Anterior retropharyngeal approach (ARPA) for high cervical spine.

Background: One of the major challenges in operating on the spine lies in taking an anterior approach for the high cervical spine. In patients with a short neck, Klippel-Fiel syndrome or when the C3 vertebra is high in relation to the hyoid bone, it will be difficult to access the C3 body. The transoral route is a highly contaminated zone, and therefore, no instrumentation or grafts can be placed through it.

C2 Superior Facetal Osteotomy: A Novel Technique in Complex Craniovertebral Junction Surgery for C1 Lateral Mass Screw Placement.

Complex craniovertebral junction (CVJ) defects account for a considerable proportion of CVJ diseases. Given the heavily assimilated C1, an unfavorable C1-C2 joint orientation, an overriding C2 superior facet, a low-hanging occiput, and an abnormal vertebral artery course with a high-riding vertebral artery, placement of C1 lateral mass screws might be difficult. To address this, a novel technique for placing C1 lateral mass screws that avoid vertebral artery injury, low-hanging occiput, and overriding C2 superior facet was developed in this study.

Reactivation of varicella zoster virus following trigeminal schwannoma resection.

Varicella zoster is found exclusively in humans. Infected people with this virus result in chickenpox followed by dormant virus within neural ganglia. This dormant virus, once activated, may affect any ganglia or nerves of the body but most commonly involves the thoracic, cervical and trigeminal nerves in decreasing order of frequency.

Comparative Study of Intraoperative Fluorescein and Indocyanine Green Videoangiography for Ruptured Cerebral Aneurysms Clipping: A Single Centre Study of 30 Cases.

 This study assesses the application of microscope integrated videoangiography techniques in aneurysm clipping surgery using Indocyanine Green and Fluorescein fluorophores and evaluates merits and demerits of each technique.  Total 30 patients of cerebral aneurysmal clipping were included. Standard microsurgical procedures were done.

C2 Screw fixation techniques in atlantoaxial instability: A technical review.

Atlantoaxial instability (AAI) is surgically a complex entity due to its proximity to vital neurovascular structures. C1-C2 fusion has been an established standard in its treatment for a considerable time now. Here, we have outlined the most common techniques for C2 screw fixation in practice at present such as C2 pedicle, C2 pars, C2 translaminar, C2 subfacetal, C2-C3 transfacetal, and C2 inferior facet screw.

Ruptured mirror DACA aneurysm: A rare case report and review of literature.

Bilateral distal anterior cerebral artery (DACA) aneurysms also called "kissing aneurysms" or "mirror aneurysm" are extremely rare, accounting for only 0.2% of all intracranial aneurysms. There have only been a few examples of mirror DACA aneurysms reported in the literature.
