Microsurgical Techniques for Paraclinoid Aneurysms: A Single-Center Series.
World Neurosurg
January 2025
Department of Neurosurgery, Hospital Nacional Dos de Mayo, Lima, Peru.
Introduction: Microsurgery for paraclinoid aneurysms remains the first line of treatment in resource-constrained settings. The authors describe their institutional experience and evaluate functional outcomes after microsurgical treatment of paraclinoid aneurysms.
Methods: A retrospective review of clinical records was conducted.
Retrograde thrombosis of the superficial sylvian vein following liquid adhesive hemostat use during craniotomy: illustrative case.
J Neurosurg Case Lessons
January 2025
Department of Neurosurgery, University of California, Irvine, Orange, California.
Background: Intravascular injection of liquid adhesive hemostats is a rare but serious complication that can result in cerebral thromboembolism.
Observations: A 64-year-old female underwent orbitozygomatic craniotomy for posterior communicating artery aneurysm clipping with the routine use of a flowable hemostatic agent during extradural dissection. After placement of the aneurysm clip, flow was confirmed through the parent vessel and nearby branches.
Traumatic middle meningeal artery pseudoaneurysm: Case report and review of literature.

Department of Neurosurgery, National Institute of Mental Health and Neuroscience (NIMHANS), Bengaluru, India.
Traumatic aneurysms represent less than 1 percent of intracranial aneurysms and middle meningeal artery pseudoaneurysms are even rare. Traumatic aneurysms are usually pseudoaneurysms formed by the rupture of all the layers of the vessel wall. They are associated with high mortality as they can present as epidural, subdural, and rarely intraparenchymal hematoma.

Microcirculation
January 2025
Geoffrey Jefferson Brain Research Centre, Manchester Academic Health Science Centre, Northern Care Alliance NHS Foundation Trust, University of Manchester, Manchester, UK.
Objective: Cerebral blood flow (CBF) decline is increasingly recognized as an area of importance for targeting neurodegenerative disorders, yet full understanding of the mechanisms that underlie CBF changes are lacking. Animal models are crucial for expanding our knowledge as methods for studying global CBF and neurovascular coupling in humans are limited and require expensive specialized scanners.
Methods: Use of appropriate animal models can increase our understanding of cerebrovascular function, so we have combined chronic cranial windows with in vivo two-photon and laser speckle microscopy and ex vivo capillary-parenchymal arteriole (CaPA) preparations.
Microsurgical Resection of a Midbrain Cavernous Malformation via the Paramedian Supracerebellar Infratentorial Translateral Mesencephalic Sulcus Approach Using the Dynamic Lateral Semisitting Position: Two-Dimensional Operative Video with 3-Dimensional Anatomical Models.
World Neurosurg
January 2025
Department of Neurosurgery, Altınbaş University, Istanbul, Turkiye. Electronic address:
Brainstem cavernous malformations are relatively rare lesions with a higher tendency of hemorrhage than supratentorial cavernous malformations. Due to the compact arrangement of fiber tracts and nuclei of the region, any hemorrhagic event can cause severe neurological deficits. This eloquent architecture of the area also makes any surgical attempt challenging.
