Monosegmental cervical disc herniation can be removed either by dorsal foraminotomy and sequesterectomy (Frykholm's method) or by a ventral approach with extensive removal of the affected disc with subsequent segmental fusion (modified Cloward's method). The choice of method largely depends on the surgeon's individual preference and experience. We evaluated the neurological outcomes of both surgical methods in a retrospective series of 100 consecutive patients (50 male, 50 female; mean age=47.7 years) who underwent surgery within a 3-year period. ⋯ Furthermore, the Cloward Group showed a trend towards better outcomes for paresis. Complete removal of the affected cervical disc via a ventral approach and segmental fusion results in a superior neurological performance in the short-term compared to a dorsal foraminotomy and nerve root decompression by sequestrectomy. However, assessment of the long-term outcome is required and further studies are required to confirm our results.

We present our preliminary experience with intraoperative near-infrared indocyanine green-videoangiography (ICG-VA) and analysis of blood flow dynamics using fluorescence intensity assessment in cerebral aneurysm clipping surgery. Thirty-nine patients with 43 intracranial aneurysms underwent microsurgical clipping. Intraoperative ICG-VA was performed before and after clip application. ⋯ ICG-VA provides high resolution images allowing real-time assessment of the blood flow in the parent artery and arterial branches, including the perforators. The intensity diagram is useful for providing a more objective record of the hemodynamics than the traditional ICG-VA, which relies more on subjective assessment and may allow interobserver variability. We conclude that ICG-VA, combined with the intensity diagram, can reduce the morbidity and complications associated with aneurysm clipping and improve patient outcomes.
