C2 Vertebra: An Enigma for Young Spine/Neurosurgeons.
J Neurol Surg B Skull Base
February 2025
Department of Neurosurgery, All India Institute of Medical Sciences, Jodhpur, Rajasthan, India.
Instrumentation of C2 vertebra is considered the most difficult for young neurosurgeons and trainees due to its complex anatomical structures, variety of surgical approaches and techniques, and proximity to important neurovascular structures. Key points from a surgical perspective for midline posterior approach is described in the era of neuroradiological advancements. Computed tomography angiographies (CTAs) of a total of 92 patients were evaluated with special attention to the key findings for insertion of screws for craniovertebral junction (CVJ) fixations.

Oper Neurosurg (Hagerstown)
January 2025
Department of Neurosurgery, NYU Langone Health, New York, New York, USA.
Background And Objectives: Three-column osteotomy (3CO) offers substantial spinal deformity correction. Thoracic neurovascular bundle sacrifice is often required, and anterior spinal artery (ASA) perfusion can be compromised. Spinal angiography allows localization of variable ASA vascular contribution.

J Neurosurg Case Lessons
January 2025
Department of Neurosurgery, Faculty of Medicine, Azad Tehran University of Medical Sciences, Tehran, Iran.
Background: Pedicle screw insertion in posterior spinal surgery can cause vascular injuries, including rare intercostal artery pseudoaneurysms, which are typically discovered incidentally during reimaging. Onyx embolization is an effective treatment for small artery pseudoaneurysms.
Observations: A 36-year-old man who had initially presented with back pain that remained unresponsive to nonsteroidal anti-inflammatory drugs was diagnosed with a T7-8 sarcomatous lesion confirmed by magnetic resonance imaging and biopsy.
Detecting asymptomatic cement pulmonary embolisms following vertebral augmentation using dual-energy computed tomography pulmonary angiography.
J Formos Med Assoc
January 2025
Department of Medical Imaging, National Taiwan University Hospital, Taipei, Taiwan; Department of Medical Imaging, National Taiwan University Cancer Center, Taipei, Taiwan.
Background And Purpose: Dual-energy computed tomography (DECT) pulmonary angiography can reliably detect cement pulmonary embolisms (CPEs) and parenchymal perfusion defects. This prospective observational study investigated CPEs in asymptomatic patients using DECT.
Methods: We enrolled 42 patients who underwent vertebroplasty or received cement screws for vertebral augmentation, examining them using spinal computed tomography and DECT pulmonary angiography.
Successful Management of Thyrocervical Trunk Aneurysm Ruptured into the Thoracic Cavity After Cesarean Section in Nonstable Patient with Neurofibromatosis Type I.
Medicina (Kaunas)
December 2024
Department of Pharmacy, Faculty of Medical Sciences, University of Kragujevac, 34000 Kragujevac, Serbia.
Rupture of the thyrocervical trunk aneurysm into the thoracic cavity does not occur very often. It is an urgent condition due to hemorrhagic shock by massive hemothorax with potentially fatal consequences. Pregnancy and puerperium are additional risk factors for a rupture of the thyrocervical trunk aneurysm in patients with neurofibromatosis and aneurysms.
