To compare facial pain outcomes from different surgical techniques for patients with idiopathic trigeminal neuralgia (TN) who continue to have persistent or recurrent TN despite multiple operations. ⋯ Although no procedure is best for all patients, PFE gives the operating surgeon the option of performing either a nondestructive (microvascular decompression) or destructive (partial sensory rhizotomy) procedure and is associated with better facial pain outcomes for this difficult patient group.

Early detection of vasospasm is essential for the treatment of delayed ischemic neurological deficits in subarachnoid hemorrhage (SAH). We evaluated cerebral blood oxygenation (CBO) changes after SAH employing quantitative time-resolved near-infrared spectroscopy (TR-NIRS) for this purpose. ⋯ TR-NIRS detected vasospasm by evaluating the CBO in the cortex and may be more sensitive than TCD, which assesses the blood flow velocity in the M1 portion. The cerebral oxygen metabolism in SAH might be reduced by brain damage due to aneurysmal rupture.

Anterior instrumentation has been used for surgical treatment of spinal tuberculosis, but there are different regimens of antituberculous chemotherapy used in combination with surgical intervention. The objective of this prospective study was to determine the efficacy of an antituberculous chemotherapy regimen by following a series of patients with spinal tuberculosis, for a minimum of 3 years, who underwent single-stage anterior radical debridement, autogenous bone grafting, and instrumentation. ⋯ In conclusion, postoperative chemotherapy with the 9-month three-drug regimen of isoniazid, rifampicin, and ethambutol is effective when combined with surgical treatment of spinal tuberculosis using single-stage anterior autogenous bone grafting and instrumentation.

Covered stents have recently become available for intracranial use, such as aneurysms, arterial dissections and carotid-cavernous fistulas (CCFs). However, there have been few reports of the successful application of covered stents for the treatment of traumatic CCFs (TCCFs). The purpose of this study is to investigate the efficacy and safety of endovascular treatment of TCCFs with covered stent. ⋯ Although larger sample and long-term follow-up are required, our series shows that covered stent is an effective, safe, and microinvasive method to treat TCCFs.
