Unruptured paraclinoid aneurysms are often asymptomatic, and endovascular coiling is the main treatment. However, endovascular treatment of these lesions still leads to neurologic complications. We aimed to identify predictors of neurologic complications in these lesions. ⋯ Unruptured paraclinoid aneurysms after endovascular treatments had 5.2% of neurologic complications. Cerebral ischemic comorbidities and aneurysm size were predictors of neurologic complications.

Clinical Trial
Complementary relation between direct and indirect bypass in progress of collateral circulation in moyamoya disease.
One of the important aims of surgery for moyamoya disease is to establish indirect revascularization. The purpose of this study was to assess the progress of the middle meningeal artery (MMA) after our novel preservation method and to evaluate the relation between direct and indirect bypass in the chronic stage. ⋯ In moyamoya disease, the MMA could be developed as a pathway for indirect revascularization even after simple preservation, especially in pediatric patients. The progress of the MMA and the STA occurs through their synergistic interaction, and the balance might be decided based on their complementary relations in the chronic stage.

Outcome prediction is of paramount importance in traumatic brain injury. Our objective of conducting this prospective study was to identify the predictors needed to formulate a prognostic score. ⋯ The model based on cisternal status described in the study is technically simple and conveys the information regarding the outcome to the treating neurosurgeon. Because the score obtained seems to have low interobserver variation, we believe that it can be a useful tool not only in recording data in case files and interphysician communication but also in research into traumatic brain injury.

Comparative Study
Superior Petrosal Vein Sacrifice During Microvascular Decompression: Perioperative Complication Rates and Comparison to Venous Preservation.
To investigate potential effect of sacrifice of the superior petrosal vein (SPV) on postoperative complications after microvascular decompression (MVD). ⋯ Sacrifice of the SPV is often performed during MVD. This is associated with a complication rate that is significant in frequency and severity compared with preserving the vein. SPV sacrifice should be limited to cases where it is deemed absolutely necessary for successful cranial nerve decompression.

Case Reports
Prevention of Thromboembolic Complications after Spine Surgery by the Use of Low-molecular-weight Heparin.
This study aimed to evaluate the effectiveness and safety of the use of low-molecular-weight heparin (LMWH) in the prevention of thromboembolic complications after spine surgery. ⋯ The use of LMWH significantly decreases the incidence of thrombosis and thromboembolic complications after spine surgery, but increase the incision bleeding, leading to an elevated risk of symptomatic spinal epidural hematoma.
