Exact identification of feeding arteries, shunt points, and draining veins is essential in treating cavernous sinus dural arteriovenous fistula (CS dAVF). In addition to digital subtraction angiography (DSA) and 3-dimensional rotational angiography (3DRA), high-resolution cone beam computed tomography (CBCT; especially 80-kv high-resolution cone beam computed tomography) have been performed in recent years. We evaluated the efficacy of CBCT in treating CS dAVF. ⋯ The efficacy of CBCT in treating dAVF is illustrating the relationships among the bony structures and feeders, compartment of CS, and the position of the microcatheter. Detailed information obtained with CBCT can lead to fewer complications and more effective treatment.

Review Meta Analysis Comparative Study
Accuracy of Pedicle Screw Insertion among Three Image-Guided Navigation Systems: A Systematic Review and Meta-Analysis.
Many retrospective studies of pedicle screw placement have revealed that intraoperative navigation systems provide higher accuracy rates and safety than do free-hand techniques. The accuracy of various image-guided navigation systems has been studied; however, differences have not been well defined due to the lack of adequate evidence-based comparative studies. ⋯ Significant differences exist among CT Nav, 3D FluoroNav, and 2D FluoroNav. Our review suggests that 3D FluoroNav may be superior to the other 2 methods in reducing pedicle violation and that clinicians should consider 3D FluoroNav as a better choice.

Review Case Reports
Cerebral aneurysm associated with an arachnoid cyst: three case reports and a systematic review of literature.
Arachnoid cysts and intracranial aneurysms are not rare, but it is unusual for an aneurysm to be associated with an arachnoid cyst. The objective of this study was to reveal the association between arachnoid cysts and intracranial aneurysms. ⋯ It was difficult to diagnose a ruptured aneurysm in some cases with an arachnoid cyst because computed tomography scan showed atypical findings, such as no hemorrhage, intracystic localized hemorrhage, or subdural hematoma. This review revealed that aneurysms and arachnoid cysts were significantly located ipsilaterally and that they occurred together in relatively young patients.

The current surgical treatment of choice for refractory intracranial hypertension after traumatic brain injury (TBI) is decompressive craniectomy. Despite efficacy in control of intracranial pressure (ICP), its contribution to an improved outcome is debatable. ⋯ Cisternostomy proved to have an immediate effect in controlling ICP and improving brain oxygenation and metabolism.

Randomized Controlled Trial
Effect of Tranexamic Acid on Prevention of Hemorrhagic Mass Growth in Patients with Traumatic Brain Injury.
Intracranial hemorrhage is a common complication of traumatic brain injury (TBI). The purpose of this study is evaluation of the effect of tranexamic acid (TXA) on hemorrhagic mass growth in TBI patients. ⋯ Administration of a short dose of TXA does not lead to significant prevention of growth of posttraumatic hemorrhagic lesion or improvement of clinical outcomes.
