Review Meta Analysis Comparative Study
Comparison of the Therapeutic Efficacy of Surgery with or without Adjuvant Radiotherapy versus Radiotherapy Alone for Metastatic Spinal Cord Compression: A Meta-Analysis.
Spinal metastases are 20 times more common than primary spinal tumors and often cause metastatic spinal cord compression (MSCC). Clinical manifestations (e.g., pain and neurologic dysfunction) adversely affect patients' quality of life. Radiotherapy (RT), chemotherapy, and surgery are the major therapeutic strategies for MSCC. There is some evidence that combining surgery with adjuvant RT may be a better option. ⋯ Further studies are needed to investigate the effects of these interventions on quality of life and to identify the best therapeutic strategy for patients with MSCC.

Recanalization has been reported in large or giant aneurysms of the internal carotid artery (ICA) addressed by high-flow bypass and endovascular treatment. Aneurysmal recanalization may be attributable to retrograde blood flow into the aneurysm through the ICA branches, such as the ophthalmic artery or the meningohypophyseal trunk, or through the surgically created bypass. We modified the endovascular treatment of aneurysms to prevent retrograde flow and evaluated the long-term efficacy of our method. ⋯ Prevention of retrograde flow into the aneurysm by coil embolization with high-flow bypass is a safe and effective method. It prevents the recanalization of large or giant ICA aneurysms.

A recent study reported on the relatively safe area in the frontal lobe for performance of neurological interventions; however, no study on the posterior safe area has been reported. In this study, using diffusion tensor tractography, we attempted to identify the safe area in the parieto-occipital lobe in healthy subjects. ⋯ According to our findings, the safe area was located in the posterolateral portion of the parieto-occipital lobe in the shape of a triangle. However, we found no safe area in the deep white matter around the lateral ventricle.
