Case Reports
A new sling technique in cervical radiculopathy due to vertebral artery loop compression : Case Report.
A 52-year-old woman had a 20-month history of progressive radiating pain in the left arm and numbness on C7 dermatome. ⋯ The patient's radiculopathic symptoms were improved and especially the aggravated pain by left head rotation subsided dramatically.

Metastatic brain tumors are the most common brain tumors in adults. Patients with metastatic brain tumors have poor prognoses with median survival of 6-12 months. Seizures are a major presenting symptom and cause of morbidity and mortality. In this article, risk factors for the onset of preoperative seizures and postoperative seizure control are examined. ⋯ The brain is a common site for metastases from numerous primary cancers, such as breast and lung. The identification of factors associated with onset of preoperative seizures as well as seizure control postoperatively could aid management strategies for patients with metastatic brain tumors. Patients with preoperative seizures who underwent resection tended to have good seizure control after surgery.

Clinically applicable hemodynamic risk factors to predict arteriovenous malformation (AVM) rupture are missing in the literature. The aim of this study was to use catheter angiography to identify hemodynamic parameters in ruptured and unruptured AVMs. ⋯ Ruptured AVMs have significantly prolonged venous drainage times compared with unruptured AVMs; this suggests restricted AVM drainage and increased blood pressure within the AVM nidus. Prospective studies are needed to determine the predictive power of these measurements.

Traditional endoscopic anterior cranial base resection involves the total removal of the ethmoidal cells, including the middle and superior turbinates. This is associated with increased volume of the nasal cavity postoperatively, with increased crusting and permanent change of the nasal airflow. Here we provide a step-by-step description of the technique and evaluate the feasibility of the superior ethmoidal approach for anterior cranial base resection with maximum exposure of the anterior cranial base while keeping the middle turbinates, uncinate processes, and ostiomeatal complexes intact. ⋯ The endoscopic superior ethmoidal approach for anterior cranial base resection is a feasible and safe approach that maximizes preservation of the nasal structures while providing optimal access to the anterior skull base. It can be used in pathologies that involve the anterior cranial base and do not involve the nasal structures.

Microvascular decompression (MVD) is the most useful treatment for hemifacial spasm (HFS). In cases of vertebral artery (VA) compression of the facial nerve, MVD is often difficult. In this study, we compared the outcome of the biomedical glue sling technique with the traditional technique in MVD for HFS involving the VA. ⋯ When the HFS were associated with the VA, the effective rate of biomedical glue sling technique of MVD was higher than the traditional technique, and there was no statistical difference between the 2 groups about the incidence of complication.
