The Extension of Traumatic Subdural Hematoma into the Interhemispheric Fissure Is Associated with Coagulation Disorders: A Retrospective Study.

Background:  This study investigates the correlation of the radiologic sign of interhemispheric subdural hematoma (iSDH) in different injury patterns with clinical coagulation disorders. It is hypothesized that the presence of iSDHs is correlated with clinical coagulation disorders in patients with traumatic brain injuries and subdural hematoma (SDH).

Methods:  Between January 1, 2020 and June 30, 2022, 154 patients with SDH were identified.

Impact of early follow-up CT in the conservative management of traumatic brain injury on surgical decision making: A retrospective, single-center analysis with special respect to coagulopathy.

Introduction: Initial management of traumatic brain injury (TBI) without immediate need for surgical therapy varies across centers. The additional value of routine repeat cranial computerized tomography (CT) to neurological monitoring is controversial. This retrospective study investigates the impact of routine follow-up CT after 6 h (CT6h) in initially conservatively managed TBI on surgical decision making.

Operative V2 decompression for traumatic vertebrobasilar insufficiency: illustrative case.

Background: Blunt vertebral artery injuries after cervical trauma due to the close anatomical relationship of the vertebral artery to the cervical spine may have fatal consequences because of posterior circulation ischemia and vertebrobasilar insufficiency. While the standard of care remains medical treatment by anticoagulation or antiplatelet therapy, surgical decompression of the vertebral artery is rarely indicated.

Observations: The authors present a case of selective decompression of a traumatically constricted vertebral artery within the transverse foramen of C2 presenting with vertebrobasilar insufficiency due to bilateral aplasia of the posterior communicating arteries and contralateral hypoplasia of the vertebral artery.

A Step-by-Step Dissection of Cerebral Pathologies for Neurosurgical Trainees: The Middle Cerebral Artery Bifurcation Aneurysm.

Background:  Aneurysmal subarachnoid hemorrhage remains one of the most prevalent causes of strokes in the young causing a high socioeconomic damage. Both emergent and elective treatments of intracranial aneurysms remain essential challenges for neurovascular centers. We aim to present conceptual education on clip ligation of middle cerebral artery bifurcation aneurysms in an accessible and structured way to maximize the educational takeaway of residents from aneurysm cases.

Percheron-like artery infarction after transsphenoidal surgery: illustrative case.

Background: The transsphenoidal approach to the skull base has enjoyed increasing popularity for surgery of the sellar region avoiding brain retraction and causing few severe complications. While vitally important vessels in this region show a high degree of variability, some anatomical variants might be involved in characteristic complications.

Observations: We present the case of a 40-year-old female patient with acromegaly due to a pituitary adenoma that was transsphenoidally operated.
