Neurological endovascular therapy is a discipline that has shown effectiveness and safety in the management of intracranial aneurysms, however recanalization persists as one of the most important obstacles to overcome. Precise knowledge of the anatomy and hemodynamics of the aneurysm and the parent artery as well as currently available endovascular devices, are decisive in the analysis and to design a specific treatment plan for each case. In this manner we ensure, as long as possible, success and durability of the treatment.

Spatial accuracy of dose delivery significantly impacts the planning target volume margin in linear accelerator-based intracranial stereotactic radiosurgery.

The impact of three-dimensional (3D) dose delivery accuracy of C-arm linacs on the planning target volume (PTV) margin was evaluated for non-coplanar intracranial stereotactic radiosurgery (SRS). A multi-institutional 3D starshot test using beams from seven directions was conducted at 22 clinics using Varian and Elekta linacs with X-ray CT-based polymer gel dosimeters. Variability in dose delivery accuracy was observed, with the distance between the imaging isocenter and each beam exceeding 1 mm at one institution for Varian and nine institutions for Elekta.

Background: Computed tomography angiography of the head (CTAH) is not routinely obtained during the initial evaluation of patients with traumatic intracranial hemorrhage (ICH); however, it is useful for diagnosing vascular pathologies that may have led to the bleed. The aims of this study were to identify traumatic ICH patient characteristics on presentation that are associated with positive CTAH findings to elucidate which ones should prompt a CTAH and compare outcomes of patients with positive and negative CTAH findings.
Methods: This is a retrospective cohort study of 522 patients who had blunt traumatic ICH and subsequently received CTAH between January 1, 2017, and January 1, 2022.
Unicoronal synostosis is a rare condition leading to anterior plagiocephaly with facial scoliosis and deformation of the anterior cranial fossa. Fronto-orbital advancement and remodelling (FOAR) is the standard of care for management, aiming to normalise the brow shape and position while ameliorating the risk of raised intracranial pressure (ICP) throughout childhood. Published long-term surgical outcome data for unicoronal synostosis is lacking.

Penetrating head trauma is the most fatal form of head injury. Although many cases of penetrating head trauma have been reported in the literature, its management remains complex, requiring a multidisciplinary team, which makes it a challenge in district hospitals where human resources and technical equipment are limited. We aim to present a successful initial management of a case of penetrating head trauma in a rural district hospital before a transfer to a first category hospital.

Background And Objectives: Although previous trials have established the efficacy and safety of endovascular thrombectomy (EVT) in large ischemic core strokes, most of them excluded patients with extracranial internal carotid artery (e-ICA) occlusion. We aimed to compare outcomes in patients with e-ICA occlusion and large ischemic core infarcts treated with EVT vs medical management (MM).
Methods: This was a secondary analysis of the SELECT2 trial, a randomized controlled trial conducted at 31 international sites.
