in the treatment of brainstem haemorrhage, this study explored and established a set of criteria for brainstem haemorrhage classification, risk-stratified such patients and guided the selection of treatment options so as to achieve accurate and standardized diagnosis and treatment.

Material And Methods: Thirty patients with brainstem haemorrhage from April 2019 to May 2022 were included.

Imaging characteristics, misdiagnosis and microsurgical outcomes of patients with spinal dural arteriovenous fistula: a retrospective study of 32 patients.

Background: Spinal dural arteriovenous fistula (SDAVF) is an extremely rare spinal vascular malformation. As SDAVF exhibits no specific clinical manifestations nor diverse imaging results, it is easily misdiagnosed, resulting in delayed treatment and irreversible neurological damage. Most patients were initially misdiagnosed, but there were few reports on reducing misdiagnosis.
