Rotational vertebral artery occlusion syndrome refers to vertebrobasilar insufficiency as a result of mechanical occlusion or stenosis of the vertebral artery by head rotation. In most cases, symptoms are produced on extension or rotation to one side. No case of bow hunter's syndrome with bilateral presentation at the C4 level has yet been reported. ⋯ Bony obstruction of the vertebral artery on head rotation tends to occur at levels C4 and below, affecting the ipsilateral side. In this rare case, symptomatic bilateral vertebral artery stenosis occurred as a result of bony compression and was symptomatic on head rotation both to the right and to the left. This stenosis was improved with anterior decompression bilaterally, and no further events occurred postoperatively.

The CO2 laser has a long record of use in neurosurgery. However, its utility has been limited by its bulky design and the challenge of using it with the operating microscope. With the development of the OmniGuide fiber, a technology that delivers the beam through flexible hollow-core photonic bandgap mirrors, the laser can now be held and used with greater ease and accuracy. ⋯ The CO2 laser is a useful addition to the neurosurgical armamentarium for treating lesions in the brainstem, thalamus, and spinal cord. Its primary utility lies in its ability to create focused cortisectomies safely and to shrink cavernous malformations away from eloquent hemosiderin-stained brain.

This overview of neurosurgery in India during the last six decades gives a holistic perspective of the phenomenal advances made. Neurosurgical education, the change in clinical spectrum of diseases and their presentation, evolution of various subspecialties and societies, the state of research, the issues peculiar to India, including the urban-rural health divide, the increasing role of information and communication technology in neurosurgery, and the gradual but definite global recognition of Indian neurosurgery will be addressed.
